Walkthrough

The changes introduce a new third screen into the navigation flow and refactor the overall navigation architecture. In the profile module, a new ProfileChild.Third branch is added so that clicking the “Nav to third” button in ProfileScreen now calls ThirdScreenUi. The home navigation logic is reworked by replacing the previous StackNavigation instance with a dedicated HomeNavigator that pushes and pops screen configurations using createScreenComponent. Similar restructuring is applied in the root and signed-in flows, where navigation actions are now defined through dedicated interfaces (such as HomeNavigation, ProfileNavHostNavigation, RootNavHostNavigation, and SignedInNavHostNavigation) and their corresponding Navigator classes. Additionally, the AppComponentFactory methods have been updated to improve type specificity when creating screen components. Overall, the modifications standardize and encapsulate navigation actions and component instantiation across the application.

🧹 Nitpick comments (10)
shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/secondScreen/SecondScreenNavigation.kt (1)

7-7: Consider validating or strongly typing the “id” parameter.

Depending on the use case for “id”, ensure no unexpected null or empty values are used. Introducing a specific value class or non-empty string checks might improve correctness.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/firstScreen/FirstScreenNavigation.kt (1)

5-7: Strong architectural improvement!

The refactoring from a data class to an interface with NavigationActions brings several benefits:

  • Better encapsulation of navigation logic
  • More flexible implementation options
  • Type-safe navigation through the receiver type pattern

Consider documenting the navigation contract with KDoc comments to help other developers understand the navigation flow.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/thirdScreen/ThirdScreenNavigation.kt (1)

5-7: Consider adding a brief KDoc for clarity.
This extension-based navigation approach is consistent with your refactoring pattern; however, a short KDoc on “pop()” can help other contributors quickly understand its purpose and usage.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/profile/ProfileNavHostNavigation.kt (1)

16-19: Constructor-level design is straightforward.
Passing a lambda for navigation to login is a neat dependency inversion; consider adding tests for the new stackNavigator to ensure it initializes and navigates correctly.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/home/HomeNavHostComponent.kt (1)

28-28: Consider injecting the navigator for improved testability.

Currently, you're instantiating HomeNavigator inline. Injecting it through a parameter or a factory can facilitate mocking or swapping implementations in tests, enhancing maintainability.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/root/RootNavHostComponent.kt (1)

29-29: Consider injecting the navigator rather than creating it directly.

Injecting the RootNavHostNavigator can improve testability and allow for more flexible composition if different navigator implementations are required.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/profileScreen/ProfileComponent.kt (1)

19-20: Consider making the navigation message configurable.

The hard-coded message "hello third from profile" could be made configurable through a constant or configuration parameter for better maintainability and reusability.

-        override fun onThird() = navigateToThird("hello third from profile")
+        override fun onThird() = navigateToThird(NavigationConfig.THIRD_SCREEN_MESSAGE)
shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/root/RootNavHostNavigation.kt (1)

14-24: Consider adding KDoc documentation.

The implementation is clean and follows best practices. Consider adding KDoc documentation to describe the navigation flow and the purpose of each navigation method.

+/**
+ * Navigator implementation for root-level navigation.
+ * Manages transitions between login and signed-in states.
+ */
 internal class RootNavHostNavigator: RootNavHostNavigation {
     override val slotNavigator: SlotNavigation<RootConfig> = SlotNavigation()

+    /**
+     * Transitions from login to signed-in state.
+     */
     override fun LoginComponent.toSignedIn() {
         slotNavigator.activate(RootConfig.SignedIn())
     }

+    /**
+     * Transitions from signed-in to login state.
+     */
     override fun SignedInNavHostComponent.toLogin() {
         slotNavigator.activate(RootConfig.Login)
     }
 }
shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/home/HomeNavigation.kt (1)

19-34: LGTM! Clean implementation of navigation logic.

The implementation:

  • Properly initializes the navigator
  • Uses extension functions for clear API
  • Follows consistent patterns for push/pop operations

Consider adding documentation to describe the navigation flow.

 internal class HomeNavigator : HomeNavigation {
+    /**
+     * Implements navigation between First, Second, and Third screens using a stack-based approach.
+     * Navigation flow:
+     * - First -> Second -> Third
+     * - Pop operations return to previous screen
+     */
     override val navigator = StackNavigation<HomeConfig>()
androidApp/src/main/kotlin/app/futured/kmptemplate/android/ui/screen/ProfileScreenUi.kt (1)

59-61: Use string resource for button text.

The button text "Nav to third" is hardcoded. Consider using a string resource for better maintainability and localization support.

 Button(onClick = actions::onThird) {
-    Text("Nav to third")
+    Text(kmpStringResource(MR.strings.nav_to_third))
 }

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/base/AppComponentFactory.kt (2)

22-24: Great improvement to type safety!

The changes to createScreenComponent make the API more type-safe and explicit by:

  • Making the method name clearer about its purpose
  • Adding type parameter N to ensure components only receive compatible navigation actions
  • Establishing a clear relationship between components and their navigation types

41-41: LGTM! Clear and consistent naming.

The rename to createAppComponent improves clarity by explicitly stating its purpose and maintaining consistency with createScreenComponent.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/loginScreen/LoginScreenNavigation.kt (1)

5-7: Well-structured navigation interface!

The transition from a data class to an interface with an extension function is a good design choice that:

  • Improves abstraction and flexibility
  • Makes the code more testable
  • Follows Kotlin idioms with the extension function approach
shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/loginScreen/LoginComponent.kt (2)

14-16: Clean constructor implementation with interface delegation!

The changes improve the code by:

  • Directly assigning constructor parameters
  • Using interface delegation with by navigation
  • Following Kotlin conventions for component initialization

19-19: Simplified action implementation!

The direct call to toSignedIn() is more concise than the previous navigation.toSignedIn() due to interface delegation.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/root/RootNavHostFactory.kt (1)

10-10: Verify the new component creation method.

The change from createComponent to createAppComponent aligns with the navigation refactoring. However, we should verify that the new method exists and handles component creation correctly.

✅ Verification successful

🏁 Script executed:

#!/bin/bash
# Search for the createAppComponent method definition and its usages
ast-grep --pattern 'fun createAppComponent<$_>($_) { $$$ }'

# Search for other similar factory methods to ensure consistent usage
rg "createAppComponent|createComponent" -A 3

Length of output: 4322


Component creation method verified.

The use of AppComponentFactory.createAppComponent in RootNavHostFactory is consistent with its definition in AppComponentFactory and with similar usages elsewhere. No issues were found with the method update.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/secondScreen/SecondScreenNavigation.kt (1)

5-8: Interface-based approach improves clarity and modularity.

Defining an interface for navigation actions is a clean approach, enabling clear separation of concerns and easier testability.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/secondScreen/SecondComponent.kt (4)

25-28: LGTM! Clean implementation of navigation delegation.

The component initialization is well-structured with proper delegation to SecondScreenNavigation.


37-37: LGTM! Simplified navigation call.

The direct use of navigateToThird(result) through delegation improves code readability while maintaining functionality.


61-61: LGTM! Consistent navigation pattern.

The simplified pop() call maintains consistency with the navigation delegation pattern used throughout the component.


47-48: Verify consistent usage of createAppComponent.

The switch to createAppComponent looks good, but let's ensure this pattern is consistently applied across the codebase.

Also applies to: 52-55

✅ Verification successful

🏁 Script executed:

Consistent usage of createAppComponent confirmed.

  • No occurrences of the old createComponent method were found.
  • All component creations across the codebase now correctly use createAppComponent, including in the SecondComponent.kt (both Fruit and Vegetable PickerComponent) and other related files.
shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/firstScreen/FirstScreenNavigation.kt (1)

6-6: Verify navigation implementation in FirstComponent

Length of output: 998


Navigation implementation in FirstComponent verified

The extension function "navigateToSecond" is declared in FirstScreenNavigation.kt and properly overridden in HomeNavigation.kt. Additionally, FirstComponent.kt uses the function without issues, confirming that the navigation setup is implemented as expected.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/firstScreen/FirstComponent.kt (2)

27-27: LGTM! Good use of Kotlin's delegation pattern.

The use of interface delegation with by navigation is a clean approach that reduces boilerplate while making the component's navigation capabilities explicit.


38-38: LGTM! Verify navigation method exists.

The simplified navigation call aligns with the navigation refactoring. Let's verify the method exists in the interface:

✅ Verification successful

🏁 Script executed:

#!/bin/bash
# Search for navigateToSecond() method definition
ast-grep --pattern 'interface FirstScreenNavigation {
  $$$
  fun navigateToSecond()
  $$$

Length of output: 778


LGTM! Navigation method verified.

Based on our investigation, the method navigateToSecond() is defined as an extension function on FirstComponent in FirstScreenNavigation.kt. The change from navigation.toSecond() to navigateToSecond() is consistent with the navigation refactoring since this method leverages the navigation delegation introduced in FirstComponent.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/signedIn/SignedInNavHostNavigation.kt (1)

5-7: Interface approach looks good.
Switching from data class to interface aligns well with the new navigation structure, and extending NavigationActions keeps it consistent.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/profile/ProfileNavHostNavigation.kt (5)

3-10: Imports appear relevant and necessary.
All introduced imports support the reworked navigation logic, so this looks appropriate.


12-13: Interface structure is clean and modular.
Extending both ProfileScreenNavigation and ThirdScreenNavigation promotes cohesive, reusable navigation actions. Good use of internal visibility.


21-21: Login navigation is simple and intuitive.
Delegating to the provided lambda neatly keeps the navigation logic decoupled from the ProfileScreen.


23-24: Validate or document the “id” parameter.
If “id” can be null or invalid, clarify handling in code or doc comments. Otherwise, this is a clean approach.


27-28: Pop extension is consistent with the existing stack approach.
This mirrors the established pattern for modular screen navigation. No immediate issues observed.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/home/HomeNavHostComponent.kt (5)

31-31: Traversal source update looks good.

Switching to “homeNavigator.navigator” as the source is a clean approach to manage the child stack.


39-41: Verify type alignment for navigation injection.

Ensure that “homeNavigator” correctly implements the “FirstScreenNavigation” contract when passed to the “createScreenComponent” function.


46-48: Consistent approach for second screen.

The updated “createScreenComponent” usage with “homeNavigator” is consistent with the pattern used for the first screen.


53-55: Third screen integration is properly wired.

Leveraging “createScreenComponent” with “homeNavigator” and the config arguments follows the same robust pattern.


63-68: Navigation actions are clearly encapsulated.

Using “homeNavigator.navigator.navigate” and “pop()” in the actions object properly encapsulates navigation logic within your new structure.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/root/RootNavHostComponent.kt (6)

11-11: New import for LoginScreen is valid.

The direct import aligns with the updated creation logic in this component.


35-35: Slot source reference updated correctly.

Pointing “childSlot” to “rootNavigator.slotNavigator” keeps the root flow centralized.


41-47: Revised login path creation.

Using “createScreenComponent<LoginComponent, LoginScreenNavigation>” and passing “rootNavigator” as the navigation target is coherent with the new architecture.


50-55: Signed-in flow properly delegated to SignedInNavHostComponent.

Passing a callback for reactivation of the Login screen is correct. Double-check that the “rootNavigator.slotNavigator.activate(RootConfig.Login)” call covers all edge cases (e.g., session timeouts).


63-63: Initial flow activation is straightforward.

Activating RootConfig.Login on creation ensures users are directed to the login screen by default.


83-89: Deep link configuration is handled cleanly.

Mapping DeepLinkDestination to RootConfig before activating is a clear approach for slot-based navigation.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/profileScreen/ProfileScreenNavigation.kt (1)

5-8: Shifting from data class to interface improves flexibility.

Defining navigation actions as interface methods decouples them from any stored data and helps keep the screen’s responsibilities lean.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/profileScreen/ProfileScreen.kt (1)

11-11: LGTM!

The new onThird() method is correctly added to the Actions interface, following the existing naming convention.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/profileScreen/ProfileComponent.kt (1)

16-16: LGTM!

Good use of the Kotlin delegation pattern with by navigation to implement the ProfileScreenNavigation interface.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/root/RootNavHostNavigation.kt (1)

10-12: LGTM!

Good interface design with clear separation of navigation concerns and proper composition of navigation interfaces.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/ui/thirdScreen/ThirdComponent.kt (2)

20-20: LGTM!

Good use of the Kotlin delegation pattern with by navigation to implement the ThirdScreenNavigation interface.


25-25: Consider adding error handling for navigation.

The pop() navigation call could fail in certain edge cases. Consider wrapping it in a try-catch block to handle potential navigation failures gracefully.

-        override fun onBack() = pop()
+        override fun onBack() = try {
+            pop()
+        } catch (e: IllegalStateException) {
+            // Log navigation failure
+            logger.error("Navigation pop failed", e)
+        }
✅ Verification successful

I'm going to search for the definition of pop() in the repository to determine if it already handles error cases or if additional error handling is needed. This will help us verify the need to wrap pop() in a try-catch block.

I'm going to re-run the search command with an escaped parenthesis to correctly find the definition of pop() in the repository:

Navigation error handling review in ThirdComponent.kt

Based on our search:
• The navigation “pop()” implementations (e.g. in HomeNavHostComponent.kt and ProfileNavHostComponent.kt) simply delegate to lower-level navigators without wrapping the call in a try-catch.
• None of the existing implementations add explicit error handling for a failed pop() call.

Thus, adding error handling (for example, using a try-catch block around pop() and logging an error when a failure occurs) in ThirdComponent.kt appears justified.

4-5: LGTM! Clean addition of third screen imports.

The imports are properly organized and follow the project's structure.


29-30: LGTM! Well-structured configuration for third screen.

The Third configuration is properly serializable and follows the existing pattern.


35-35: LGTM! Consistent child interface extension.

The Third child class follows the same pattern as the existing Profile child class.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/home/HomeNavigation.kt (1)

15-17: LGTM! Well-designed navigation interface.

The interface properly extends all required screen navigations and encapsulates the navigator.

androidApp/src/main/kotlin/app/futured/kmptemplate/android/ui/navigation/ProfileNavHostUi.kt (1)

47-47: LGTM! Clean integration of third screen.

The third screen case is properly integrated into the navigation host with consistent modifier usage.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/profile/ProfileNavHostComponent.kt (4)

9-10: LGTM!

The imports are correctly added to support the new third screen functionality.


23-23: LGTM!

The constructor parameter change simplifies the navigation interface by accepting a direct callback instead of a navigation interface.


27-28: LGTM!

The navigation logic is now properly encapsulated behind an interface, improving testability and maintainability.


43-49: Verify the third screen integration.

The third screen configuration is correctly integrated, following the established pattern for component creation and navigation wiring.

✅ Verification successful

Third Screen Integration Verified

The integration for the third screen is confirmed as correct. The output shows that all key components—ThirdComponent, ThirdScreenNavigation, and ThirdScreenArgs—are properly implemented and follow the established component creation and navigation wiring patterns.

shared/feature/src/commonMain/kotlin/app/futured/kmptemplate/feature/navigation/signedIn/SignedInNavHostComponent.kt (3)

25-25: LGTM!

The constructor parameter change is consistent with the navigation refactoring pattern used in ProfileNavHostComponent.


39-39: LGTM!

The change standardizes component creation by using createAppComponent consistently.


46-49: LGTM!

The changes maintain consistency with the home component and properly wire the navigation callback.

14-26: Consider adding navigation transition customization.

While the basic navigation implementation is correct, you might want to consider customizing the navigation transitions for a better user experience. SwiftUI's NavigationStack allows for custom transitions via modifiers.

Example enhancement:

 DecomposeNavigationStack(
     kotlinStack: stack,
     setPath: actions.navigate
 ) { child in
     switch onEnum(of: child) {
     case .profile(let entry):
-        ProfileView(ProfileViewModel(entry.screen))
+        ProfileView(ProfileViewModel(entry.screen))
+            .transition(.slide)
     case .third(let entry):
-        ThirdView(ThirdViewModel(entry.screen))
+        ThirdView(ThirdViewModel(entry.screen))
+            .transition(.slide)
     }
 }

4-7: LGTM! Clean protocol extension.

The new onThirdClick() method is properly added to the protocol, maintaining consistency with the existing pattern.


21-23: LGTM! Implementation follows established patterns.

The onThirdClick() implementation correctly delegates to the actions object, consistent with the existing onLogoutClick implementation.

22-23: LGTM! Navigation case handler properly implemented.

The new .third case is correctly implemented following the same pattern as the existing .profile case, maintaining consistency in the navigation architecture.


6-7: Verify type safety of navigation actions.

The navigation stack and actions are properly typed with ProfileConfig and ProfileChild, but let's verify that all possible navigation cases are handled correctly across the codebase.

🛠️ Refactor suggestion

Localize the navigation button text.

The button text "Navigate to third" is hardcoded, while other text in the view uses localization (e.g., Localizable.login_screen_title.localized). Consider adding a localized string for consistency.

Example fix:

-            Button("Navigate to third", action: viewModel.onThirdClick)
+            Button(Localizable.profile_navigate_to_third.localized, action: viewModel.onThirdClick)
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
