Cannot build to WASM with flutter_quill

[shechren]

Is there an existing issue for this?

• I have searched the existing issues

The question

https://docs.flutter.dev/platform-integration/web/wasm

I found a problem when i was built to Web in WASM.
So i check the flutter pub deps and found the reason. that flutter_keyboard_visibility_web wasn't updated (dart:html to web) and I think it's uncertainly to will be done.
However please tell me how can I dodge this problem within use the flutter_quill till flutter_keyboard_Visibility_web's update.

log is as follows:

Target dart2wasm failed: ProcessException: Process exited abnormally with exit code 64:
*NOTE*: Compilation to WasmGC is experimental.
The support may change, or be removed, with no advance notice.

Compiling lib\main.dart for the Web...                             62.8s
Error: Failed to compile application for the Web.

Yeahhhh...not sure how this will play out but looking at flutter_keyboard_visibility_web: ^2.0.0 there has not been any updates in years and the likely hood of quill to undergo some big migration just so we can build with wasm.

[dxvid-pts]

dart:html is superceeded by package:web. See https://dart.dev/interop/js-interop/package-web, https://docs.flutter.dev/platform-integration/web/wasm and this talk (https://www.youtube.com/watch?v=qx42r29HhcM) for more information.

A migration can also be done partially.

application

You can't dodge it. Quill has the keyboard package as dependency, hence until the keyboard package gets updated and quill updates the dependency as well you are kinda stuck.

[dxvid-pts]

True, we are dependent on the keyboard package but quill itself could be updated in the meantime:)

[putnokiabel]

True, we are dependent on the keyboard package but quill itself could be updated in the meantime:)

Yep, as long as flutter_quill itself does not use html (which it currently does), you could easily add a dependency_override for flutter_keyboard_visibility_web (as it has a PR ready for wasm support already)

Exactly

@singerdmx is there a reason this was closed? I could not find any PR for this and flutter_quill still depends on the html package

[dxvid-pts]

I already migrated a few open-source packages to package:web. If help is needed I can help.

I believe he was referring to this pull request: MisterJimson/flutter_keyboard_visibility#155. raldhafiri has already worked on getting flutter_keyboard_visibility to compile for ASM and is waiting for this PR to be merged into the MisterJimson repository. As a workaround, while MisterJimson hasn't updated his package yet, you can add the following to your pubspec.yaml to use raldhafiri's version:

dependency_overrides:
flutter_keyboard_visibility_web:
    git:
    url: https://github.com/raldhafiri/flutter_keyboard_visibility.git
    ref: master
    path: flutter_keyboard_visibility_web

Does this issue still persists?

Thank you for the offer, in case you're still interested, feel free to take a look at #2230, #2220, and #1998.

Does this issue still persists?

Should still do since flutter_keyboard_visibility doesn't use package:web yet.

Will have to introduce a replacement.

[EchoEllet]

Should be solved once #1889 is solved.

Update: Fixed in #1889 by forking and replacing flutter_keyboard_visibility with flutter_keyboard_visibility_temp_fork.

[EchoEllet]

Fixed in 10.8.1.

@shechren Can you confirm if you're still facing this issue or any related issues to Wasm support?
