filePath为null 调试报错

[practicingman]

 String filePath = await _channel.invokeMethod(
      'saveFile',
      <String, dynamic>{
        'fileData': fileData,
        'title': title,
        'description': description
      },
    );
    debugPrint("saved filePath:" + filePath);  《======= 这里报错
    //process ios return filePath
    if(filePath.startsWith("file://")){
      filePath=filePath.replaceAll("file://", "");
    }
    return  filePath;
  }

iOS 13.1 (17A844)

filePath永远返回为null
我同事说IOS不会返回路径，是这个原因吗？
现在调试一直报错

谢谢

Sorry, I don't understand Chinese but I can confirm this issue.
I found the debugPrint result too. This is my debug result.

Xcode build done. 22.8s PHImageFileDataKey = {length = 538642, bytes = 0x89504e47 0d0a1a0a 0000000d 49484452 ... 49454e44 ae426082 }; PHImageFileOrientationKey = 0; PHImageFileUTIKey = "public.png"; PHImageResultIsDegradedKey = 0; PHImageResultRequestIDKey = 1; } [VERBOSE-2:ui_dart_state.cc(157)] Unhandled Exception: Invalid argument(s) #0 _StringBase.+ (dart:core-patch/string_patch.dart:265:57) #1 ImagePickerSaver.saveFile package:image_picker_saver/image_picker_saver.dart:85 <asynchronous suspension> #2 _HomeState.takeScreenShot package:screen_cap_test/home.dart:50 <asynchronous suspension> #3 _HomeState.build.<anonymous closure> package:screen_cap_test/home.dart:149 #4 _InkResponseState._handleTap package:flutter/…/material/ink_well.dart:706 #5 _InkResponseState.build.<anonymous closure> package:flutter/…/material/ink_well.dart:789 #6 GestureRecognizer.invokeCallback package:flutter/…/gestures/recognizer.dart:182 #7 TapGestureRecognizer.handleTapUp package:flutter/…/gestures/tap.dart:486 #8 BaseTapGestureRecognizer._checkUp package:flutter/…/gestures/tap.dart:264 #9 BaseTapGestureRecognizer.handlePrimaryPointer package:flutter/…/gestures/tap.dart:199 #1<…>

Should we remove this debug result ?

Thank you for your awesome plugin. It's really help me a lot :)
