[Add2App] No constructor 'Text.' with matching arguments declared in class 'Text'.

[zerryzarax]

I'm using flutter module in my existing iOS app. While making changes Text, I use hot reload to see the output. It was working bad, Whether I use an emulator or iphone.（only way it work fine，it‘s using ’flutter run‘ directly rather than using xcode run） its giving me the exception like this:

======== Exception caught by widgets library =======================================================
The following NoSuchMethodError was thrown building ContainerMain(dirty, state: _ContainerMain#f0c96):
No constructor 'Text.' with matching arguments declared in class 'Text'.
Receiver: Text

example code:

void main() {
  runZonedGuarded<Future<Null>>(() async {
    runApp(ContainerMain(inApp: true, appType: global.AppType.xxxxx,));

    }, (dynamic error, StackTrace stackTrace) async {
      if (kReleaseMode) {
        reportError(error, stackTrace);
      }
  });
}

class _ContainerMain extends State<ContainerMain> {
  bool? inApp;

  _ContainerMain({bool inApp = true}) {
    this.inApp = inApp;
  }

  @override
  void initState() {

    if (!this.inApp!) {
      super.initState();
    }
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      // builder: Hybrid.init(),
      home: Container(alignment: Alignment.center, child: Text("tetetet2"), color: Colors.yellow,),
    );
  }
}

Hi @zerryzarax
From the logs:

Receiver: Text
Tried calling: new Text.()

It looks like it's caused by a syntax error. It should be Text() rather than Text.().
So, try correcting it to see if the issue is still reproducible. Thanks!

[zerryzarax]

hi @huycozy
If it is like you said, the direct build should report an error, but the direct build can run normally, and the interface looks normal. And I use 'flutter attach' in the direct build mode of xcode, and then I just change 'Text("tetetet")' to 'Text("tetetet2"), and then use android studio to save the file to trigger hot reload. As a result, the above error was triggered. I suspect there is something wrong in xcode_backend.dart. Is it inconsistent with the code that android studio directly triggers flutter run?
thank you for your reply

[zerryzarax]

At present, I have found a temporary adaptation solution:

1. Must use 'FlutterEngineGroup'
2. App needs to support hot restart mode
3. When saving a file in android studio to trigger hot reload, although an error will be reported, only one hot restart is required, so that hot reload can also be used normally.

Hello @zerryzarax. Thank you for the information. Can you provide a minimal, reproducible example in the form of a public repository so that we can investigate this issue?

[zerryzarax]

Hello @zerryzarax. Thank you for the information. Can you provide a minimal, reproducible example in the form of a public repository so that we can investigate this issue?

hi @exaby73 ，there is a bug demo，https://github.com/zerryzarax/flutter-3.0.3-bug-test-demo

[exaby73]

@zerryzarax I am unable to run the project you have provided. Could you provide some steps to run the project which has caused you to get this error?

[zerryzarax]

@exaby73
The following are the steps to run the project:

1. Download the bug demo source code
2. Use android studio to open the path/to/flutter_bug_demo/dart_demo directory
3. Use the "flutter pub get" command in the terminal of android studio until the successful prompt appears
4. On the computer terminal "cd path/to/XcodeFlutterEngineGroupDemo", then "pod install". If cocospod is not installed, you need to install it
5. Use xcode to open XcodeFlutterEngineGroupDemo.xcworkspace in the XcodeFlutterEngineGroupDemo directory, and run the simulator directly
6. Click the program "打开flutter页面", you can see the flutter debug prompt
7. The dart_demo project of android studio, "flutter attach" program running in the emulator
8. When the attach is successful, you can modify the Text("testtest2") to Text("testtest3") in the container.dart file under the dart_demo project, and then save the changes to trigger hot reload, so that you can see the error.

Hi @zerryzarax, thanks for providing very detailed steps to reproduce.

• This issue is reproducible on the latest stable and master channels. The sample code can be found at [Add2App] No constructor 'Text.' with matching arguments declared in class 'Text'. #109602 (comment).

• The issue is happening with Hot reload whilst Hot restart is working normally.

• This issue affects iOS side, it works normally on Android side with sample code at https://github.com/flutter/samples/tree/main/add_to_app/plugin

  • iOS: ❌
  • Android: ✅

  ✅: No Issue ❌: Issue reproduced

Not sure why the String arg isn't being passed through to the constructor, I can see arguments and argumentNames is nil when NoSuchMethodError is thrown.

  // The compiler emits a call to _throwNew when it cannot resolve a static
  // method at compile time. The receiver is actually the literal class of the
  // unresolved method.
  @pragma("vm:entry-point", "call")
  static void _throwNew(
      Object receiver,
      String memberName,
      int invocationType,
      int typeArgumentsLength,
      Object? typeArguments,
      List? arguments,
      List? argumentNames) {
    throw new NoSuchMethodError._withType(receiver, memberName, invocationType,
        typeArgumentsLength, typeArguments, arguments, argumentNames);
  }

This doesn't reproduce from the Flutter module, just from the embedded add-to-app case.
