[Bug] Error: The non-abstract class '_AppFlowyInputState' is missing implementations

[bynicodevelop]

Bug Description

I am currently testing your editor.

However, upon starting, I am encountering several errors on both MacOS and the web.

How to Reproduce

Here is the code that I have produced:

version: 1.0.0+1

environment:
  sdk: ">=2.19.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  appflowy_editor: ^0.0.9

import "package:appflowy_editor/appflowy_editor.dart";
import "package:flutter/material.dart";

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      localizationsDelegates: const [
        AppFlowyEditorLocalizations.delegate,
      ],
      home: const HomeScreen(),
    );
  }
}

class HomeScreen extends StatefulWidget {
  const HomeScreen({super.key});

  @override
  State<HomeScreen> createState() => _HomeScreenState();
}

class _HomeScreenState extends State<HomeScreen> {
  final EditorState editorState = EditorState.empty();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Padding(
        padding: EdgeInsets.symmetric(
          horizontal: MediaQuery.of(context).size.width * 0.25,
        ),
        child: Column(
          children: [
            AppFlowyEditor(
              editorState: editorState,
            )
          ],
        ),
      ),
    );
  }
}

Expected Behavior

The error is as follows:

Launching lib/main.dart on Chrome in debug mode...
lib/main.dart:1
: Error: The non-abstract class '_AppFlowyInputState' is missing implementations for these members:
../…/service/input_service.dart:60
 - TextInputClient.didChangeInputControl
 - TextInputClient.performSelector
Try to either
 - provide an implementation,
 - inherit an implementation from a superclass or mixin,
 - mark the class as abstract, or
 - provide a 'noSuchMethod' implementation.

Is this a problem with my setup or a known bug? I looked into the issues and I haven't found a similar case.

Hi @bynicodevelop You can try to downgrade flutter to 3.3.10 version.

[annieappflowy]

Is this resolved? @bynicodevelop

[Merrit]

Can confirm that on Linux using Flutter 3.3.10 resolves this issue for me.

[lovespreader]

Hi @appflowy Is there any chance the Appflowy Editor package to be dependent on Flutter 3.7 anytime soon?

(Great work by the way, love this editor!)

[annieappflowy]

Is this resolved? @bynicodevelop

I get the same error when I install via docker-compose

[saru2020]

I'm facing the same error,
tried downgrading to v3.3.10 but still facing issues

[LucasXu0]

Flutter with 3.3.10 should not contain those APIs.

[tyjak]

I get the same error when I install via docker-compose

I tried with Flutter 3.3.10 same result...

I changed line 24 in Dockerfile :
RUN git clone https://github.com/flutter/flutter.git --branch 3.3.10 $HOME/.local/flutter

Is it the way to do it to change the version of flutter ?

[Dieterbe]

Is there a fix for this in the works? I have to use 3.7 for a different project.. thanks!

[borracho-mejor]

Same error here. Trying for the first time today, using the docker-compose instruction here: https://github.com/AppFlowy-IO/AppFlowy-Docs/blob/main/essential-documentation/install-appflowy/installation-methods/installing-with-docker.md

I changed line 24 in Dockerfile :
RUN git clone https://github.com/flutter/flutter.git --branch 3.3.10 $HOME/.local/flutter

I also tried this, and the same error occurred. Extremely interesting app!! I hope we can try it out soon!

[leeyaal]

Same error, any solutions?

[LucasXu0]

Hey, All. We're migrating to Flutter 3.7.5. #2000

Hey, All. We're migrating to Flutter 3.7.5. #2000

How to clone flutter of 3.7.5 version correctly?

[LucasXu0]

Here's an example. @leeyaal

# lucas.xu @ MacBook-Pro-6 in ~/Desktop/flutter on git:3.3.10 o [9:22:29] C:130
$ pwd
/Users/lucas.xu/Desktop/flutter

# lucas.xu @ MacBook-Pro-6 in ~/Desktop/flutter on git:3.3.10 o [9:22:30]
$ git checkout 3.3.10

[leeyaal]

Here's an example. @leeyaal

# lucas.xu @ MacBook-Pro-6 in ~/Desktop/flutter on git:3.3.10 o [9:22:29] C:130
$ pwd
/Users/lucas.xu/Desktop/flutter

# lucas.xu @ MacBook-Pro-6 in ~/Desktop/flutter on git:3.3.10 o [9:22:30]
$ git checkout 3.3.10

is it appropriate tu use
RUN git clone https://github.com/flutter/flutter.git --branch 3.7.5 $HOME/.local/flutter
in dockerfile?

[LucasXu0]

Yes. However, the migration PR doesn't be merged yet. The main branch only runs successfully with Flutter 3.3.10.

[leeyaal]

so we are waiting for migration? @LucasXu0
It does not work for me with 3.3.10
