BUG: super_clipboard Cause PlatformException(channel-error, Unable to establish connection on channel., null, null) on Android devices

[EMUNES]

I found this exception always occur on Android devices, if I use super_clipboard (or packages depending on super_clipboard, like flutter_quill) with shared_preferences package. I can use shared_preference with other dozens of packages, but once with super_clipboard, the exception occurs which I can not get rid of. I report this BUG here because this is the only platform-related package I can find to cause this problem.

This exception will cause Android app unable to open. The app will hang.

This exception won't occur on Windows11 build. It won't occur if super_clipboard is the only package dependency.

ENV: flutter version: 3.19.6 and dart 3.3.4, Windows 11 VERSION: supper_clipboard 0.7.3 up to 0.8.12

Minimal code for reproduce:

pubspec.yml:

name: fix
description: "A new Flutter project."
publish_to: "none"
version: 1.0.0+1

environment:
  sdk: ">=3.3.4 <4.0.0"

dependencies:
  flutter:
    sdk: flutter
  shared_preferences: ^2.2.3 # Persistent settings.
  # flutter_quill: "9.0.0"
  super_clipboard: "0.7.3" # up to "8.0.12"
  # flutter_keyboard_visibility: ^6.0.0 # no problem.
  # url_launcher: ^6.2.6 # no problem.
  # device_info_plus: ^10.1.0 # no problem.

dev_dependencies:
  flutter_test:
    sdk: flutter

flutter:
  uses-material-design: true

Main code to run:

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:shared_preferences/shared_preferences.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  final prefs = await SharedPreferences.getInstance(); // Exception here.

  runApp(const MyApp());
}

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Container();
  }
}

降级这个依赖可以编译运行 Downgrade this dependency to compile and run

我还卸载了 rust. I also uninstalled rust.

flutter.ndkVersion: 23.1.7779620 cmdline-tools: latest

dependency_overrides:
  irondash_engine_context: 0.5.1

[EMUNES]

Sorry in my case, simply downgrading irondash_engine_context does not work. I didn't uninstall rust, because we need it in our environment.

Can you post here verbose log from flutter build?

[EMUNES]

Sure

The exception always occurs after building .apk. Then the app will hang and not open on Android.

[TabooSun]

I believe this is caused by my reported bug #352

[knopp]

This indeed looks like a duplicate of https://github.com/superlistapp/super_native_extensions/issues/352. I'll see if I can reproduce this. Could be a change in recent Rust.

[EMUNES]

This problem occurs after we upgrade flutter to 3.19.6 and rust from 1.77 to 1.78. So yes, it could be a rust problem instead.

[knopp]

Thanks for confirmation. There does seem to be a change of behavior where 1.78 links eh_personality for unoptimized no-std build for some reason. This should be fixed by https://github.com/irondash/irondash/pull/51.

[EMUNES]

Not waiting for merging, I have cloned irondash repo and tried this fix locally. The exception is finally gone, and the app runs normally on Android devices.

Thanks for working on this! Feel free to close this issue, after the fix is merged or not.
