Waiting for a new connection from Flutter on sdk gphone64 x86 64...
Error connecting to the service protocol: Exception: connection to device ended too early

Main函数代码 #

const bool useEmulator = false;
void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  try {
    await Firebase.initializeApp().then((value) => print(value));
    if (useEmulator == true) {
      await _connectToFirebaseEmulator();
      await FirebaseAppCheck.instance
          .activate(androidProvider: AndroidProvider.debug);
    }

    runApp(const MyApp());
  } catch (error) {
    print('setup has failed\n $error');
  }
}

已尝试的解决方法 #

• flutter clean
• flutter upgrade

解决方案建议 #

1. 优化Firebase初始化逻辑 #

Hot Restart会重新执行main函数，重复初始化Firebase可能导致引擎状态冲突。修改初始化逻辑，确保仅在未初始化时执行：

const bool useEmulator = false;
void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  try {
    // 检查Firebase是否已初始化，避免重复操作
    if (Firebase.apps.isEmpty) {
      await Firebase.initializeApp();
    }
    if (useEmulator == true) {
      await _connectToFirebaseEmulator();
      await FirebaseAppCheck.instance
          .activate(androidProvider: AndroidProvider.debug);
    }

    runApp(const MyApp());
  } catch (error) {
    print('setup has failed\n $error');
  }
}

2. 重置模拟器状态 #

模拟器的缓存或异常状态可能导致Hot Restart失败：

• 关闭当前模拟器，重新启动
• 执行模拟器出厂重置：进入模拟器的设置 > 系统 > 重置选项 > 清除所有数据（恢复出厂设置），之后重新运行应用

3. 检查插件兼容性 #

确保pubspec.yaml中Firebase相关插件版本与Flutter 3.13.8兼容，更新插件至最新稳定版后执行flutter pub get

4. 禁用DevTools运行 #

尝试不启动DevTools运行应用，排查是否是DevTools连接导致的问题：

flutter run --no-devtools

5. 切换至真机测试 #

如果模拟器持续出现问题，使用Android真机测试，确认是否是模拟器环境的问题
