flutter - 双击 TextFormField

问题描述

我使用颤振 1.17.0，但是当我在 TextFormField 中双击以将文本粘贴到 TextFormField 时，一件事并不好我收到此错误

我的 main.dart

void main() {
runApp(EasyLocalization(child: MyApp()));
}

class MyApp extends StatefulWidget {
@override
State createState() {
return _MyAppState();
}
}

class _MyAppState extends State {
final MainModel _model = MainModel();

@override
void initState() {
SystemChrome.setPreferredOrientations([

]);
_model.initAppDirectory();
super.initState();
}

changeStatusBar() async{
await FlutterStatusbarcolor.setStatusBarColor(MySetting.mainColor);
FlutterStatusbarcolor.setStatusBarWhiteForeground(true);
if(Theme.of(context).platform == TargetPlatform.android){
await FlutterStatusbarcolor.setNavigationBarColor(Colors.black38);
}
}

@override
Widget build(BuildContext context) {
changeStatusBar();
var data = EasyLocalizationProvider.of(context).data;

return ScopedModel<MainModel>(
    model: _model,
    child: ScopedModelDescendant<MainModel>(
      rebuildOnChange: false,
        builder: (BuildContext context, Widget child, MainModel model) {
      return EasyLocalizationProvider(
        data: data,
        child: FlutterEasyLoading(
          child: MaterialApp(
            builder: (BuildContext context, Widget child) {
              return MediaQuery(
              data: MediaQuery.of(context).copyWith(textScaleFactor: 1.0),
              child: child,
              );
            },
            debugShowCheckedModeBanner: false,
            title: 'my app',              
            localizationsDelegates: [
              GlobalCupertinoLocalizations.delegate,
              DefaultCupertinoLocalizations.delegate,
              GlobalMaterialLocalizations.delegate,
              GlobalWidgetsLocalizations.delegate,
              EasylocaLizationDelegate(
                  locale: Locale('ar', 'DZ'), path: 'assets/languages'),
            ],
            supportedLocales: [Locale('ar', 'DZ'), Locale('en', 'US')],
            locale: data.locale,
            theme: ThemeData(
              primarySwatch: MySetting.mainColor,
            ),
            home: SplashScreen( _model),
            },
          ),
        ),
      );
    }));
}
}

请任何帮助解决它，因为我的应用程序已停止解决此问题并且红屏错误仍然出现，我不知道错误在哪里
