Want to show user-friendly error page instead of exception in Flutter. There is a little static error builder hidden in the documentation.
You can define in the the builder method of the MaterialApp widget.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | Widget buildError(BuildContext context, FlutterErrorDetails error) { return Scaffold( body: Center( child: Text( "Error appeared.", style: Theme.of(context).textTheme.title, ), ) ); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( theme: ThemeData( primarySwatch: Colors.blue, ), builder: (BuildContext context, Widget widget) { ErrorWidget.builder = (FlutterErrorDetails errorDetails) { return buildError(context, errorDetails); }; return widget; }, title: 'Flutter Demo', home: MyHomePage(title: 'Flutter Demo Home Page'), ); } } |
