在MyApp 类中自定义错误页面
Widget getErrorWidget(BuildContext context, FlutterErrorDetails error) {
return Center(
child: Text(
"Error appeared.",
style: Theme.of(context).textTheme.title.copyWith(color: Colors.red),
),
);
}
然后在build(BuildContext context)中添加
ErrorWidget.builder = (FlutterErrorDetails errorDetails) {
return getErrorWidget(context, errorDetails);
};
//事例
class MyApp extends StatelessWidget {
Widget getErrorWidget(BuildContext context, FlutterErrorDetails error) { return Center( child: Text( "Error appeared.", style: Theme.of(context).textTheme.title.copyWith(color: Colors.red), ), ); }
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
ErrorWidget.builder = (FlutterErrorDetails errorDetails) { return getErrorWidget(context, errorDetails); };
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
// This is the theme of your application.
//
// Try running your application with "flutter run". You'll see the
// application has a blue toolbar. Then, without quitting the app, try
// changing the primarySwatch below to Colors.green and then invoke
// "hot reload" (press "r" in the console where you ran "flutter run",
// or simply save your changes to "hot reload" in a Flutter IDE).
// Notice that the counter didn't reset back to zero; the application
// is not restarted.
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
