Flutter獲取全局context

經過navigatorKey的方式

 

void main() {
  runApp(MyApp());
}
 
final GlobalKey<NavigatorState> navigatorKey = new GlobalKey<NavigatorState>();
 
class MyApp extends StatelessWidget {
  MyApp() {
  }
 
  // This widget is the view.common.root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      navigatorKey: navigatorKey,
    );
  }
}

獲取context:

BuildContext context = navigatorKey.currentState.overlay.context

注意：經過這種方式獲取的context在某些狀況下須要放在
Future.delayed(Duration(seconds: 0)).then((onValue) { });
