Flutter无context页面跳转及获取全局context

通过navigatorKey的方式 

void main() {
  runApp(MyApp());
}

final GlobalKey navigatorKey = new GlobalKey();

class MyApp extends StatelessWidget {
  MyApp() {
  }

  // This widget is the view.common.root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      navigatorKey: navigatorKey,
    );
  }
}

跳转：

navigatorKey.currentState.pushName('跳转url') 

fluro跳转：

        AppRouteMatch match = router.match(path);
        AppRoute route = match?.route;
        Handler handler = route.handler;
        Map> parameters = match?.parameters ?? >{};
        navigatorKey.currentState.push(CupertinoPageRoute(builder: (BuildContext context) => handler.handlerFunc(context, parameters)));

获取context:

 Context context = navigatorKey.currentState.overlay.context

注意：通过这种方式获取的context在某些情况下需要放在

Future.delayed(Duration(seconds: 0)).then((onValue) {
});

中使用。
