0















When i use navigator nested in MaterialApp that contains a navigator, there is shadow as showed in the following image.



Why? How to remove this shadow?



enter image description here



My code is here:



import 'package:flutter/material.dart';

void main() => runApp(NavigatorNested());

class NavigatorNested extends StatefulWidget {
@override
NavigatorNestedState createState() => NavigatorNestedState();
}

class NavigatorNestedState extends State<NavigatorNested> {
@override
Widget build(BuildContext context) {
return MaterialApp(
initialRoute: 'hpme',
title: 'test',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: Scaffold(
appBar: AppBar(
title: Text('helle world'),
),
body: Container(
margin: EdgeInsets.symmetric(vertical: 48, horizontal: 24),
child: Navigator(
onGenerateRoute: (settings) {
return MaterialPageRoute<dynamic>(
settings: settings,
builder: (context) {
return Text('helle world');
});
},
onUnknownRoute: (settings) {
return MaterialPageRoute<dynamic>(
settings: settings,
builder: (context) {
return Text('helle world');
});
},
initialRoute: "home",
),
),
),
);
}
}


If i use Text('hello') to replace Navigator, it works goods. Is it a bug in flutrer?

          The MaterialPageRoute itself is a material widget, so it has an elevation and a shadow.



          Use PageRouteBuilder instead, this is the pageroute that does not contain the material effect. A good example is in the 'Custom route' section of Navigator documentation.



          Edit: sorry, it seems the example in the documentation does not fit into your scenario. You can use PageRouteBuilder like this



          Navigator(
          //...
          onGeneratedRoute: PageRouteBuilder(
          pageBuilder: //...
          transitionsBuilder: //There are some good examples about this transition animation on the web
          ),
          //...
          )
