推荐答案
您可以通过使用 CupertinoPageRoute.请检查以下代码.
You can achieve this by using CupertinoPageRoute. Please check the below code.
import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Transition Animation Demo',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
home: new FirstPage(),
);
}
}
class FirstPage extends StatefulWidget {
@override
_FirstPageState createState() => new _FirstPageState();
}
class _FirstPageState extends State<FirstPage> {
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text('First Page'),
),
body: new Center(
child: new RaisedButton(
child: new Text('Goto Second Page'),
onPressed: () {
Navigator.of(context).push(new SecondPageRoute());
},
),
),
);
}
}
class SecondPageRoute extends CupertinoPageRoute {
SecondPageRoute()
: super(builder: (BuildContext context) => new SecondPage());
// OPTIONAL IF YOU WISH TO HAVE SOME EXTRA ANIMATION WHILE ROUTING
@override
Widget buildPage(BuildContext context, Animation<double> animation,
Animation<double> secondaryAnimation) {
return new FadeTransition(opacity: animation, child: new SecondPage());
}
}
class SecondPage extends StatefulWidget {
@override
_SecondPageState createState() => new _SecondPageState();
}
class _SecondPageState extends State<SecondPage> {
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text('Second Page'),
),
body: new Center(
child: new Text('This is the second page'),
),
);
}
}
一些动画游戏
// OPTIONAL IF YOU WISH TO HAVE SOME EXTRA ANIMATION WHILE ROUTING
@override
Widget buildPage(BuildContext context, Animation<double> animation,
Animation<double> secondaryAnimation) {
return new RotationTransition(
turns: animation,
child: new ScaleTransition(
scale: animation,
child: new FadeTransition(
opacity: animation,
child: new SecondPage(),
),
));
}
