How to change navigation animation using Flutter - animation

Question

Is there any way to change the default animation when navigating to/from a page in Flutter?

Answer 1

You can use PageRouteBuilder.
The following example shows FadeTransition when you navigate to second screen.
Navigator.push(
context,
PageRouteBuilder(
pageBuilder: (_, __, ___) => Page2(),
transitionDuration: Duration(seconds: 2),
transitionsBuilder: (_, a, __, c) => FadeTransition(opacity: a, child: c),
),
);
If you're using go_router:
GoRoute(
path: '/page2',
pageBuilder: (_, state) {
return CustomTransitionPage(
key: state.pageKey,
child: Page2(),
transitionDuration: Duration(seconds: 2),
transitionsBuilder: (_, a, __, c) => FadeTransition(opacity: a, child: c),
);
},
)
and then:
context.go('/page2');

You can subclass MaterialPageRouteand override buildTransitions.
Eg:
class MyCustomRoute<T> extends MaterialPageRoute<T> {
MyCustomRoute({ WidgetBuilder builder, RouteSettings settings })
: super(builder: builder, settings: settings);
#override
Widget buildTransitions(BuildContext context,
Animation<double> animation,
Animation<double> secondaryAnimation,
Widget child) {
if (settings.isInitialRoute)
return child;
// Fades between routes. (If you don't want any animation,
// just return child.)
return new FadeTransition(opacity: animation, child: child);
}
}
to use :
new RaisedButton(
child: new Text('Goto'),
onPressed: (){
Navigator.push(
context,
new MyCustomRoute(builder: (context) => new SecondPage()),
);
}),
Replace fade transition with your animation

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'),
),
);
}
}
Some play-around with animation
// 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(),
),
));
}

I have done this by providing my own builders with custom map in pageTransitionsTheme for the app level theme.
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Startup Name Generator Tile',
home: RandomWords(),
theme: new ThemeData(
primaryColor: Colors.white,
// Add the line below to get horizontal sliding transitions for routes.
pageTransitionsTheme: PageTransitionsTheme(builders: {TargetPlatform.android: CupertinoPageTransitionsBuilder(),}),
),
);
}
}
Of course, I didn't add a map entry for ios as I use only android for TargetPlatform.

You can also check out page_transition package from https://pub.dev/packages/page_transition. This package contains the following different transitions.
fade,
rightToLeft,
leftToRight,
upToDown,
downToUp,
scale (with alignment),
rotate (with alignment),
size (with alignment),
rightToLeftWithFade,
leftToRightWithFade

Answer 6

the simplest way I figured, is to use MaterialPageRoute normally just add: fullscreenDialog: true, inside MaterialPageRoute()
