flutter, PageRouteBuilder, adding Horizontal Transition - flutter

Question

The native navigation transition for iOS is RightToLeft. The Native Navigation transition for ANDROID is Bottom to Top. I would like to override the Native Navigation transition in Flutter to have the same RIght to Left transtion across iOS and ANDROID. To do this, I am trying to use PageRouteBuilder but no luck getting it to work. The first code block, I have a very basic screen that works... but natively. The second snippet includes the navigation transition code I am attempting to integrate.
The Code I am trying to fix.
import 'package:flutter/material.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter Demo',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
home: new MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => new _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
#override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text(widget.title),
),
body: new Center(
child: new Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
//==============================================
// How would I force a horizontal transition?
mbNav001(context),
new Text(
'Screen 1',
),
],
),
),
);
}
}
//===================================================
Padding mbNav001(BuildContext context) {
return Padding(
padding: const EdgeInsets.all(28.0),
child: new MaterialButton(
height: 80.0,
padding: EdgeInsets.all(50.0),
minWidth: double.infinity,
color: Theme.of(context).primaryColor,
textColor: Colors.white,
child: new Text(
"material button a",
style: new TextStyle(
fontSize: 20.0,
color: Colors.yellow,
),
),
splashColor: Colors.redAccent,
// ----- This line is giving me error...
onPressed: () {
print('click mb');
//===========================================================
// How to force a horizontal trans in Navigation?
//===========================================================
Navigator.push(
context,
MaterialPageRoute(builder: (context) => SecondScreen()),
);
}
// expecting to find... :
),
);
}
//===================================================
class SecondScreen extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Second Screen"),
),
body: Center(
child: RaisedButton(
onPressed: () {
// Navigate back to first screen when tapped!
Navigator.pop(context);
},
child: Text('Go back!'),
),
),
);
}
}
this is the transition code I am trying to add.
transitionsBuilder: (
BuildContext context,
Animation<double> animation,
Animation<double> secondaryAnimation,
Widget child) {
return SlideTransition(
position: new Tween<Offset>(
begin: const Offset(1.0, 0.0),
end: Offset.zero,
).animate(animation),
child: new SlideTransition(
position: new Tween<Offset>(
begin: Offset.zero,
end: const Offset(1.0, 0.0),
).animate(secondaryAnimation),
child: child,
),
);
},
);
Navigator.of(context).push(pageRoute);

Answer 1

Using CupertinoPageRoute instead of MaterialPageRoute resolved the same issue in my case, without trying to apply any custom animation.
Navigator.of(context).push(CupertinoPageRoute(builder: (context) => MyPanel()));

Answer 2

This is the code i've used to achieve the slide up from the bottom animation on iOS. You'd just need to edit the tween values to achieve a left to right animation.
var builder = PageRouteBuilder(
pageBuilder: (BuildContext context,
Animation animation,
Animation secondaryAnimation) {
return YourChildWidgetHere();
},
transitionsBuilder: (
BuildContext context,
Animation<double> animation,
Animation<double> secondaryAnimation,
Widget child,
) {
return new SlideTransition(
position: new Tween<Offset>(
begin: const Offset(0.0, 1.0),
end: Offset.zero,
).animate(animation),
child: child,
);
});
Navigator.of(context).push(builder);
