Navigate to a new screen in Flutter - dart

Question

How do you navigate to a new screen in Flutter?
These questions are similar, but are asking more than I am.

Answer 1

Navigate to a new screen:
Navigator.of(context).push(MaterialPageRoute(builder: (context) => NewScreen()));
where context is the BuildContext of a widget and NewScreen is the name of the second widget layout.
Code
main.dart
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(primarySwatch: Colors.blue),
home: HomeScreen(),
);
}
}
class HomeScreen extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: const Text('Home Screen')),
body: Center(
child: ElevatedButton(
child: const Text(
'Navigate to a new screen >>',
style: TextStyle(fontSize: 24.0),
),
onPressed: () {
_navigateToNextScreen(context);
},
),
),
);
}
void _navigateToNextScreen(BuildContext context) {
Navigator.of(context).push(MaterialPageRoute(builder: (context) => NewScreen()));
}
}
class NewScreen extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: const Text('New Screen')),
body: const Center(
child: Text(
'This is a new screen',
style: TextStyle(fontSize: 24.0),
),
),
);
}
}

To load new screens with Flutter pre-canned animations, use their respective transition classes. For example:
Container Transformation
Basically we have the first widget or screen transform into the next screen. For this we need to use OpenContainer. The following code illustrates an item in a ListView transformed to its details page.
#override
Widget build(BuildContext context) {
return Card(
color: Colors.white,
elevation: 2.0,
child: OpenContainer(
transitionType: ContainerTransitionType.fadeThrough,
closedColor: Theme.of(context).cardColor,
closedElevation: 0.0,
openElevation: 4.0,
transitionDuration: Duration(milliseconds: 1500),
openBuilder: (BuildContext context, VoidCallback _) => THENEXTSCREEN(),
closedBuilder: (BuildContext _, VoidCallback openContainer) {
return ListTile(
leading: Icon(Icons.album),
title: Text("ITEM NAME"),
);
},
),
);
}
Shared Axis
This transition is similar to that in Tab or Stepper. We need SharedAxisTransition, PageTransitionSwitcher, along with a state to model transition between active and previous page. If we only switch between two pages we can use a simple boolean isFirstPage for it. Here's the snippet with Provider as state management:
#override
Widget build(BuildContext context) {
return Consumer<YourState>(
builder: (context, state, child) {
return PageTransitionSwitcher(
duration: const Duration(milliseconds: 1500),
reverse: !state.isFirstPage, // STATE
transitionBuilder: (
Widget child,
Animation<double> animation,
Animation<double> secondaryAnimation,
) {
return SharedAxisTransition(
child: child,
animation: animation,
secondaryAnimation: secondaryAnimation,
transitionType: SharedAxisTransitionType.horizontal,
);
},
child: state.isFirstPage? FIRSTPAGE() : SECONDPAGE(), // STATE
);
},
);
}
Note that in all these scenarios we don't use Navigator and MaterialPageRoute. All these codes are derived from animations repo so you may want to check it out first.

Answer 3

Navigate to next screen with back using Navigator.push()
Navigator.push(
context,
MaterialPageRoute(builder: (context) => SecondRoute()),);
Navigate to next screen without back using Navigator.pushReplacement()
Navigator.pushReplacement(
context,MaterialPageRoute(builder: (context) => SecondRoute()),);

Answer 4

onTap: () {
Navigator.push(context,
MaterialPageRoute(builder: (context) => NextScreenName()));
}

Answer 5

If you are familiar with web development this approach is similar to routing.
main.dart
void main() {
setupLocator();
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
routes: {
'/' : (BuildContext context)=>HomePage(),
'/register' : (BuildContext context)=>RegisterPage(),
},
);
}
}
You can add button onPressed event from the homepage.dart to navigate register.dart as follows.
onPressed: (){
Navigator.pushReplacementNamed(context, '/register');
},

Answer 6

Here is a full example of routes push / pop:
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Routes',
routes: {
'/login': (BuildContext context) => Login(),
// add another route here
// '/register': (BuildContext context) => Register(),
},
theme: ThemeData(
primarySwatch: Colors.blue,
visualDensity: VisualDensity.adaptivePlatformDensity,
),
home: MyHomePage(title: 'Flutter Routes'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
RaisedButton(
onPressed: () {
// This gives the back button:
Navigator.of(context).pushNamed('/login');
// This doesn't give the back button (it replaces)
//Navigator.pushReplacementNamed(context, '/login');
},
child: Text('Login'),
),
],
),
),
);
}
}
class Login extends StatefulWidget {
#override
_LoginState createState() => _LoginState();
}
class _LoginState extends State<Login> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Login Page'),
),
body: Center(
child: RaisedButton(
onPressed: () {
// This will only work for pushNamed
Navigator.of(context).pop();
},
child: Text('Go back'),
),
));
}
}

Answer 7

you can use that way in your build widget
onTap: () { Navigator.of(context).push(MaterialPageRoute( builder: (context) => NewScreen()));},

Answer 8

In formal method :
Navigator.push(context, MaterialPageRoute(builder: (context)=>Second()));
In GetX method :
Get.to(Second());
If we can navigate screen into another page and delete current page from stack then we can use method which is define below :
Get.off(Third());
If we can navigate screen into another page and delete all route or page from stack then we can use the method which is define below :
Get.offAll(Third());
If we want to use Navigator.pop() then GetX give a Method which is define below :
Get.back();

Answer 9

You can try with the following code
Navigator.pushReplacement(context, MaterialPageRoute(builder: (context) => YourNextScreen())),

Answer 10

I found a good tutorial that I have followed along, it is very comprehensive with screenshots and step by step, you can also download the code and just run it. Very helpful for me learning Flutter especially I am totally a begineer.

Answer 11

With the Get plugin, you can navigate to a new page by simply calling
Get.to(Page());

Answer 12

This way you can present the next screen
Navigator.of(context).push(
MaterialPageRoute(fullscreenDialog: true,
builder: (context) => const NewScreen(),
),
);

Answer 13

FloatingActionButton(
onPressed: (){
Navigator.of(context).push(MaterialPageRoute(builder: (context) => const AddUser()));
},
child: const Icon(Icons.add),
),
