- Create a new Flutter application
- Creating a user interface
- Create a navigation
1. create a new project “Flutter
Let’s create a new Flutter application. If you don’t know how to create a project, you can look at the “Hello World App in Flutter” tutorial. For this tutorial, we will create two screens. One of the screens will be “Home”.
2. creating a user interface
We will create a very simple screen with a button in the middle. Below is sample code that does exactly that.
La classe Home étend StatefulWidget {@override_HomeState createState() => _HomeState() ; }
The class HomeState extends State {@overrideWidget
build(BuildContext context))
{ return
scaffold
(
appBar : AppBar(
title: const Text (“Move to a new screen when button is pressed”,)
color: colors.teal),
body: middle(
child : FlatButton(
color: colors.teal,
textColor: colors. White,
onPress: () {
},
child: text(‘SKIP TO SCREEN 2’),
)
,
}}
For the second screen, we use the same layout but change the colors. This way we can see if the navigation works.
Below is a sample code for screen 2.
La classe Screen2 étend le StatefulWidget {@override_Screen2State createState() => _Screen2State() ; }
The class _Screen2State extends State {@overrideWidget
build(BuildContext context))
{ return
scaffold
(
appBar: AppBar(
title: const Text(‘Go to a new screen when you press the button’,)
Color: blueAccent),
body: Center(
child: FlatButton(
color: Colors.blueAccent,
textColor: Colors. White,
onPress: () {
},
child: text(‘Go to HOME’),
)
;
}
2. create a navigation
The Flutter software has a built-in method for navigating between screens called “Navigator”. We will use the Navigator.push method to navigate to a new screen. The push() method adds the screen to the route stack managed by the Navigator. We will create our own route with MaterialPageRoute, which is useful because it jumps to the new route with platform-specific animations. Here is sample code for navigation:
FlatButton(
Farbe: Colors.teal,
textColor: Farben. Weiß,
overPress: ( ) {
Navigator.or(context).push(MaterialPageRoute(builder : (context)=>Screen2()); },
child : Text(‘GO TO SCREEN 2’),),
As you can see in the “onPressed” property, we have a function( Navigator.or(context).push(“MaterialPageRoute(builder) : (context)=>Screen2(); “) that takes us to the desired screen. Here is the code of the whole request :
import “package:flutter/material.dart” ;
void main() => runApp(MyApp()) ;
/// This widget is the main application widget.
The MyApp class extends the StatelessWidget {@overrideWidget
build(BuildContext context)) {
return MaterialApp(
home : Home(),)
;
}}
La classe Home étend StatefulWidget {@override_HomeState createState() => _HomeState() ; }
_HomeState class extends State {@overrideWidget
build(BuildContext context)) {return
Gerüst(
appBar : AppBar(
titre : const Texte (“Gehe zu neuem Bildschirm, wenn Taste gedrückt wird”),
Farbe : Colors.teal),
corps : centre(
enfant : FlatButton(
couleur : Colors.teal,
textColor : Farben. Weiß,
surPress : () {
Navigator.of(context).push(MaterialPageRoute(builder : (context)=>Screen2()) ; },enfant :
Text(‘GA NAAR SCREEN 2’)),),), }}}
klasse
Screen2 étend StatefulWidget {@override_Screen2State createState() => _Screen2State() ; }
The class _Screen2State extends State {@overrideWidget
build(BuildContext context))
{ return
scaffold
(
appBar: AppBar(
title: const Text(‘Go to a new screen when you press the button’,)
Color: blueAccent),
body: Center(
child: FlatButton(
color: Colors.blueAccent,
textColor: Colors. White,
hePress: () {
Navigator.or(context).push(MaterialPageRoute(builder : (context)=>Home())))
},
child: text(‘Go to HOME’),
)
;
}
