先谢谢您。

如果您想在转到pushReplacement
时跳过页面,只需使用push
而不是back
。
import 'dart:math';
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter naviagtion',
theme: ThemeData(
backgroundColor: Colors.white,
primarySwatch: Colors.green,
),
home: DashboardLandingScreen(),
);
}
}
class DashboardLandingScreen extends StatelessWidget {
static Route route() => MaterialPageRoute(
builder: (context) => DashboardLandingScreen(),
);
@override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
alignment: Alignment.center,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('Dashboard landing screen.'),
RaisedButton(
child: Text('List of Topics'),
onPressed: () => Navigator.of(context).push(
TopicsListScreen.route(),
),
),
],
),
),
);
}
}
class TopicsListScreen extends StatelessWidget {
static Route route() => MaterialPageRoute(
builder: (context) => TopicsListScreen(),
);
@override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
alignment: Alignment.center,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('List of Topics'),
RaisedButton(
child: Text('Create New Topic'),
onPressed: () => Navigator.of(context).push(
NewTopic.route(),
),
),
],
),
),
);
}
}
class NewTopic extends StatelessWidget {
static Route route() => MaterialPageRoute(
builder: (context) => NewTopic(),
);
@override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
alignment: Alignment.center,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('page: new topic'),
RaisedButton(
child: Text('Save'),
onPressed: () => Navigator.of(context).pushReplacement(
CreatedTopicDetails.route(),
),
),
],
),
),
);
}
}
class CreatedTopicDetails extends StatelessWidget {
static Route route() => MaterialPageRoute(
builder: (context) => CreatedTopicDetails(),
);
@override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
alignment: Alignment.center,

}
