1扯躺、mian.dart
import 'package:flutter/material.dart';
import 'package:jifeng/my_app.dart';
import './my_app.dart';
void main() => runApp(MyApp());
2捉兴、my_app.dart
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:jifeng/splash/splash_screen.dart';
import 'home/index_page.dart';
class MyApp extends StatelessWidget{
@override
Widget build(BuildContext context){
return MaterialApp(
title: 'loins',
theme: ThemeData(
primaryColor: Colors.black,
),
home: SplashScreen(),
routes: <String,WidgetBuilder>{
'/IndexPage':(context) => IndexPage()
},
);
}
}
3、splash_screen.dart
import 'package:flutter/material.dart';
import 'package:flutter/widgets.dart';
import 'dart:async';
class SplashScreen extends StatefulWidget {
@override
_SplashScreenState createState() => _SplashScreenState();
}
class _SplashScreenState extends State<SplashScreen>{
@override
Widget build(BuildContext context){
return Container(
color: Colors.white,
child: Image.network('http://img.zcool.cn/community/01a99d5542ea730000019ae9cf7739.jpg@1280w_1l_2o_100sh.png',fit: BoxFit.cover,),
);
}
@override
void initState() {
// TODO: implement initState
super.initState();
countDown();
}
void countDown(){
var _duration = Duration(seconds: 4);
Future.delayed(_duration,_indexPage);
}
void _indexPage(){
Navigator.of(context).pushReplacementNamed('/IndexPage');
}
}
4录语、index_page.dart
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
class IndexPage extends StatelessWidget{
@override
Widget build(BuildContext context) {
// TODO: implement build
return Scaffold(
appBar: AppBar(
title: Text('splash'),
centerTitle: true,
),
body: Center(
child: Text('案例',style:Theme.of(context).textTheme.display2,),
),
);
}
}
