基本使用：
import 'package:flutter/material.dart';
class TabBarControllerPage extends StatefulWidget {
TabBarControllerPage({Key key}) : super(key: key);
_TabBarControllerPageState createState() => _TabBarControllerPageState();
}
class _TabBarControllerPageState extends State<TabBarControllerPage> with SingleTickerProviderStateMixin{
TabController _tabController;
@override
void dispose(){ //生命周期函数：
super.dispose();
_tabController.dispose();
}
@override
void initState(){ //生命周期函数：
super.initState();
_tabController=new TabController(
vsync: this,
length:
);
_tabController.addListener((){
print(_tabController.index);
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('TabBarControllerPage'),
bottom: TabBar(
controller:this._tabController,
tabs: <Widget>[
Tab(text: '热销'),
Tab(text: '推荐')
],
),
),
body: TabBarView(
controller: this._tabController,
children: <Widget>[
Center(child: Text('热销')),
Center(child: Text('推荐'))
],
)
);
}
}
