我发现这部分:body: _items[_selectedIndex],在我的代码中使它发生。
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:surrfy/navbar_pages/favorites.dart';
import 'package:surrfy/navbar_pages/profile.dart';
class HomePage extends StatefulWidget {
const HomePage({Key? key}) : super(key: key);
@override
State<HomePage> createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
int _selectedIndex = 0;
void _navigatorBottomNavBar(int index) {
setState(() {
_selectedIndex = index;
});
}
final List<Widget> _items = [
HomePage(),
Favorites(),
Profiles(),
];
@override
Widget build(BuildContext context) {
return Scaffold(
body: _items[_selectedIndex],
bottomNavigationBar: BottomNavigationBar(
currentIndex: _selectedIndex,
onTap: _navigatorBottomNavBar,
type: BottomNavigationBarType.fixed,
items: [
BottomNavigationBarItem(icon: Icon(Icons.home, size: 35,), label: '',),
BottomNavigationBarItem(icon: Icon(Icons.favorite_outline, size: 35,), label: '',),
BottomNavigationBarItem(icon: Icon(Icons.person_outline_rounded, size: 35,), label: '',),
],
),
);
}
}
这是完整的代码。
我想做一个底部导航栏，当我按下图标时让页面改变，但是这个错误一直出现
你的代码生成了一个无限循环，在这里创建嵌套的主页小部件:身体:_items [_selectedIndex]
你可以更新_items变量来停止这个错误:
final List<Widget> _items = [
Text('Home Page'),
Favorites(),
Profiles(),
];
希望对你有帮助。
