类"图标"没有未命名的构造函数

Question

遇到此错误时，我一直在尝试构建底部导航栏。这是代码

import 'package:flutter/material.dart';
class NavPage extends StatefulWidget {
const NavPage({Key? key}) : super(key: key);
@override
State<NavPage> createState() => _NavPageState();
}
class _NavPageState extends State<NavPage> {
@override
Widget build(BuildContext context) {
return Scaffold(
bottomNavigationBar: BottomNavigationBar(
items: [
BottomNavigationBarItem(icon: Icons(Icons.local_movies),
activeIcon: const Icon(Icons.local_movies),
label: 'Movies'
),
],
),
);
}
}

Answer 1

您在这里输入错误，请使用Icon()获取构造函数。

BottomNavigationBarItem(icon: Icon(Icons.local_movies),

Answer 2

将其更改为：

BottomNavigationBarItem(icon: Icon(Icons.local_movies),
