新建文件:lib/pages/home_page.dart
dart
import 'package:flutter/material.dart';
class HomePage extends StatefulWidget {
const HomePage({super.key});
@override
State<HomePage> createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
// 当前选中的底部导航索引
int _selectedIndex = 0;
// 轮播图数据(模拟)
final List<Map<String, dynamic>> _banners = [
{'color': Colors.orange.shade400, 'text': '限时特惠'},
{'color': Colors.blue.shade400, 'text': '新品上市'},
{'color': Colors.green.shade400, 'text': '热卖推荐'},
];
// 商品分类数据(10个,还原设计图)
final List<Map<String, dynamic>> _categories = [
{'name': '数码', 'icon': Icons.phone_android, 'color': Colors.blue},
{'name': '服饰', 'icon': Icons.checkroom, 'color': Colors.purple},

{"name": "鸿蒙旗舰手机", "price": "3999", "sales": "2311"},
{"name": "无线蓝牙耳机", "price": "399", "sales": "1202"},
{"name": "智能手表", "price": "1299", "sales": "890"},
{"name": "平板电脑", "price": "2999", "sales": "1567"},
];
// 底部导航点击事件
void _onItemTapped(int index) {
setState(() {
_selectedIndex = index;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
// 主体内容(可滚动,防止溢出)
body: SingleChildScrollView(
child: Column(
children: [
// 1️⃣ 顶部渐变搜索栏 🔥
_buildSearchHeader(),
// 2️⃣ 轮播Banner区域 📢
_buildBanner(),
// 3️⃣ 商品分类网格 📦
_buildCategoryGrid(),
// 4️⃣ 为你推荐商品列表 🛒
_buildRecommendSection(),
],
),
),
// 5️⃣ 底部导航栏 🧭
bottomNavigationBar: _buildBottomNav(),
);
}
1️⃣ 顶部渐变搜索栏(城市+搜索框+相机)
dart
// 顶部搜索栏

return Container(
width: double.infinity,
padding: const EdgeInsets.fromLTRB(15, 40, 15, 20),
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [Colors.orangeAccent, Colors.orange],
begin: Alignment.topCenter,
end: Alignment.bottomCenter,
),
),
child: Row(
children: [
// 城市选择
Row(
children: const [
Text(
"深圳",
style: TextStyle(color: Colors.white, fontSize: 16),
),
Icon(Icons.arrow_drop_down, color: Colors.white),
],

const SizedBox(width: 10),
// 搜索框
Expanded(

color: Colors.white,
borderRadius: BorderRadius.circular(20),
),

children: const [
Icon(Icons.search, color: Colors.grey),
SizedBox(width: 5),
Text("搜索商品", style: TextStyle(color: Colors.grey)),
],

),
),
const SizedBox(width: 10),
// 相机图标
const Icon(Icons.camera_alt, color: Colors.white),

),
);
}
2️⃣ 轮播Banner区域(渐变+优惠标签)
dart
// 轮播图
Widget _buildBanner() {
return Container(
height: 160,
margin: const EdgeInsets.all(15),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(15),
gradient: LinearGradient(
colors: [Colors.orangeAccent, Colors.orange],
),
),
child: Stack(
children: [
const Positioned(
left: 20,
top: 30,
child: Text(
"限时特惠\n新人专享优惠",
style: TextStyle(color: Colors.white, fontSize: 18, height: 1.5),

Positioned(

top: 20,
child: Container(
width: 80,
height: 80,
decoration: const BoxDecoration(
color: Colors.white12,
shape: BoxShape.circle,
),
child: const Icon(Icons.shopping_bag, color: Colors.white, size: 40),
),
),
],
),
);
}
3️⃣ 商品分类网格(10个分类+图标)
dart
// 分类网格
Widget _buildCategoryGrid() {
return GridView.builder(
shrinkWrap: true,
physics: const NeverScrollableScrollPhysics(),
padding: const EdgeInsets.symmetric(horizontal: 15),
gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 5,
crossAxisSpacing: 5,
mainAxisSpacing: 15,
childAspectRatio: 1,
),
itemCount: _categories.length,
itemBuilder: (context, index) {
var item = _categories[index];
return Column(
children: [
Container(
width: 50,
height: 50,
decoration: BoxDecoration(
color: item['color'].withOpacity(0.1),
borderRadius: BorderRadius.circular(10),
),
child: Icon(item['icon'], color: item['color']),
),
const SizedBox(height: 5),
Text(item['name'], style: const TextStyle(fontSize: 12)),
],
);
},
);
}
4️⃣ 为你推荐商品(双列网格+销量+价格)
dart

children: [
const Text(
"为你推荐",
style: TextStyle(fontSize: 16, fontWeight: FontWeight.bold),
),
const SizedBox(height: 15),
GridView.builder(
shrinkWrap: true,
physics: const NeverScrollableScrollPhysics(),
gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
crossAxisCount: 2,
crossAxisSpacing: 10,
mainAxisSpacing: 10,
childAspectRatio: 0.75,
),
itemCount: _products.length,
itemBuilder: (context, index) {
var product = _products[index];
return Container(
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(10),
boxShadow: [
BoxShadow(
color: Colors.grey.withOpacity(0.1),
blurRadius: 3,
),
],
),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
// 商品图片占位
Container(
height: 120,
decoration: BoxDecoration(
color: Colors.grey[100],
borderRadius: const BorderRadius.vertical(top: Radius.circular(10)),
),
child: const Center(child: Icon(Icons.image, color: Colors.grey)),
),
Padding(
padding: const EdgeInsets.all(8),
child: Text(
product['name'],
maxLines: 2,
overflow: TextOverflow.ellipsis,

),
),
],
),
);
},
),
],
),
);
}
5️⃣ 底部导航栏(首页/分类/购物车/我的)
dart
// 底部导航
Widget _buildBottomNav() {
return BottomNavigationBar(
items: const [
BottomNavigationBarItem(icon: Icon(Icons.home), label: '首页'),
BottomNavigationBarItem(icon: Icon(Icons.category), label: '分类'),
BottomNavigationBarItem(icon: Icon(Icons.shopping_cart), label: '购物车'),
BottomNavigationBarItem(icon: Icon(Icons.person), label: '我的'),
],
currentIndex: _selectedIndex,
selectedItemColor: Colors.orange,
unselectedItemColor: Colors.grey,
type: BottomNavigationBarType.fixed,
onTap: _onItemTapped,

}
}
✅ 运行方法(3秒搞定)
- 在项目
lib/pages/下新建home_page.dart - 复制全部代码进去
- 在路由中跳转到该页面
- 运行在鸿蒙模拟器/真机
- 效果直接拉满🎉

💡 鸿蒙适配避坑指南(大学生必看)
我实战踩过的坑😭,直接帮你避开:
- 页面溢出报错
✅ 解决方案:外层套SingleChildScrollView - 网格列表卡顿
✅ 解决方案:shrinkWrap: true+NeverScrollableScrollPhysics - 鸿蒙状态栏文字看不清
✅ 解决方案:使用渐变背景+白色文字对比 - 底部导航被键盘顶起
✅ 解决方案:Flutter原生已自动适配,直接用
