void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}

primarySwatch: Colors.blue,
),
home: Scaffold(
appBar: AppBar(
title: Text('Example'),
),
backgroundColor: Colors.white,
body: Center(
child: HorizontalFeaturedList(
// 为每个项目设置颜色
itemColorBuilder: (context, index) => colors[index],
// 设置项目的数量
itemCount: colors.length,
// 创建每个项目的UI
itemBuilder: (BuildContext context, int index) {
return Column(
children: [
Row(
children: <Widget>[
// 显示图标
Icon(
Icons.face,
size: 24,
color: Colors.black45,
),
// 扩展区域以容纳文本

// 按钮点击事件(示例中未实现)
onPressedItem: () {},
// “查看所有”按钮点击事件(示例中未实现)
onPressedSeeAll: () {},
// 标题文本
titleText: 'Ongoing Projects',
// 查看所有按钮的文本
seeAllText: 'See All',
),
),
),
);
}
}
// 生成随机颜色
Color randomColor() {
var g = math.Random.secure().nextInt(255);
var b = math.Random.secure().nextInt(255);
var r = math.Random.secure().nextInt(255);
return Color.fromARGB(255, r, g, b);
}

当然,以下是如何在Flutter项目中使用flutter_horizontal_featured_list
插件来展示水平特色列表的示例代码。这个插件可以帮助你创建一个可滚动的水平列表,非常适合用于展示特色项目或产品。
首先,确保你已经在pubspec.yaml
文件中添加了flutter_horizontal_featured_list
插件的依赖:
dependencies:
flutter:
sdk: flutter
flutter_horizontal_featured_list: ^最新版本号 # 请替换为最新版本号
然后,运行flutter pub get
来安装依赖。
接下来,在你的Flutter项目中,你可以按照以下方式使用flutter_horizontal_featured_list
插件:
import 'package:flutter/material.dart';
import 'package:flutter_horizontal_featured_list/flutter_horizontal_featured_list.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Horizontal Featured List Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: HomeScreen(),
);
}
}
class HomeScreen extends StatelessWidget {
final List<FeaturedItem> featuredItems = [
FeaturedItem(
image: 'https://example.com/image1.jpg', // 替换为实际图片URL
title: 'Item 1',
description: 'Description for item 1',
),
FeaturedItem(
image: 'https://example.com/image2.jpg', // 替换为实际图片URL
title: 'Item 2',
description: 'Description for item 2',
),
// 添加更多项目...
];
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Horizontal Featured List'),
),
body: Padding(
padding: const EdgeInsets.all(16.0),
child: HorizontalFeaturedList(
featuredItems: featuredItems,
onItemClick: (index) {
// 单击项目时的回调,可以在这里处理点击事件
print('Item clicked: $index');
// 例如,可以导航到另一个页面
// Navigator.push(context, MaterialPageRoute(builder: (context) => DetailScreen(item: featuredItems[index])));
},
),
),
);
}
}
// FeaturedItem类定义,根据插件的API可能需要调整
class FeaturedItem {
String image;
String title;
String description;
FeaturedItem({required this.image, required this.title, required this.description});
}
在这个示例中,我们创建了一个简单的Flutter应用,其中包含一个水平特色列表。HorizontalFeaturedList
组件接受一个featuredItems
列表,每个项目都是一个FeaturedItem
对象,包含图像URL、标题和描述。当用户点击某个项目时,onItemClick
回调函数会被调用,你可以在这里处理点击事件,比如导航到另一个页面。
请注意,FeaturedItem
类的定义可能需要根据flutter_horizontal_featured_list
插件的实际API进行调整。另外,如果插件需要额外的配置或方法,请参考其官方文档。
希望这个示例能帮助你成功地在Flutter项目中集成和使用flutter_horizontal_featured_list
插件!
