  • 在同一个评分条中可以根据位置使用不同的小部件
AwesomeStarRating(
  starCount: 5,
  rating: 5.0,
  size: 30.0,
  color: Colors.orange,
  borderColor: Colors.orange,
),


AwesomeStarRating(
  starCount: 5,
  rating: 5.0,
  size: 30.0,
  onRatingChanged: (double value) {
    setState(() {
      rating = value;
    });
  },
  color: Colors.orange,
  borderColor: Colors.orange,
),

以下是一个完整的 Flutter 应用程序示例，展示了如何使用 awesome_rating 插件。

import 'package:flutter/material.dart';
import 'package:awesome_rating/awesome_rating.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Awesome rating',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Awesome rating Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),

当然，以下是如何在Flutter项目中使用awesome_rating插件的一个示例代码案例。这个插件允许用户通过简单的点击或滑动来给出评分。

步骤 1: 添加依赖

首先，在你的pubspec.yaml文件中添加awesome_rating依赖：

dependencies:
  flutter:
    sdk: flutter
  awesome_rating: ^0.0.6  # 请注意版本号，使用最新版本

然后运行flutter pub get来安装依赖。

步骤 2: 导入包

在你的Dart文件中导入awesome_rating包：

import 'package:awesome_rating/awesome_rating.dart';
import 'package:flutter/material.dart';

步骤 3: 使用AwesomeRating

下面是一个完整的示例，展示了如何在Flutter应用中使用AwesomeRating组件：

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _rating = 0;

  void _onRatingChanged(int rating) {
    setState(() {
      _rating = rating;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Awesome Rating Example'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            AwesomeRating(
              rating: _rating,
              allowHalfRating: true, // 是否允许半星评分
              minRating: 1, // 最小评分
              maxRating: 5, // 最大评分
              size: 30, // 星形图标的大小
              color: Colors.amber, // 未选中星形的颜色
              borderColor: Colors.grey, // 星形边框的颜色
              borderWidth: 2.0, // 星形边框的宽度
              spacing: 5.0, // 星形之间的间距
              listener: (rating, gesture) {
                // 当评分改变时调用的回调函数
                _onRatingChanged(rating);
              },
            ),
            SizedBox(height: 20),
            Text('Your Rating: $_rating'),
          ],
        ),
      ),
    );
  }
}

解释

  1. 依赖添加：在pubspec.yaml中添加awesome_rating依赖。
  2. 导入包：在Dart文件中导入awesome_rating包。
  3. 使用组件：
    • AwesomeRating组件接受多个参数，包括当前评分(rating)、是否允许半星评分(allowHalfRating)、最小和最大评分(minRating和maxRating)、星形图标的大小(size)、颜色(color)、边框颜色(borderColor)和宽度(borderWidth)、星形之间的间距(spacing)以及一个监听器(listener)。
    • 当评分改变时，listener回调被触发，你可以在这里更新UI或执行其他逻辑。

以上代码展示了如何在Flutter应用中使用awesome_rating插件来收集用户的评分。你可以根据需要调整参数和样式。
