下面是一个完整的示例代码，展示了如何在一个 Flutter 应用中使用 rating_bar_swipe 插件。

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

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: '评分滑动插件演示',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

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

  final String title;

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

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

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text(
              '你已经点击了按钮次数：',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          Navigator.pushReplacement(
            context,
            MaterialPageRoute(
              builder: (BuildContext context) {
                return Rating(
                  functionUpdateRating: (value) {
                    print('当前评分: $value');
                  },
                  iterativeValue: 0.1,
                  initialRating: 0,
                  isVertical: Axis.horizontal,
                  itemSize: 40,
                );
              },
            ),
          );
        },
        tooltip: '增加计数',
        child: const Icon(Icons.add),
      ),
    );
  }
}
