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

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Scrollable Text Indicator Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Scrollable Text Indicator Demo'),
    );
  }
}

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

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Column(
        crossAxisAlignment: CrossAxisAlignment.stretch,
        children: [
          const Text(
            'Text title',
            style: TextStyle(
              fontSize: 22.0,
              color: Colors.black,
            ),
          ),
          const SizedBox(
            height: 16.0,
          ),
          Flexible(
            child: ScrollableTextIndicator(
              text: const Text(
                'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam pulvinar risus sit amet augue viverra ultrices. Aliquam erat volutpat. Proin sagittis ultricies blandit. Donec diam velit, vestibulum commodo leo eu, suscipit condimentum ante. Aenean laoreet sapien mauris. Praesent maximus sagittis felis auctor facilisis. In ullamcorper velit id leo semper, pellentesque luctus risus efficitur. Aenean et tristique diam, vitae volutpat mi. Morbi bibendum ut nibh a ornare. Nulla nec dolor pellentesque, gravida neque ut, condimentum augue. Phasellus mollis metus ac tincidunt venenatis. Aenean at ullamcorper massa. Vestibulum volutpat nunc ut ultrices facilisis. Cras dui lorem, vehicula eu hendrerit non, sollicitudin quis libero. Morbi dapibus libero tincidunt lobortis efficitur.',
                style: TextStyle(
                  color: Colors.black,
                  fontSize: 16.0,
                ),
              ),
              indicatorColor: Colors.blue, // 设置指示器颜色
              indicatorWidth: 3.0, // 设置指示器宽度
              spacing: 8.0, // 设置文本与指示器之间的间距
            ),
          ),
        ],
      ),
    );
  }
}

在这个示例中，我们创建了一个包含标题和可滚动文本的应用程序。通过设置 ScrollableTextIndicator 的属性，我们可以自定义指示器的颜色、宽度以及文本与指示器之间的间距等。
