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

import 'package:flutter/material.dart';

void main() {
  runApp(MaterialApp(home: const MyApp()));
}

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

  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  // 初始化选中的日期为当前日期
  DateTime _selectedDate = DateTime.now();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("滚动日期选择器示例"),
        centerTitle: true,
      ),
      body: Column(
        children: [
          // 显示当前选中的日期
          Container(
            height: 100.0,
            alignment: Alignment.center,
            child: Text(
              "$_selectedDate",
              style: TextStyle(fontSize: 20.0, fontWeight: FontWeight.w500),
            ),
          ),
          // 添加一个按钮，点击后设置当前日期为今天
          Container(
            alignment: Alignment.centerRight,
            padding: const EdgeInsets.only(right: 48),
            child: TextButton(
              onPressed: () {
                setState(() {
                  _selectedDate = DateTime.now();
                });
              },
              child: Text(
                "今天",
                style: TextStyle(color: Colors.red),
              ),
            ),
          ),
          // 使用ScrollDatePicker组件
          SizedBox(
            height: 250,
            child: ScrollDatePicker(
              // 设置初始选中的日期
              selectedDate: _selectedDate,
              // 设置最小可选日期
              minimumDate: DateTime(2017, 6, 6),
              // 设置语言环境
              locale: Locale('en'),
              // 监听日期变化
              onDateTimeChanged: (DateTime value) {
                setState(() {
                  _selectedDate = value;
                });
              },
            ),
          ),
        ],
      ),
    );
  }
}

代码解释

• _selectedDate: 用于存储用户选择的日期。
• setState: 用于更新UI状态，当日期发生变化时，UI会自动更新。
• ScrollDatePicker: 这个组件是主要的日期选择器组件。通过配置它的参数可以自定义日期选择器的行为和外观。
