如何在flutter中填充复选框内的颜色？

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Custom Checkbox Color'),
        ),
        body: Center(
          child: CheckboxListTile(
            value: false,
            onChanged: (bool? value) {
              // Handle checkbox change
            },
            activeColor: Colors.purple, // 设置选中颜色
            title: Text('Check me!'),
          ),
        ),
      ),
    );
  }
}
