如何在flutter中设计LikeButton的样式？

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

class LikeButtonExample extends StatefulWidget {
  @override
  _LikeButtonExampleState createState() => _LikeButtonExampleState();
}

class _LikeButtonExampleState extends State<LikeButtonExample> {
  bool _isLiked = false;

  @override
  Widget build(BuildContext context) {
    return LikeButton(
      isLiked: _isLiked,
      onTap: (bool isLiked) {
        setState(() {
          _isLiked = !_isLiked;
        });
        return Future.value(!_isLiked);
      },
    );
  }
}

LikeButtonExample(),
