Flutter卡片翻转与滑动插件 flip_card_swiper 的使用

简介

flip_card_swiper 是一个可定制的、支持平滑翻转动画和触觉反馈的卡片组件，适用于Flutter应用。它提供了丰富的功能，包括翻转和滑动动画、卡组动画、动态更新等。

特性

• 翻转与滑动动画：通过垂直拖动手势轻松在卡片之间切换。
• 卡组动画：自动将卡片动画化为集合，非常适合引导序列或展示。
• 触觉反馈：提供用户翻转卡片时的触觉反馈，增强用户体验。
• 动态卡片更新：在动画中途更新卡片顺序，实现无限循环浏览卡片集。
• 自定义缩放和偏移：微调卡片位置、缩放比例和过渡效果，以实现独特的翻转和堆叠效果。

安装

在你的 pubspec.yaml 文件中添加以下依赖：

dependencies:
  flip_card_swiper: ^1.0.0

然后运行：

flutter pub get

使用示例

下面是一个完整的示例代码，展示了如何使用 flip_card_swiper 插件来创建一个带有翻转和滑动功能的卡片组件。

示例代码

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

void main() => runApp(const MyApp());

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

  @override
  State<MyApp> createState() => _MyAppState();
}

  bool _shouldPlayAnimation = false;
  final List<Map<String, dynamic>> cards = [
    {'color': Colors.blue, 'text': 'Card 1'},
    {'color': Colors.red, 'text': 'Card 2'},
    {'color': Colors.green, 'text': 'Card 3'},
    {'color': Colors.purple, 'text': 'Card 4'},
    {'color': Colors.orange, 'text': 'Card 5'},
