Flutter动画效果插件magic_animate的使用

Flutter动画效果插件magic_animate的使用

Magic Animate

精美的动画效果灵感来源于magic.css，每个动画都以可定制的小部件形式呈现。

特性

使用Flutter完全实现了Magic.css动画库的交互效果。

开始使用

首先，你需要在pubspec.yaml文件中添加magic_animate依赖：

dependencies:
  magic_animate: ^x.x.x

然后，在你的Dart文件中导入magic_animate包：

import 'package:magic_animate/magic_animate.dart';

支持的动画

Magic Animate支持多种动画效果，包括但不限于以下几种：

• MBoingWidget
• MBombWidget
• MFoolishWidget
• MHole_outWidget
• MMagicWidget
• MOpenWidget
• MPerspectiveWidget
• MPuffWidget
• MRotateWidget
• MSlideWidget
• MSpaceWidget
• MSwapWidget
• MSwashWidget
• MTinWidget
• MTwisterInWidget
• MVanishWidget

使用方法

每个动画小部件都有一个onController函数，该函数返回一个AnimationController，允许你通过AnimationController来控制动画的状态。以下是一个使用示例：

class MXXXWidget extends StatefulWidget {
  final Widget child;
  final Duration duration;
  final MagicControllerFn onController;
  final MXXXType type;
  const MXXXWidget({
    super.key,
    required this.child,
    required this.onController,
    required this.type,
    this.duration = const Duration(milliseconds: 1000),
  });

  [@override](/user/override)
  State<MXXXWidget> createState() => _MXXXWidgetState();
}

class _MXXXWidgetState extends State<MXXXWidget> {
  late AnimationController _controller;

  [@override](/user/override)
  void initState() {
    super.initState();
    _controller = AnimationController(vsync: this, duration: widget.duration);
    widget.onController(_controller);
  }

  [@override](/user/override)
  void dispose() {
    _controller.dispose();
    super.dispose();
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return widget.child;
  }
}

完整示例

下面是一个完整的示例代码，展示了如何使用Magic Animate插件创建一个具有多种动画效果的页面。

import 'package:example/conts.dart';
import 'package:example/magic_item.dart';
import 'package:example/magic_wrap.dart';
import 'package:flutter/material.dart';

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

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

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Magic Animate',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: const Color(0xFFFD287F)),
        useMaterial3: true,
      ),
      home: const MyHomePage(),
    );
  }
}

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

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String _selAnimation = '';

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: const Color(0xFF17171E),
      body: Column(
        children: [
          Container(
            height: 200,
            width: double.infinity,
            alignment: Alignment.center,
            child: Stack(
              alignment: Alignment.center,
              children: [
                Container(
                  height: 100,

                  decoration: BoxDecoration(
                    color: const Color(0xFF3A3947),
                    borderRadius: BorderRadius.circular(10),
                  ),
                ),
                Positioned(
                  child: MagicWrap(
                    type: _selAnimation,
                    child: Container(
                      height: 100,
                      width: 100,
                      decoration: BoxDecoration(
                        color: const Color(0xFFFD287F),
                        borderRadius: BorderRadius.circular(10),
                      ),
                      child: const Icon(Icons.flutter_dash, size: 50, color: Colors.white),
                    ),
                  ),
                ),
              ],
            ),
          ),
          Expanded(
            child: SingleChildScrollView(
              child: Padding(
                padding: const EdgeInsets.only(bottom: 100),
                child: Column(
                  mainAxisSize: MainAxisSize.min,
                  children: magicList
                      .map((e) => MagicItem(
                            group: e,
                            onChange: (value) {
                              setState(() {
                                _selAnimation = value;
                              });
                            },
                          ))
                      .toList(),
                ),
              ),
            ),
          ),
        ],
      ),
