中文文档

This library is an independent branch from flutter_vap, and the original library is no longer maintained.

Changes include: adding support for fusion animation, upgrading the flutter version, and merging existing PRs.

Backdrop #

Transparent video animation is currently one of the more popular implementations of animation. Major manufacturers have also open sourced their own frameworks. In the end, we chose Tencent vap, which supports Android, IOS, and Web, and provides natural convenience for us to encapsulate flutter_vap. Provides a tool to generate a video with an alpha channel from a frame picture, which is simply awesome.

VAP（Video Animation Player）is developed by Penguin E-sports and is used to play cool animations.

• Compared with Webp and Apng animation solutions, it has the advantages of high compression rate (smaller material) and hardware decoding (faster decoding)
• Compared with Lottie, it can achieve more complex animation effects (such as particle effects)

Preview #

And VAP can also merge custom attributes (such as user name, avatar) into the animation.

How to use #

import 'package:flutter_vap_plus/flutter_vap_plus.dart';

late VapController vapController;

IgnorePointer(
  // VapView can set the width and height through the outer package Container() to limit the width and height of the pop-up video
  child: VapView(
    fit: VapScaleFit.FIT_XY,
    onEvent: (event, args) {
      debugPrint('VapView event:${event}');
    },
    onControllerCreated: (controller) {
      vapController = controller;
    },
  ),
),

1. Play local video

  import 'package:flutter_vap_plus/flutter_vap_plus.dart';

  
  Future<void> _playFile(String path) async {
    if (path == null) {
      return null;
    }
    await vapController.playPath(path);
  }

2. Play asset video

  Future<void> _playAsset(String asset) async {
    if (asset == null) {
      return null;
    }
    await vapController.playAsset(asset);
  }

3. Set fusion animation during playback

import 'package:flutter_vap_plus/flutter_vap_plus.dart';

Future<void> _playFile(String path) async {
  if (path == null) {
    return null;
  }
  await vapController.playPath(path, fetchResources: [
    FetchResourceModel(tag: 'tag', resource: '1.png'),
    FetchResourceModel(
        tag: 'text', resource: 'test user 1'),
  ]);
}

4. Stop play

  VapController.stop()

5. Queue play

  _queuePlay()async{
    await vapController?.playPath(downloadPathList[0]);
    await vapController?.playPath(downloadPathList[1]);
    await _playAsset("static/demo.mp4");
  }
