flutter 实现帧动画
This project is a starting point for a Flutter application.
💻 添加依赖 在 pubspec.yaml中添加:
frame_animate_widget: ^1.0.0
然后使用即可.
FrameAnimationImage();
//list 图片帧集合,
//interval 切帧时间,
FrameAnimationImage(list, width: 220, height: 200, interval: 50)
//由GlobalKey跨widget改变状态
final GlobalKey<FrameAnimationImageState> _key = new GlobalKey<FrameAnimationImageState>();
//start: false 此时要告诉widget 开始不播放动画
FrameAnimationImage(_key, list,
width: 220, height: 200, interval: 50, start: false)
//控制 widget 开始/继续;结束;重新开始 播放帧
_key.currentState.startAnimation();
_key.currentState.stopAnimation();
_key.currentState.reStartAnimation();
