gif_ani 0.0.2

gif_ani #

a flutter plugin to control gif animation

The example screen shot

Usage #

GifController is subclass of AnimationController. GifAnimation is just used like Image.

import 'package:gif_ani/gif_ani.dart';
GifController _animationCtrl = new GifController(vsync: this,duration: new Duration(milliseconds: 1200),frameNum: 32);
Widget ret = new GifAnimation(
    image: new AssetImage("like_anim.gif"),
    animationCtrl: _animationCtrl,
);

then you can control the gif animation by _animationCtrl:

///run the anim from start
_animationCtrl.runAni();

///set the Image with specified frame
_animationCtrl.setFrame(10);

///or you can use other action as a AnimationController
_animationCtrl.repeat();
_animationCtrl.reverse();
_animationCtrl.reset();

[0.0.1] - TODO: Add release date.
