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.

  • TODO: Describe initial release.

Health issues and suggestions

Document public APIs (-9.09 points)

20 out of 22 API elements (library, class, field or method) have no adequate dartdoc content. Good documentation improves code readability and discoverability through search.

Maintenance suggestions

The description is too short. (-20 points)

Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

Package is pre-v0.1 release. (-10 points)

While there is nothing inherently wrong with versions of 0.0.*, it usually means that the author is still experimenting with the general direction of the API.
