flutter gifimage

flutter_gifimage #
We should know that in order to achieve Gif in flutter, we can use Image, but we have no way to manipulate Gif, for example: change its speed, control it has been playing in a frame,
in which frame range loop. These problems can be solved by this widget,it also help you contain gif cache,avoid load frame every time.

list the most common operate in GifController:
// loop from 0 frame to 29 frame
controller.repeat(min:0,max:29,period:Duration(millseconds:300));

// jumpTo thrid frame(index from 0)
controller.value = 0;

// from current frame to 26 frame
controller.animateTo(26);

If you need to preCache gif,try this
// put imageProvider
fetchGif(AssetImage("images/animate.gif"));
