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.
add in pubspec
GifController controller= GifController(vsync: this); GifImage( controller: controller, image: AssetImage("images/animate.gif"), )
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"));
