a gifimage for flutter,for solving gif cannot be controlled speed,progress
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"));
