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
flutter_gifimage: ^1.0.0
simple usage
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"));
