# 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.

# Usage(Simple)
  add in pubspec

   ```dart

        flutter_gifimage: ^1.0.0

   ```

 simple usage

 ```dart
     GifController controller= GifController(vsync: this);


     GifImage(
          controller: controller,
          image: AssetImage("images/animate.gif"),
     )

 ```

 list the most common operate in GifController:


 ```dart
 // 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

 ```dart
 // put imageProvider
 fetchGif(AssetImage("images/animate.gif"));

 ```
