+# 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"));
+
+ ```
