flutter_gif

为了在 Flutter 中实现 Gif，我们可以使用 Image，但我们无法操作 Gif，例如：改变它的速度，控制它是否在某一帧播放，以及在哪个帧范围内循环。这个 widget 可以解决这些问题，它还可以帮助你包含 gif 缓存，避免每次加载帧。

用法（简单）

在 pubspec 中添加

     flutter_gif: ^1.0.0

简单用法

    FlutterGifController controller= FlutterGifController(vsync: this);


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

列出 FlutterGifController 中最常用的操作

// loop from 0 frame to 29 frame
controller.repeat(min:0, max:29, period:const Duration(millseconds:300));

// jumpTo thrid frame(index from 0)
controller.value = 0;

// from current frame to 26 frame
controller.animateTo(26);

如果你需要预缓存 gif，请尝试这个

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