cached_gif

Description:

cached gif

gif #
Overview #
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.
Example #
Load a gif asynchronously and display a text placeholder during loading.
When the gif is loaded reset the controller and run the gif to the end.

final asset = AssetImage("images/animate.gif");


// add Future to store prepared Gif in memory
// and clear it from RAM after Timeout.
unawaited(
GifCacheManager().addGifToCache(
asset,
clearTimeout: const Duration(minutes: 4),
),
);

GifController _controller = GifController(vsync: this);

Gif(
image: asset,
controller: _controller, // if duration and fps is null,
// original gif fps will be used.
//fps: 30,
//duration: const Duration(seconds: 3),
autostart: Autostart.no,
placeholder: (context) => const Text('Loading...'),
onFetchCompleted: () {
_controller.reset();
_controller.forward();
},
),
