load method
- CacheImageProvider key,
- DecoderCallback decode
override
Converts a key into an ImageStreamCompleter, and begins fetching the image.
This method is deprecated. Implement loadBuffer for faster image loading. Only one of load and loadBuffer must be implemented, and loadBuffer is preferred.
The decode
callback provides the logic to obtain the codec for the
image.
See also:
- ResizeImage, for modifying the key to account for cache dimensions.
Implementation
@override
ImageStreamCompleter load(CacheImageProvider key, DecoderCallback decode) {
return MultiFrameImageStreamCompleter(
codec: _loadAsync(decode),
scale: 1,
debugLabel: tag,
informationCollector: () sync* {
yield ErrorDescription('Tag: $tag');
},
);
}
