remember
Return an AsyncImagePainter that executes an ImageRequest asynchronously and renders the result.
Parameters
Either an ImageRequest or the ImageRequest.data value.
The ImageLoader that will be used to execute the request.
A Painter that is displayed while the image is loading.
A Painter that is displayed when the image request is unsuccessful.
A Painter that is displayed when the request's ImageRequest.data is null.
Called when the image request begins loading.
Called when the image request completes successfully.
Called when the image request completes unsuccessfully.
Used to determine the aspect ratio scaling to be used if the canvas bounds are a different size from the intrinsic size of the image loaded by model. This should be set to the same value that's passed to Image.
Sampling algorithm applied to a bitmap when it is scaled and drawn into the destination.

Parameters
Either an ImageRequest or the ImageRequest.data value.
The ImageLoader that will be used to execute the request.
A callback to transform a new State before it's applied to the AsyncImagePainter. Typically this is used to overwrite the state's Painter.
Called when the state of this painter changes.
