ThumbnailGeneratedCallback typedef
A callback function type that is invoked when a thumbnail image is generated.
This callback provides the generated thumbnail image bytes and the raw image
as its parameters. It is expected to return a Future<void>
, allowing for
asynchronous operations to be performed if needed.
The thumbnailBytes
parameter contains the bytes of the generated thumbnail image.
The rawImage
parameter contains the raw ui.Image
object of the original image.
Implementation
typedef ThumbnailGeneratedCallback = Future<void> Function(
Uint8List thumbnailBytes, ui.Image rawImage);
