loadThumbnail method
Load a downscaled thumbnail (JPEG bytes) for the photo-library asset
identified by localIdentifier. Returns null when the asset cannot be
resolved or decoded. maxWidth/maxHeight are an upper bound in logical
pixels; aspect ratio is preserved. Default throws.
Implementation
Future<Uint8List?> loadThumbnail(
String localIdentifier, {
int maxWidth = 256,
int maxHeight = 256,
}) =>
throw UnimplementedError(
'loadThumbnail is not implemented by this platform');
