Constructors
- ImagePainter({Key? key, required Uint8List imageBytes, required Widget placeholder, Image? precachedImage, void onImageLoaded(Image)?})
-
Create an ImagePainter that loads an image from a byte array.
The
onImageLoaded
callback is called when the image is loaded. Theplaceholder
widget is displayed while the image is loading. Optionally aprecachedImage
can be provided to display the image directly without altering the calling widget between caching.const
