Requires Flutter 1.6.7 or higher.
A widget for Flutter that displays a placeholder widget while a specified image loads, then cross-fades to the loaded image. Also handles progress and errors.
If image is changed, it will cross-fade to the new image once it is finished loading. Setting image to null will cross-fade back to the placeholder.
You can set fadeDuration and fadeCurve, as well as most Image properties:
width, height, fit, alignment, repeat, matchTextDirection, excludeFromSemantics and semanticLabel.
You can also specify a loadingBuilder that will display load progress any time a new image is loaded, and an errorBuilder that will display if an error occurs while loading an image.
See the example directory for a simple example.
