FadeInImagePlaceholder class

An image that shows a placeholder widget while the target image is loading, then fades in the new image when it loads.

This is similar to FadeInImage but the difference is that it allows you to specify a widget as a placeholder, instead of just an ImageProvider. It also lets you override the child argument, in case you want to wrap the image with another widget, for example an Ink.image.
