[vector_graphics] Allow transition between placeholder and loaded image to have an animation #158857
Description
Imported from dnfield/vector_graphics#193
Original report by @jaggernod on Mar 9, 2023
Images fetched from the network can take significant time to load.
Unfortunately, when a placeholder is defined and the remote asset is loaded we see an immediate switch (pop-in).
Could we provide animation for the transition or have a crossfade (with user-defined duration) between the placeholder and the final image?
The original flutter_svg already had this question posted.
P.S. Thank you for the package. It is really useful

I'm open to this but doubt I will have time to work on it myself anytime soon.
