In Readme of the animations package, I can see the fade scale transition working not only for a modal popup like AlertDialog but also for non-modal SnackBar, but could not find any detailed documentation on it. Files in example and test directories don't have related code either.
It looks like the fade scale transition provides only FadeScaleTransition and FadeScaleTransitionConfiguration; the former is for its (normal) child widget and the latter is for a modal dialog. SnackBar is neither of them, and I couldn't use it successfully although I tried in many ways.
Has anyone figured out how to use the package for SnackBar?
