Can you make an App overlay with Flutter on Android/iOS?

Issue

I am curious if it is possible to make an overlay with flutter which shows above the current app (android / iOS). I imagine it like the google translate app (as I do not have enough reputation I can only post a link to an image):

A flutter plugin to show Truecaller like overlay window, over all other apps along with callback events.
