Is non blocking overlay possible with the plugin?

[tanzil114]

I have tried to implement an overlay that doesn't cover the whole screen but failed to do so. For example, I want to show a small UI card on home screen. User should be able to see and interact with the home screen of device normally. Currently, the overlay covers all screen, and we are not able to see any portion of, or interact with the home screen.

Can you please let me know how we can achieve it with this plugin?

I would also like to make a small widget as an overlay which has transparency so you can still see what is under it and does not receive touch events. I have the impression it is currently not possible due to flutter engine limitation, interesting info : flutter/flutter#9627
