Updated The Pubspec Files

I updated the pubspec files and the android builder to support Android version 31.

If we update the gradle version from 3.5.0 to 4.1.0 in the android example

「Direct local .aar file dependencies are not supported when building an AAR」 error occurs...

We need to update the gradle since it will be incompatible with other plugins... any idea to make it works even with gradle 4.1.0?

I have been trying to figure out the same thing. I have a fork that I am playing with to try and get it to work.
