Integrating Flutter app into Unity

I’m using flutter_unity_widget module. This module is running unity app on the flutter. Problem is memory managning is not working same as in unity sole build, and android build is locked to 150mb.
I want my flutter app run on unity app, and communicate eachother.
If anyone provide information how to do it, I’ll really appriceate.

I suspect you will not get any response to such a specific question about a specific third party package here. Instead you should contact the developers directly through the github page of the project, either via posting an ‘issue’ or contacting the developer named in the ‘Notice’ section.
