Android:Evo-gen [Trj]: Our App detected as Malicious Apps

Hi!
I am from PropNex Indonesia.
Currently, we develop an Android and iOS app using Flutter named “PropNex Plus”, you can find it at https://play.google.com/store/apps/details?id=id.propnexplus.com and https://apps.apple.com/id/app/propnex-plus/id1550246845

We have been developing this app since March 2021.
Recently, we update our app in Play Store and App Store. After that, some of our users reported us that our app detected as Malicious Apps. We tried to analyze this app using virustotal.com and detected as “Android:Evo-gen [Trj]” in Avast-mobile. ​It is false positive. We didn’t do anything with our apps. We just add a library called “awesome_notifications” from pub.dev for managing our notification service.

It might be a caused but I guess, Possibly there is an issue with Avast heuristic detection. Please resolve it as soon as possible.
Thanks.
