My App Bundle Download Size in Google PlayStore is around 23 MB:
But Why after installed, the App Size on Disk raises significantly to 83 MB:
Any Idea why this happens, because:
1) Flutter's assets file (images, sound & fonts) on projects only around 11 MB
2) Size of Flutter Source Code (.dart) on disk only 1.4 MB
3) Android Native Resource/icon (Res) only around 800 KB

Any Idea How to reduce App On Size?
Thank You in Advance...
UPDATE
If I set minifyEnabled = true and shrinkResources = true (as suggested by Ravinder Kumar) in my build.gradle then it will generate a very long error, here's the log:

... ( I cut the error log because of very long, but full log can bee seen here: https://www.dropbox.com/s/jy92d1lmj9pgb6d/full_flutter_error_log.txt?dl=0 )
