I Would Like To Get The Release Build Working Again Without Deleting Anymore Packages
Tried Multiple Stackoverflow Solutions And Google And Other Scources No Luck
Edit #1
When Setting The ext.kotlin_version = ‘1.6.10’ Got This
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:lintVitalRelease'.
> Could not delete old buildappreportslint-results-release-fatal.html
Trying A Secound Time Showed This Error `

Please try to change your
Kotlin Version
hope its help to you. and rebuild againflutter build apk --release
command, I just test on my machineform
to
after succeful build result
Try doing
flutter build apk
only. It generates app-release.apk also.Location:
build/app/outputs/flutter-apk/app-release.apk
I’m also using flutter v3.3.10. Works for me.
Edit:
I use
ext.kotlin_version 1.7.20
as mentioned below. Maybe you need to update your build.gradle to a newer version. Also replacejcenter()
withmavenCentral()
as JCenter Maven repository is no longer receiving updates.Also do
flutter clean
and invalidate and clear caches of your IDE, before building release apk.
