sdk: '>=2.15.0-116.0.dev <3.0.0'
When I run
flutter build appbundle/apk
Building without sound null safety
For more information see https://dart.dev/null-safety/unsound-null-safety
Running Gradle task 'bundleRelease'... 8.8s
Note: I have not opted out of null safety by using any of the workarounds. My entire project is 100% sound null safe. I’m also not looking for ways on how to build apk with sound null safety. The question is why is it printing
Building without sound null safety when everything is setup correctly.
What I’ve tried:
flutter pub get
Restarted the editor, etc.
dart pub outdated --mode=null-safety
Showing dependencies that are currently not opted in to null-safety.
[✗] indicates versions without null safety support.
[✓] indicates versions opting in to null safety.
Package Name Current Upgradable Resolvable Latest
direct dependencies: all support null safety.
dev_dependencies: all support null safety.
All dependencies opt in to null-safety.
Apologize. It was my blunder.
One of my files was opted-out of null safety as I was using
Once I removed it, the build started working again with null safety.
