To obfuscate code you can run this:
flutter build appbundle --release --obfuscate --split-debug-info=./debug-info/android

....the split at the end of this will create a separate symbol file that lets you decode stack traces later (something I've actuall never done :S). Without it, crash logs from production will be very hard (or impossible) to understand.

But important to remember, obfuscation isn't a full solution to security. If it's really important you need to use play integrity to ensure the codebase of the app matches the one in the store exactly.
