Flutter build signed apk or appbundle with code obfuscation

Question

I was looking for a way to obfuscate my Android APK/AppBundle, then I found this command :

flutter build apk --obfuscate --split-debug-info=/<project-name>/<directory>

But it doesn't have keystore information so I can't publish this file on the Google Play Console. Then, I found this post for building the app with keys but then it doesn't use obfuscation.

So, how do I build a release version of my app with Dart code obfuscation?

Answer 1

Obfuscate Code: We have 2 level for obfuscate your code:

• Obfuscate for native code (Java, Kotlin), this config will at gradle file. you can read more at:

https://developer.android.com/studio/build/shrink-code

• Obfuscate Dart code. (the same with your command)

https://docs.flutter.dev/deployment/obfuscate

You can obfuscate both Native Code and Dart Code.

Build release for APK.

• If you don't have keystore to sign app, you can create it with this guide:
