Flutter security

There is a simple procedure for obfuscation of the flutter app, you only need to run the build command for the release version using the –obfuscate flag combined with the –split-debug-info flag . Once you’ve obfuscated your binary, save the symbols file. You need this if you later want to de-obfuscate a stack trace.

Flutter compiles your Dart to native assembly code and uses formats that have not been publicly documented in-depth let alone fully decompiled and recompiled .

Flutter Secure Storage provides API to store data in secure storage . Keychain is used in iOS, KeyStore based solution is used in Android.

Each user in the application has their own public-private key pair. Public keys are distributed publicly and encrypt the sender’s messages . The receiver can only decrypt the sender’s message with the matching private key, which is used to decrypt messages and to verify or sign them.
