Native Code Obfuscation about flutter HOT 5 OPEN

I also tried searching online for ways to obfuscate iOS/swift code but I saw the same libraries that you did which were either not maintained or required a license.

This however seems like a good feature to support if we can. I'm not entirely familiar with what obfuscation support is like for the other platforms flutter supports as well so I'll be labeling this as a proposal for further insight from the team.

Hi @falt008, do you use proguard & r8 for your android app? I think for android it should suffice. That is what the android docs recommend https://developer.android.com/build/shrink-code#obfuscate

Hi @danagbemava-nc, we currently do not have an Android Version of our App - only iOS. Does progruard solve this issue (including dependencies) for Android?

Hi @falt008, afaik, using proguard & r8 should resolve this for android. Although, a motivated attacker can still get sensitive data in your code if you don't employ additional security measures. Regarding iOS, do you know of any way (without third-party intervention) to obfuscate the code?

@danagbemava-nc As I have few experience with native iOS development I don't know any way to do this. I found some third party obfuscation tools but most of them seem to be deprectated or have to be licensed (SwiftShield, obfuscator-llvm, iXGuard). I guess you would also need a way to obfuscate Objective C Code if it is still used by some packages to do native implementation? I don't know how widely used is Objective C compared to Swift.
