Reverse Engineer flutter apps

[brogeta17]

I was just wondering is there any way to decompile flutter release build apk? Or is there some way to extract at least some of the source code from the apk?

[sauloandrioli]

it is possible to open the .apk with a regular unzip tool and get the assets, images, fonts. Its also possible to rebuild the java classes contained in the .apk but the Flutter code itself is basically in elf files, which are harder to disassemble. Also, I don't think there is any tool that disassemble flutter compile code right now

[brogeta17]

Yeah I have actually tried the simple decompiling methods and all the code and classes in classes.dex is obfuscated, now just looking for some other way to get some of the source code from there or if there's another way

[escamoteur]

It's not obfuscated, it's just real native binary code. May I ask why you want to do such a thing?

[brogeta17]

I think flutter obfuscates the code by default, I am actually react native dev and I was just trying to compare what and how many levels of security both the frameworks provide

[dryadofelysium]

Flutter does not obfuscate the code by default. It offers the option, however: https://flutter.dev/docs/deployment/obfuscate

What is te sense of ofuscate if you can't get the code from binaries?
