extract flutter source code from release apk

Question

Actually I have lost my source code to my app and what I am left with is release apk. I come across some answers of extracting source code from debug apk. But I am afraid that I don't have debug apk.

So is there any way to get source code or have I lost it totally?

Thanks in advance for answer.

Answer 1

It's hard, but not impossible to extract source code from a Release apk, mostly reverse engineering.

There are some projects / blogs talking about this:

If you're looking for only a part of the code, try binary instrumentation (Frida)

Answer 2

You can't export the source code from apk
