What Is Inside The .so File Generated By Flutter Android?

I have read @mraleph 's article, but still cannot understand what is inside the .so file generated by Flutter android. I have made an experiment: For my own app, I extract the .so

Solution 1:

its using c / c++ codes , .so files are c/c++ lib output files , generally flutter is using gnu gcc compiler , you can read jonathan levin android internals book (chapter 3) then you can get main concept
