What's next after manually building ffmpeg-kit for Android?

[Somtobro]

Gooday guys, I'm primarily a flutter developer so I'm not vast with natively building android apps.
Anyways, I just recently built x264 to work for Android yh by running
./android.sh --enable-x264 --enable-gpl
Ps:I'm not even actually sure if this is the whole command because I'm trying to build for all arms.
Anyways, after running that line of code above It was successful
x264: already built
cpu-features:already built
So I assume that's good

So I checked the prebuilt folder in ffmpeg-kit folder and I was confused.
First of all I saw only one folder I expected to see different for all the files.
Also and most importantly I was expecting .aar or .so files.
I've checked the wikis , I didn't see any doc for what to do after building and also on how to integrate it in the flutter app or react native.Maybe I'm the one that missed it it could be possible.
Any help will be highly highly appreciated please.
Thank you
And I wanted to say God bless the guys that built this package and documented it.
I spent weeks trying to build this stuff directly using ffmpeg 6, I was highly frustrated then later gave up until I saw this package and decided to give it another show
It worked on my like 3rd trail on the same day.
That's wonderful.
God bless you again
