unable to recover my files from imported flutter project

gistfile1.txt

hi there!
i backed up my flutter project folder due to some issues with my drive,
i fixed the issues
only for me to try importing the project and continuing my work
and it turns out i cant find my main.dart file along with my entire lib folder
the only recognizable thing left in the project seems to be the assets folder

help me please
this has really pushed me wayy behind schedule 

also i would be much greatful if i could get an app that decompiles flutter apks
as my code is still in debug mode and i have the apk file.

thanks
