Hello guys, are there any library to perform file tasks (create/read/write/delete) in Android/iOS???

take a look at https://github.com/square/okio

I tried using okio multiplatform alpha around february but didn't succeed. There wasn't much docs back then, though. Went the expect/actual way eventually

I had a similar experience, I finally used Korio https://korlibs.soywiz.com/korio/

Thank you guys. I will evaluate these options.

Can you code yourself by using expert, actual function
