how to lock device for fixed time with kotlin or flutter
hey I wanna develop app that lock the device for a while
it's like this app bellow
https://play.google.com/store/apps/details?id=forinnovation.phoneaddiction&hl=EN
I can lock screen one time, but users can unlock easily
app needs to be foreground always
does anyone know how to realize that??
It's just for android (if available for iphone, please let me know)
