the compose repo of github almost is ui widget，and we need more cross platform lib like permission request on all platform

As it matures there will be more off the shelf ready to use libraries. In the meantime you can either expect/actual on each platform or depend on abstraction in common code and inject implementations from each platform. That's what most of the libraries do, nobody wants to reimplement the wheel unless is critical reimplementing the wheel in pure kotlin side

yep ，looking forward

we support this in our kaluga library: https://github.com/splendo/kaluga/tree/develop/base-permissions

It is great work, my feedback: it would be better to split all those utilities in smaller libraries. I wouldn't have to bring the full library just for something little I might need, like only Bluetooth, for example

they are split already, they just share some base code. if you want only bluetooth permissions you just do

implementation("com.splendo.kaluga:bluetooth-permissions:$kalugaVersion")

I just realized right, sorry I didn't check the readme or the gradle files.

that’s ok. the example app has a demonstration of permissions usage, e.g. the shared code in https://github.com/splendo/kaluga/tree/develop/example/shared/src/commonMain/kotlin/com/splendo/kaluga/example/shared/viewmodel/permissions
