Hi I am trying to add OptIn in my compiler gradle.

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    kotlinOptions {
        freeCompilerArgs += [
            "-Xuse-experimental=com.google.accompanist.permissions.ExperimentalPermissionsApi"
        ]
    }
}

I tried this piece of code but it giving me error. Can anyone guide me what I am doing wrong here

you still need to apply the OptIn annotation to the class or function thats invoking the experimental API

[KotlinLeaner]

okk

[KotlinLeaner]

So no other way to remove in every class OptIn?

I remember getting this to work as described, but it's been too long ago that I could tell you what's wrong here. But as I said, iirc, it's worth it to keep looking.

[Ciaran Sloan]

i think maybe your syntax is a little wrong. Try this:

"-opt-in=com.google.accompanist.permissions.ExperimentalPermissionsApi"

Perfect It works.. @Ciaran Sloan Thanks
