How to add Compiler Argument in Android app?-CodePudding

I'm using Compose and some methods require the @OptIn(ExperimentalFoundationApi::class) annotation.
The thing is that the Android Studio keeps showing a warning in this annotation with the following message: This annotation should be used with the compiler argument '-opt-in=kotlin.RequiresOptIn'.
The code works normally but I would like to do what Android Studio suggests to remove this warning. How can I fix this?

CodePudding user response：

In the build.gradle from app module you can add the freeCompilerArgs = '-opt-in=kotlin.RequiresOptIn' inside kotlinOptions block. Like this:

plugins {
    // ...
}

android {
    // ...

    kotlinOptions {
        jvmTarget = '1.8'
        freeCompilerArgs  = '-opt-in=kotlin.RequiresOptIn'
    }

    // ...
}

dependencies {
    // ...
}
