How to add Google Play In-app Review Dialog?

A step-by-step guide how you can let users review your app using Google Play In-app review API and test it out using Internal App Sharing

This is just a quick guide and a simple example of how to add the Google Play In-app review dialog in your app. This is what it looks like after I implemented this in RSS feed reader app.

1. Add Review API Libraries

This example of build.gradle.kts ( Kotlin script/KTS) in your app module.

dependencies {
    /*...*/
    implementation("com.google.android.play:review:2.0.1")
    implementation("com.google.android.play:review-ktx:2.0.1")
    /*...*/
}

2. Create ReviewManager in the Activity

It is better to implement the ReviewManger in activity rather than a composable function because its APIs needs an activity. Well, you can technically do it in composable function (through LocalContext), but it is not a good practice because composable functions shouldn't need to know about the activity.
