How to cancel/unsubscribe from coroutines Flow

I want to add that in 1.3.7 version emissions from flow builder now check cancellation status and are properly cancellable. So the code in question will work as expected

I came across a workaround in this related issue

I have replaced every single collect with a safeCollect function in my project:

/**
 * Only proceed with the given action if the coroutine has not been cancelled.
 * Necessary because Flow.collect receives items even after coroutine was cancelled
 * https://github.com/Kotlin/kotlinx.coroutines/issues/1265
 */
suspend inline fun <T> Flow<T>.safeCollect(crossinline action: suspend (T) -> Unit) {
  collect {
    coroutineContext.ensureActive()
    action(it)
  }
}
