## AI overview

This tutorial explains Kotlin Coroutines Flow by deriving its implementation from a suspending lambda, then introducing a functional interface, receiver, object expression, builder function, and generic type parameter. It concludes that the basic builder closely models how flow, emit, and collect are implemented.
