Easy coroutine cancelation

In this recipe, we are going to explore how to implement a coroutine that allows us to cancel its execution. We are going to create an infinite progress-bar animation running in the console in the background using a coroutine. Next, after a given delay, we are going to cancel the coroutine and test how the animation behaves.

Getting ready

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.23.3' 

The preceding code declares the kotlinx-coroutines-core dependency in a Gradle build script, which is used in the sample project (https://github.com/PacktPublishing/Kotlin-Standard...
