Let’s Dive in! 🤿

Coroutine Scope

You need a Coroutine Scope to launch a Coroutine. This basically ties a Coroutine to the lifecycle from where it is launched. When the lifecycle is killed, all the Coroutines in that Scope will be terminated hence helping in handling memory leaks.

You’ll mostly need to use lifecycleScope, _for when you launch a coroutine from an Activity/Fragment or _ViewModalScope , _fromwhen you launch from a viewModel and _GlobalScope, for a coroutines that are operating in the application lifetime.

Coroutine Builders

You can start a coroutine by

• _launch{} — _Start a coroutine and forget about it.
• _async, await — _This returns a differed object and then we call await to wait for the result.
• runBlocking — blocks current thread until coroutines executes
