set

fun set(factory: DispatchLifecycleScopeFactory)

fun set(factory: () -> CoroutineContext)

Override the default MainImmediateCoroutineScope factory, for testing or to include a custom CoroutineContext in production code. This may be done in Application.onCreate

If a DispatcherProvider element isn't present, DefaultDispatcherProvider.get will be added.
If a Job element isn't present, a SupervisorJob will be added.
If the ContinuationInterceptor does not match the one referenced by the possibly new property, it will be updated to match.
