LiveDataScope

latestValue

@Nullable
public abstract @Nullable T latestValue

References the current value of the LiveData.

If the block never emited a value, latestValue will be null. You can use this value to check what was then latest value emited by your block before it got cancelled.

Note that if the block called emitSource, then latestValue will be last value dispatched by the sourceLiveData.

emit

@NonNull
public abstract void emit(@NonNull T value)

Set's the LiveData's value to the given value. If you've called emitSource previously, calling emit will remove that source.

Note that this function suspends until the value is set on the LiveData.

emitSource

@NonNull
public abstract DisposableHandle emitSource(@NonNull LiveData<@NonNull T> source)

Add the given LiveData as a source, similar to MediatorLiveData.addSource. Calling this method will remove any source that was yielded before via emitSource.
