combine
fun <T1 : Any, T2 : Any, T3 : Any, T4 : Any, T5 : Any, T6 : Any, T7 : Any, T8 : Any, R> combine(flow: Flow<T1>, flow2: Flow<T2>, flow3: Flow<T3>, flow4: Flow<T4>, flow5: Flow<T5>, flow6: Flow<T6>, flow7: Flow<T7>, flow8: Flow<T8>, transform: suspend (T1, T2, T3, T4, T5, T6, T7, T8) -> R): Flow<R>
Returns a Flow whose values are generated by transform function that process the most recently emitted values by each flow.
The receiver of the transform is FlowCollector and thus transform is a generic function that may transform emitted element, skip it or emit it multiple times.
