I want to combine multiple flows by

combine

function in variable x as following:

val x = combine(flow1, flow2) { (flow1, flow2) ->
    listOf(flow1, flow2)
}

when I call collect on x flow the result will be empty because flow1 and flow2 not ready yet, so I want to trigger collect on each flow gets ready to get latest data always.

What do you mean by not ready yet?

flow1 and flow2 are data from API which take some time to get ready.

So? If it takes a while then the flow while suspend for a while.

flow1.onStart { emit(defaultValue) }

And the same for flow2

Isn't it normal that flows would take time to emit values? The consumer will wait then.
