Why `Flow<T>.collectWhile(predicate)` is in...

# coroutines

[Animesh Sahu]

Why Flow<T>.collectWhile(predicate) is internal in kotlinx.coroutines.flow ?
It could be useful to suspend a coroutine till value matches some predicate. Is Flow<T>.first(predicate): T considered to be used (as it utilizes the collectWhile) or something else to be used?

collectWhile is equivalent to transformWhile & emit + collect. Now that's not what you need as Roman just commented

How is this different than filter? Your collector is suspended while it doesn't receive new values

I use first to suspend until predicate. Looks really nice in code. Like flow.first { it > 0 }

Ah, thanks! Very much surprised Roman sir replied 😄😃🙂
