What actually cancels a Flow? The act of stopping to collect it?

[Marc Knaup]

afaik a Flow ends if either
• the Flow is complete (no more elements, or exception thrown - e.g. when canceled).
• the Flow collector has thrown an exception - e.g. when cancelled.

takeWhile and alike throw a CancellationException internally

thank you

[Florian]

so when I collect in a coroutine scope and that scope is cancelled, the Flow is definitely cancelled

[Marc Knaup]

Yes, same with launchIn(scope)

[Florian]

thank you
