Hello there!

Is there a way to check if a Flow<T> with debounce(...) operator applied to it has currently a pending value that will be emitted after debounce delay?

I have a specific problem with the following use case on Android. Inside a ViewModel, I am using a Channel<String> to organize pipeline for sending text changes to some remote backend: this channel is consumed as Flow<String>, where on each emission the value is sent (with delay resulting from debounce() operator) to the backend. When this ViewModel is to be destroyed and onCleared() is called, I cancel that same Channel<String>. But there is an expected but still unpleasant side-effect, which I need to eliminate: the last value is not guaranteed to be sent if there is a pending emission due to debounce delay, which gets cancelled when channel.cancel() is called.

Any suggestions will be very appreciated!

If you switch to channel.close() all events will be processed (assuming collector is working in non-cancelled scope)
