Hi, Can anyone give me and example of using Channel with suspendCancellableCoroutine, for observing firebase document updates

[Manuel Vivo]

callbackFlow should be enough for your use case. TAL https://github.com/google/iosched/blob/main/shared/src/main/java/com/google/sample[…]ed/data/signin/datasources/FirestoreRegisteredUserDataSource.kt

How to avoid this error , java.lang.IllegalStateException: Already resumed, but proposed with update ?

[Manuel Vivo]

When does the error happen?

[Viral Thakker]

when resume is called twice on suspendCancellableCoroutine

[Viral Thakker]

Any workaround for that, I did not understand your example

[Manuel Vivo]

suspendCancellableCoroutine cannot emit multiple times, that’s why you need callbackFlow
