FlowHelper.kt

inline fun <T> Flow<T>.catchLog(default: T? = null): Flow<T> = this.catch { e ->
    if (e is CancellationException) throw e 
    Timber.e(
        e,
        "Error from flow (${coroutineContext[CoroutineName]?.name}): " +
            "${e.stackTraceToString()}"
    )
    default?.let { emit(it) }
}

// call-site
runBlocking {
    flow {
        emit(1)
        throw RuntimeException("unexpected")
        emit(2)
    }
        .catchLog(default = 0)
        .collect { println(it) }
}


// result:
1
Error from flow (name): [stacktrace]
0 // default in case of error
