channel.offer is now deprecated. Can anybody please help me understanding the trySend? I can see 3 flags like isSuccess, isFailure and isClosed. When should I use what?

suspend fun fetch(): Result<List<User>> {
    collectFlow {
        if (...)

offer(Result.Success(listOf(...)))
        else
        offer(Result.Error(Exception())
    }
}

How this can be converted into trySend? Shall I use, trySend(Result.Success...).isSuccess or trySend(Result.Error...).isSuccess.

When should I use trySend...isFailure and trySend...isCancel?

It depends on how you were using offer before. And it depends on how you want to send items to the channel.
• Just want to try and offer a value? Then just trySend
• Also want to know if sent? isSuccess is what you need.
• Want to handle a failure to send? Then use either of the other options.
If you are in a suspending context, you might want to send instead of trySend.
