Flow question:  What is recommended way to get a flow of tap events.  In android we give views a callback for these events.  This is where many devs will try to get started with flows, yet is unclear how to do so.  Is best way to use flowViaChannel with a callback that does channel.offer()?  Any thoughts on this?

Generally yes, that is how you bridge callback code to Flow code. Although note that `flowViaChannel` has been deprecated in favor of `channelFlow`.

Although if the listener you’re registering is a `setFoo` instead of `addFoo`, you might need to multicast. You could use a `BroadcastChannel` or David Karnok’s new library: <https://github.com/akarnokd/kotlin-flow-extensions>
