Question re observing flagPole in SwiftUI in v3

[ryanbooker]

This is really just a question:

Am I right in thinking you can't just use the flagPole as if it were an observable, but rather have to observe the stream/publisher and then set some observable state to trigger view updates?

e.g. Text(flagPole.foo) is not dynamic it is just static data from when the screen reloaded. To update when it changes you need to onReceive(flagPole.$foo) or flagPole.$foo.sink or for await foo in flagPole.$foo and set an @State or whatever observable object you have?
