Question

Confused I was going to start adding some ` Model`to my little demo learning playgrounds but the IDE doesn t recognize that annotation Nor does it offer an import Is this something that is either too new or perhaps old deprecated

Where did you see this ` Model` annotation

Filip Wiesner · Answer

That is really really old Compose concept if I remember correctly Got eventually replaced by `mutableStateOf ` but I never used it I just remember it from the first presentation at Google I O That didn t even get to Compose 1 0 older man

If you re a new to the territory guy and you don t need to transition from MVVM or whatever and do halfway implementations what is the story for bridging a domain model with one s app Googling for this kind of stuff turns up so many of those hella old hits that you can t tell the wheat from the chaff

Filip Wiesner · Answer

Just stick to official documentation imho When you get the basics you can start wildly googling sweat smile

Travis Griggs · Answer

I guess here s the bridge I m struggling with I ve read and reread an official doc <https developer android com jetpack compose state> I have in my mind a heirarchical object model that models my domain real world agricultural devices synced via BLE MQTT I don t get a clear picture when I read that official doc how I mg going to tweak my model objects so that recomposition happens when it ought to Do I just start putting anything that changes in a LiveData and go that route

Travis Griggs · Answer

Or is it as simple as just use mutableState in your domain model fields that would trigger changes

Stylianos Gakis · Answer

Your previous message feels like a bit too much for me to understand and answer confidently But for your last one you can either save stuff inside MutableState directly Or even a `StateFlow` where you then read it by converting it to state with collectAsState or collectAsStateWithLifecycle and yes it should just reflect those changes in your UI But again I think that what Filip is saying is your best bet Get familiar with the basic concepts first and then it will be quite a lot easier to figure out the rest
