Let's assume we have an app that has some settings and one of the settings is a switch button which changes the color (or font size, whatever) of the `Text` . The setting is stored in `DataStore`.

Only in certain screens and at specific places the `Text` must change based on the settings.
So imagine we wrap this `Text` in a composable named `DynamicText` .
The `DynamicText` can be found in ScreenA, ScreenB and ScreenD.

One way I assume to achieve this is to observe the setting in the viewmodels of those screens and update `DynamicText`.

However is there any other way to achieve this? I imagine something like a singleton class "Observer" that holds the value of the setting and we can somehow pass it to `DynamicText` , is that possible?
Or any other way?

If you want this part of the screens to not come from the ViewModels you could take some inspiration from <https://github.com/android/nowinandroid/blob/43d6614cb886bbdd5bf9915f22aa92dd9670cdfb/app/src/main/kotlin/com/google/samples/apps/nowinandroid/ui/NiaAppState.kt#L129-L141|NiA for example> where some part of the App state is just held in a normal state object, which is constructed in your <https://github.com/android/nowinandroid/blob/43d6614cb886bbdd5bf9915f22aa92dd9670cdfb/app/src/main/kotlin/com/google/samples/apps/nowinandroid/MainActivity.kt#L136-L141|main activity> for example, and you can pass this down to any composable which is interested in this state.
The source of truth can still be a DataStore or whatever you want it to be.

hmm that seems quite what I wanted.
