Kuidas jälgida oleku muutusi Jetpack Compose'is?

In Jetpack Compose, state changes are monitored using special data types and mechanisms that automatically trigger UI redraws when the state changes.

Main methods:

• MutableState<T> — a wrapper around a value that notifies Compose of changes.
• Using the remember function to store state within the composition.
• Using State and LiveData from ViewModel, which Compose can observe.

Example:

@Composable
fun Counter() {
    var count by remember { mutableStateOf(0) }

    Button(onClick = { count++ }) {
        Text("Pressed $count times")
    }
}

Here, mutableStateOf creates an observable state. When count changes, Compose automatically redraws the button with the new value.
