Function useState 

pub fn useState<T: Clone + 'static>(init: impl FnOnce() -> T) -> MutableState<T>

A composable hook that creates and remembers a MutableState.

This is the primary way to define local state in a composable function. It combines remember and mutableStateOf.

Arguments

• init - A closure that provides the initial value. This is only called once when the composable enters the composition.

Example

#[composable]
fn Counter() {
    // "count" persists across recompositions.
    // If we used mutableStateOf directly, it would reset to 0 every frame.
    let count = useState(|| 0);

    Button(
        onClick = move || count.set(count.value() + 1),
        || Text(format!("Count: {}", count.value()))
    );
}
