How can i achieve something like this for a functional component in Kotlin react. Below is a code snippet from a class component written in Javascript.
If you notice the code below updates the state and after something like a callback runs after. Basically what i want to achieve is to "Do something after state is updated" in a functional component.

this.setState(state => ({
      ...state,
      stack: [...state.stack, state.sceneConfig[sceneName]],
    }), () => {
      // Do something here
    });

var stack by useState(42)
useEffect(stack) {
    // Do something here
}
