React Hooks & useContext: Is This a Good Pattern?

Question

I'm studying useContext with React Hooks. I would like to pass a single object containing application state to context Consumers, e.g.:

<AppContextProvider.Provider value={AppState}>
  {props.children}
</AppContextProvider.Provider>

Of course, I will need to pass some getters and setters to enable child components to update application state.

Is this pattern an efficient approach -- is there a better pattern?

const AppContext = React.createContext();

function AppContextProvider(props) {
    const AppState = {
        aVideoCallIsLive: [get, set] = useState(false),
        channelName: [get, set] = useState(null),
        localVideoStream: [get, set] = useState(null),
        selectedBottomNavIndex: [get, set] = useState(-1),
        loginDialogIsOpen: [get, set] = useState(false),
    }
}

Why not use a reducer and pass a single dispatch function?

I believe its also recommended you pass state and dispatch is separate contexts otherwise calling dispatch will cause everything inside the context to re render.
