function counter(state = 0, action) {
  switch (action.type) {
    case 'INCREMENT':
      return state + 1;
    case 'DECREMENT':
      return state - 1;
    default:
      return state;
  }
}

// Create a Redux store
const store = createStore(counter);

3. Wrap your root component with the Provider component from react-redux:

import { Provider } from 'react-redux';

function App() {
  return (
    <Provider store={store}>
      {/* Your app components */}
    </Provider>
  );
}

4. Connect your components to the Redux store using the connect function from react-redux:

import { connect } from 'react-redux';

function Counter({ value, increment, decrement }) {
  return (
    <View>
      <Text>{value}</Text>
      <Button title="Increment" onPress={increment} />
      <Button title="Decrement" onPress={decrement} />
    </View>
  );
}

const mapStateToProps = (state) => ({
  value: state,
});

const mapDispatchToProps = (dispatch) => ({
  increment: () => dispatch({ type: 'INCREMENT' }),
  decrement: () => dispatch({ type: 'DECREMENT' }),
});

export default connect(mapStateToProps, mapDispatchToProps)(Counter);
