نحو استفاده از mapdispathtoprops در Redux

با سلام.
بنده یک سورس مدیریت سبد خرید دارم که در زیرآمده است.اما نمی تونم در تابع MapDispathToProps صدا بزنم.لطفا راهنمایی کنید .
باتشکر .
actionTypes.js

export const ADD_TO_CART = 'ADD_TO_CART';
export const REMOVE_FROM_CART = 'REMOVE_FROM_CART';
export const ADD_QUANTITY = 'ADD_QUANTITY';
export const SUB_QUANTITY = 'SUB_QUANTITY';
export const EMPTY_CART = 'EMPTY_CART';

action.js

export const addToCart = id => {
  return {
    type: ADD_TO_CART,
    id
  };
};
export const removeFromCart = id => {
  return {
    type: REMOVE_FROM_CART,
    id,
  };
};
export const subtractQuantity = id => {
  return {
    type: SUB_QUANTITY,
    id,
  };
};
export const addQuantity = id => {
  return {
    type: ADD_QUANTITY,
    id,
  };
};
export const emptyCart = () => {
  return {
    type: EMPTY_CART,
  };
};

reducer.js

const initialState = {
  products: [],
};
const ShoppinReducer = (state = initialState, action) => {
  switch (action.type) {
    case ADD_TO_CART:
      return {
        ...state,
        products: state.products.map(product =>
          product.id === action.id ? {...product, selected: true} : product,
        ),
      };
    case REMOVE_FROM_CART:
      return {
        ...state,
        products: state.products.map(product =>
          product.id === action.id
            ? {...product, selected: false, quantity: 1}
            : product,
        ),
      };
    case ADD_QUANTITY:
      return {
        ...state,
        products: state.products.map(product =>
          product.id === action.id
            ? {...product, quantity: product.quantity + 1}
            : product,
        ),
      };
    case SUB_QUANTITY:
      return {
        ...state,
        products: state.products.map(product =>
          product.id === action.id
            ? {
                ...product,
                quantity: product.quantity !== 1 ? product.quantity - 1 : 1,
              }
            : product,
        ),
      };
    case EMPTY_CART:
      return {
        ...state,
        products: state.products.map(product =>
          product.selected
            ? {...product, selected: false, quantity: 1}
            : product,
        ),
      };
    default:
      return state;
  }
};
export {ShoppinReducer};
