Creating a complete codebase for a personalized meal planning and grocery delivery app is a large task. However, I can help you get started with a basic structure using a popular framework like React Native for cross-platform development. Below is a simplified example focusing on setting up a basic app with a home screen and navigation.

React Native App Structure

1. Set up the development environment:

   • Install Node.js, npm, and React Native CLI.
   • Set up Android Studio and Xcode for Android and iOS development, respectively.

2. Create a new React Native project:

   npx react-native init MealPlannerApp
   cd MealPlannerApp

3. Install necessary packages:

   npm install @react-navigation/native @react-navigation/stack
   npm install react-native-screens react-native-safe-area-context

4. Basic App Structure:

// App.js
import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import HomeScreen from './screens/HomeScreen';
import DetailsScreen from './screens/DetailsScreen';

const Stack = createStackNavigator();

const App = () => {
  return (
    <NavigationContainer>
      <Stack.Navigator initialRouteName="Home">
        <Stack.Screen name="Home" component={HomeScreen} />
        <Stack.Screen name="Details" component={DetailsScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  );
};

export default App;

5. Create Screens:

// screens/HomeScreen.js
import React from 'react';
import { View, Text, Button } from 'react-native';

const HomeScreen = ({ navigation }) => {
  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Text>Welcome to the Meal Planner App!</Text>
      <Button
        title="Go to Details"
        onPress={() => navigation.navigate('Details')}
      />
    </View>
  );
};

export default HomeScreen;

// screens/DetailsScreen.js
import React from 'react';
import { View, Text } from 'react-native';

const DetailsScreen = () => {
  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Text>Details Screen</Text>
    </View>
  );
};

export default DetailsScreen;

6. Running the App:
   • For iOS: npx react-native run-ios
   • For Android: npx react-native run-android

Next Steps

• Backend Integration: Use Firebase or another backend to manage user data and meal plans.
• State Management: Consider using Redux or Context API for managing global state.
• API Integration: Use APIs for grocery delivery and nutritional data.
• UI/UX Design: Improve the design with custom components and styles.

This is a starting point. Building a complete app requires further development, including backend logic, user authentication, data management, and more complex UI components.
