• Setting Up the Development Environment: Installing Node.js, npm, React Native CLI, and setting up Android Studio and Xcode (for macOS users).
• JavaScript Essentials: Quick recap of JavaScript fundamentals, including variables, data types, functions, and ES6 features like arrow functions, destructuring, and modules.
• Introduction to React: Understanding the core concepts of React, including components, JSX, props, and state.
• Creating Your First React Native App: Building a simple app to learn the structure of a React Native project and how it runs on emulators or real devices.

2. React Native Components and Layouts

Key Topics:

• Core Components: Introduction to basic React Native components such as View, Text, Image, ScrollView, TextInput, Button, and TouchableOpacity.
• Styling in React Native: Styling with StyleSheet, understanding the differences between web and mobile styling, using flexbox for layouts.
• Handling User Input: Capturing user input with TextInput, implementing form validation, and handling form submissions.
• Handling Touch Events: Using TouchableOpacity, TouchableHighlight, and Pressable to handle user interactions.
• React Native Navigation: Introduction to navigation concepts in React Native and using React Navigation to manage app routes and screens.

3. State Management in React Native

Key Topics:

• React State: Understanding the useState hook and managing state within functional components.
• Props vs. State: Understanding the difference between props (data passed down to components) and state (data managed within a component).
• Context API: Introduction to the Context API for sharing state across components without passing props manually.
• State Management Libraries: Introduction to Redux for state management, including actions, reducers, and store.
• Redux with React Native: Integrating Redux into React Native apps for global state management and using react-redux for connecting components.

4. Working with APIs and Networking

Key Topics:

• Fetching Data with Fetch API: Making HTTP requests using the fetch API and handling JSON data.
• Axios for HTTP Requests: Using axios for making HTTP requests and simplifying error handling and response parsing.
• Handling Async Operations: Understanding asynchronous programming with async and await for working with promises.
• Error Handling: Implementing error handling for API requests and managing loading states.
• Integrating with REST APIs: Making API calls to consume data from public APIs and displaying it within the app.

5. Working with Databases and Local Storage

Key Topics:

• AsyncStorage: Using React Native’s AsyncStorage for storing key-value pairs locally.
• SQLite Database: Integrating SQLite with React Native to store structured data in a local database.
• Realm Database: Introduction to Realm, an alternative NoSQL database for React Native with simple data modeling.
• Offline Data Sync: Implementing offline-first functionality and synchronizing data when the network is available.
• File System Access: Reading and writing files to the device’s local file system.

6. Handling Navigation in React Native

Key Topics:

• Navigation Basics: Introduction to navigation in React Native, focusing on stack, tab, and drawer navigators.
• React Navigation: Using the React Navigation library for managing different screens and routes in the app.
• Navigating Between Screens: Passing data between screens and handling deep linking for direct navigation to specific parts of the app.
• Navigation Patterns: Using modal navigation, nested navigators, and conditional navigation flows based on user actions or app state.
• Navigation Customization: Customizing header styles, tab bar, and transitions between screens.

7. Animations in React Native

Key Topics:

• Basic Animations: Using Animated API for basic animations like fades, slides, and scaling.
• Animated API: Introduction to the Animated library, including Animated.View, Animated.Text, and how to create smooth animations.
• Gesture Handler: Implementing gestures with react-native-gesture-handler and handling swipe, pinch, and drag gestures.
• Animation Libraries: Using libraries like Lottie for animations and React Native Reanimated for advanced animation control.
• Complex Animations: Creating complex, coordinated animations (e.g., sequence, parallel animations) for fluid and engaging UI experiences.

8. Debugging and Testing in React Native

Key Topics:

• Debugging Tools: Using the React Native Debugger, Chrome DevTools, and React Developer Tools for debugging JavaScript code and components.
• Error Handling: Implementing try/catch blocks, managing exceptions, and debugging common React Native errors.
• Unit Testing: Introduction to unit testing using libraries like Jest for testing JavaScript functions and components.
• UI Testing: Using react-native-testing-library to write UI tests for React Native components.
• End-to-End Testing: Implementing end-to-end testing with tools like Detox to simulate user interactions and verify app functionality.

9. Performance Optimization in React Native

Key Topics:

• Memory Management: Identifying memory leaks and optimizing memory usage in React Native apps.
• Reducing Rendering Time: Techniques for optimizing React Native components to minimize unnecessary re-renders.
• List Optimization: Using FlatList and SectionList efficiently to render large datasets with optimizations like pagination and lazy loading.
• Image Optimization: Optimizing images for different screen sizes and resolutions using libraries like react-native-fast-image.
• Profiling and Monitoring: Using React Native’s built-in performance profiling tools and third-party libraries to monitor app performance.

10. Publishing and Maintaining React Native Apps

Key Topics:

• App Signing and Build Process: Preparing React Native apps for release, including signing APKs for Android and IPAs for iOS.
• Publishing to Google Play Store: Steps for submitting an app to the Google Play Store, including app details, metadata, and versioning.
• Publishing to Apple App Store: Steps for submitting an app to the Apple App Store, including app reviews, setting up provisioning profiles, and dealing with App Store guidelines.
• CI/CD for React Native: Setting up continuous integration and deployment pipelines with tools like Bitrise, GitHub Actions, or CircleCI.
• App Maintenance and Updates: Managing app updates, fixing bugs, and handling user feedback after release.
