Example: Instead of using native date pickers for each platform, consider using a cross-platform date picker component that provides a consistent experience on both iOS and Android.

3. Leverage Native Modules When Necessary

While cross-platform frameworks aim to provide a unified development experience, there might be instances where you need to access platform-specific features or functionalities. In such cases, leverage native modules to bridge the gap between the cross-platform code and the native platform.

Identify Platform-Specific Requirements: Determine if your application requires access to specific hardware features or native APIs.
Create Native Modules: Develop native modules using the native languages and tools for each platform (e.g., Swift/Objective-C for iOS, Java/Kotlin for Android).
Expose Native Functionality: Expose the functionality of your native modules to your cross-platform code.
Handle Platform-Specific Logic: Implement conditional logic to handle platform-specific behavior when using native modules.

Example: If you need to access the device's accelerometer, you might need to create a native module to access the platform-specific accelerometer API.

4. Optimize Performance

Performance is critical for user satisfaction. Optimize your application to ensure smooth and responsive performance across all platforms.

Minimize Network Requests: Reduce the number of network requests to improve loading times.
