Platform-Specific Code	Contains platform-specific functionality, like native API access, that cannot be abstracted across platforms.

Integrating Native Features and APIs in Cross-Platform Mobile Apps

Cross-platform mobile development has gained immense popularity due to its cost-effectiveness and broad audience reach. However, when it comes to leveraging platform-specific functionality, integrating native features becomes a significant challenge. This integration allows developers to enhance the user experience by utilizing hardware capabilities and device-specific APIs that are not inherently supported by cross-platform frameworks.

Native features such as access to the camera, GPS, sensors, or push notifications often require direct communication with the operating system’s APIs. By bridging these capabilities into cross-platform apps, developers can create more dynamic, feature-rich applications. The process usually involves using plugins, modules, or custom code to call native functionality while maintaining a shared codebase.

Methods of Integration

• Plugin-based approach: This is the most common method where ready-made plugins or libraries are used to access device features.
• Native Modules: Custom code is written to create platform-specific modules for features that are not available through plugins.
• Custom Bridging: A more advanced method where developers create a bridge between the native and cross-platform codebase to call specific APIs.

Native features, when properly integrated, provide a seamless experience for end-users while maintaining the benefits of cross-platform development.
