How to Communicate with the native component from React native using bridge

To communicate with native components using a bridge, you'll typically need to follow a few steps. Here's a general overview of the process

Set up the bridge: Depending on the platform you're working with (e.g., Android, iOS, React Native), you'll need to set up a bridge that enables communication between the native code and your JavaScript code.

Define the communication protocol: Determine how you want to exchange data and messages between the native components and your JavaScript code. This could involve defining methods, events, or callbacks that can be accessed through the bridge.

implement the native component: Write the native code component using the appropriate programming language (e.g., Java or Kotlin for Android, Objective-C or Swift for iOS). This component should expose the methods or events you want to communicate with from JavaScript.

Expose the native component to JavaScript: Use the bridge to expose the native component to your JavaScript code. This typically involves registering the component with the bridge and providing a unique identifier.

Access the native component from JavaScript: Once the native component is exposed, you can access its methods or listen to its events from your JavaScript code. This is typically done using the bridge's API, which allows you to call native methods or subscribe to events.

Handle communication: Use the bridge to send messages or data between the native component and your JavaScript code. This could involve invoking native methods, passing parameters, receiving and processing callbacks, or emitting events.

It's important to note that the exact implementation details may vary depending on the platform and bridge you're using. For example, React Native provides its own bridge called "React Native Bridge," while frameworks like Flutter or Xamarin have their own mechanisms for native code integration.

Attaching the few doc's which visualize how the bridge is created.

The above image shows both the meta and header files created successfully, Now you can connect the those bridge using native modules from the React.

Thanks for Reading....
