How Do Self-Handled In-Apps Work in React Native?

The self-handled in-app functionality in React Native ensures that new event listeners are configured only after any active callback is completed. This approach ensures that events are handled individually, maintaining the correct order and execution of callbacks.

Here’s how it works:

• Single Invocation Scenario
  Where the self-handled in-app method is called once in the app, the event listener captures and logs the payload a single time. The following are example snippets of the implementation:
• Multiple Invocation Scenario
  If the self-handled in-app method is called multiple times in quick succession, React Native’s event-handling model ensures the listener still responds only once. For example:

This orderly event handling is crucial for keeping the application stable and predictable. By processing each self-handled in-app message one at a time, developers can ensure every message is managed properly, improving the overall user experience.
