Why am I seeing a `TypeError: Cannot read property 'init' of null` error when using the Pushwoosh React Native plugin in my Expo project?

This error typically occurs in Expo projects when the native modules required by the Pushwoosh plugin have not been properly generated or linked. This often happens if you haven't run the prebuild command before attempting to build or run your application with native capabilities.

To resolve this issue, you need to ensure the native project files are generated and configured correctly. Follow these steps:

1. Open your terminal and navigate to your project's root directory.
2. Run the prebuild command. This command generates the native ios and android project directories if they don't already exist, or updates them to include necessary native module configurations:

   npx expo prebuild
   

3. After the prebuild process completes successfully, you can then build and run your application on a simulator/emulator or a physical device using the following commands:
   • For iOS:

     npx expo run:ios
     

   • For Android:

     npx expo run:android
     

Running npx expo prebuild ensures that all necessary native code for the Pushwoosh plugin is generated and linked into your native iOS and Android projects. This allows the init function and other native functionalities of the plugin to be available at runtime, preventing the TypeError.
