Description

Steps to reproduce:

  • Create a new "Native view" project via npx create-react-native-library@latest test
  • cd example && yarn start
  • run android app
  • perform any modification to the src/index.tsx where the custom view bridge is defined, for example add a simple newline at the end of the file

Actual:
The error:

Invariant Violation: Tried to register two views with the same name TestView, js engine: hermes 

is displayed in the console and in the Android app.

The error points to the requireNativeComponent line of the following code in src/index.tsx:

export const TestView = UIManager.getViewManagerConfig(ComponentName) != null ? requireNativeComponent<TestProps>(ComponentName) : () => { throw new Error(LINKING_ERROR); }; 

Expected:
no errors should be shown.
