The application crashes when the component is unmounted, caused by the fact that DeviceEventEmitter does not recognize that it has the removeListener method.

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-native-modal@9.0.0 for the project I'm working on.

DeviceEventEmitter.removeListener(

• "didUpdateDimensions",
• this.handleDimensionsUpdate
• ) => returns an error removeListener is not a function.

Here is the diff that solved my problem:
