Warning: EventEmitter.removeListener('change', ...): Method has been deprecated.

I'm using RN 0.65.1 and install react-native-flash-message module on a newly created app. When ever I run the flash message I got this warning:

WARN EventEmitter.removeListener('change', ...): Method has been deprecated. Please instead useremove()on the subscription returned by EventEmitter.addListener.

A friend of mine using the same module but his app RN is a bit older (0.64.2)

@imomer I have got Same Issue with the react-native version - 0.65.1, react-native-flash-message - 0.1.15

I have a same issue:

EventEmitter.removeListener('change', ...): Method has been deprecated. Please instead use `remove()` on the subscription returned by `EventEmitter.addListener`.

Environment:

"react": "17.0.2",
"react-native": "0.65.1",
"react-native-flash-message": "^0.1.23"

I search in source code and found this section FlashMessageWrapper.js:

componentDidMount() {
  Dimensions.addEventListener("change", this.handleOrientationChange);
}
componentWillUnmount() {
  Dimensions.removeEventListener("change", this.handleOrientationChange);
}

I think this is causing the warning

This patch worked for me.

Hi folks,

The last update published in NPM had a fix to this event warning.

Thanks for the reporting ;)
