React-native-push-notification: null is not an object (evaluating 'RNPushNotification.presentLocalNotification')

  },
  "jest": {
    "preset": "react-native"
  },
  "private": true
}

React Native autolink is enabled and firebase messaging is set correctly.

Issue is When I'm logging the console.log(NativeModules.RNPushNotification), It is returning null,
I'm using expo's bare-workflow and when i try to manualy add RN...package in mainapplication.java's getPagackges, it shows that module is already registered. So the module is registered, but not showing up in NativeModules

Hi @charanjit-singh
Can you share the OS tested ? iOS ? Android ?
also take a look at:

It's on android

working great with create-react-native-app

I'm having the same problem. Works fine with plain react-native, but doesn't work in expo.

@pedrohba1 I got the exact same problem, did you figure out why it's not working in expo?

Is using packages that talk directly to the OS within expo not allowed, like notifications? I too am having the TypeError: null is not an object (evaluating 'RNPushNotification.presentLocalNotification') issue with this code:

import PushNotification, {
  PushNotificationObject,
} from 'react-native-push-notification';
[...]
const message: PushNotificationObject = {
  message: 'Test',
};
PushNotification.localNotification(message);

I also tried PushNotification.localNotification((notification) => console.log({notification}); with the same result.

I am running this via expo on an actual (older) Android 7 device, in case this is related to Android version. it's an old phone that I only use for testing. I have not manually linked anything so as to minimize issues with expo building things for me.

I'm dumb. Expo has this page on it's site: https://docs.expo.io/versions/latest/sdk/notifications/

I haven't got it working yet, but I'm getting farther than I was - FYI for all the expo users watching this thread.
