React-native-firebase: Request Permission

[callmejm]

How can request permission again next time, when user reject the permission.

firebase.messaging().hasPermission()
.then(enabled => {
  if (enabled) {
    // user has permissions
    console.log("have");
  } else {
    // user doesn't have permission
    console.log("no have");
    firebase.messaging().requestPermission()
    .then(() => {
      // User has authorised  
    })
    .catch(error => {
      // User has rejected permissions  
    });
  } 
});

This should work.

export default class fcmHandler extends React.PureComponent {

componentDidMount() {

firebase.messaging()
    .hasPermission()
    .then(enabled => {
        if (!enabled) {
            this._getPermission();
        }
    });
}

 _getPermission = () => {
    firebase.messaging()
        .requestPermission()
        .catch(error => {
            // User has rejected permissions
            this._getPermission();
        });
};

}

Thanks @judemanutd

It's also worth noting that on iOS, if the user rejects permissions, you will have to direct them to the notification settings page in the OS to add the permissions. Prompting them for permissions again will not work as it's blocked by the OS.

You'll have to do this within your app, as it's not part of the library.

Please help, how can I do this?

Use Linking:
Linking.openURL(app-settings://notification/${yourBundleIdentifierHere});
