[firestore] Differences between official realtime updates and implementation

[DavidKuennen]

I noticed some differences / complications for the implementation of realtime updates between react-native-firebase and the official docs.

Example Code:

firebase
    .firestore()
    .collection('rooms')
    .where(`users.${userId}`, '==', true)
    .onSnapshot((docs) => {
        docs.docChanges.forEach((change) => {
            // this is where it's different.. see below
        });
    });

I noticed the following differences when using docs.docChanges:

Official	react-native-firebase
change.doc.data()	change.doc.data
change.doc.id	change.doc.path.split('/')[1] 😅

1. Application Target Platform: only tested on android
2. Development Operating System: Windows 10
3. Build Tools: Android Studio
4. React Native version: 0.48.4
5. RNFirebase Version: 3.0.2
6. Firebase Module: Firestore

@DavidKuennen Good spot! I've just resolved this and pushed up a change which will be released in our next patch release. In the meantime, you can try it out by doing the following:

npm install --save https://github.com/invertase/react-native-firebase.git

Great, thanks @chrisbianca.
I can use it like I do right now, so I'll wait for the next release and then just switch out a few lines of code. 😉
