Firebase.database().push does not return key

Issue

I'm currently using redux saga and react native firebase however after pushing an object nothing is returned in v2.2 it would return a result where I could get a query back however it seems its broken in this case unless im doing something wrong?
const result = yield call([dbRef, dbRef.push], () => eventObj);

Environment

1. Application Target Platform:
   Both

2. Development Operating System:
   macos

3. Build Tools:
   xcode

4. React Native version:
   0.49.3

5. RNFirebase Version:

Hello, not sure how saga works but are you expecting it to return a promise here?

@MaithaM1 There was a change in v3 to push to bring it in line with the Web SDK. Details are in this issue: #147

@Salakar can provide some more information as he made the change.

@MaithaM1 push promise no longer resolves with the reference, you need to change your code to something like the following:

const thenableRef = dbRef.push();

// new ref is an instance of DatabaseReference with .then() support, just like the web sdk
console.log(newRef.key)
console.log(newRef.path)

// set the value if needed
const pushResult = await thenableRef.set({ some: 'value' });

See the official web sdk reference guide: https://firebase.google.com/docs/reference/js/firebase.database.ThenableReference#push
