Cannot support 2 or more groups

[yiutsunchan]

Please help

I tried to create more than 1 group to the firebase via the "group-create.js" script
The app show this error.

Here is the error

════════ Exception caught by widgets library ═══════════════════════════════════
The following NoSuchMethodError was thrown building StoreConnector<AppState, ChannelScreenViewModel>(dependencies: [StoreProvider]):

Pretty sure this is unimplemented by them, but you can create another group with: Firestore.instance.collection('groups').add({<Map>})

@xJon Agreed that they haven't implemented the "Create Group" UI within the app.
However, I used the script "group-create.js" to create 2 groups and the app crash because of this.

I'm not sure whether the script was intended for that; I'm not an expect in JavaScript nor did I read the script itself, but I do know that it's rather simple to add a new group with the code I quoted above.
