- Before running the app make sure you have import Collection json in Firestore database which we have provided.
- Before import json in firestore database remember to give rule permission or create Firestore Data. See the Firebase Rules for create Firestore Database and how to give permission in firebase.

As you have know for App Run we need some setting data from firbase and we run the app diectly without add any config data

While app run if you face any query like this :

" The following RangeError was thrown building StreamBuilder>>(dirty, state: _StreamBuilderBaseState>, AsyncSnapshot >>>#ac398): RangeError (index): Invalid value: Valid value range is empty: 0"

Follow the steps below to add manually Required collection in firebase :

1. config - [REQUIRED] - Need to add manually
   1. usageControls
   2. userAppSettings
   3. agoraToken
   

   Let see detail about all the collections.
