I saw this and JavaScript supports \'array-contains\' but what about flutter? Is there any way to query array that contains? Or flutter not support this?
The array-contains feature was added in version 0.8.0 of the FlutterFire library.
See https://github.com/flutter/flutter/issues/20489#issuecomment-419181186
Today I discover that they add array-contains to the plugin in version 0.8.0:

For iOS you should update the pod with pod update Firebase/Firestore
Best thing to do right now is to use a firebase cloud functions to achieve whatever isnt yet available for the flutter firestore library. Thats what i intend to do when its time to refactor.
