问题:

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?

回答1:

The array-contains feature was added in version 0.8.0 of the FlutterFire library.

The array-contains feature has not yet been surfaced in 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.
