Bigquery API fails: type 'Null' is not a subtype of type 'Object' in type cast #306

Closed keyonghan closed 3 years ago

keyonghan commented 3 years ago

We (flutter/cocoon) recently migrated our backend to null safety, and started hitting below error (with googleapis version 3.0.0). I guess the culprit is: https://github.com/google/googleapis.dart/blob/master/generated/googleapis/lib/bigquery/v2.dart#L11097 where v: _json.containsKey('v') ? _json['v'] as core.Object : null should be updated to v: _json.containsKey('v') ? _json['v'] as core.Object? : null to consider the value null case.
