Firestore get for non-existent values (DocumentSnapshot)

[tgpsantos]

Hello all,

When we try to get a field that does not exist in a DocumentSnapshot an exception is thrown.

DocumentSnapshot doc = (...)
String field = doc.get('non_existent_field')

Error: Bad state: field does not exist within the DocumentSnapshotPlatform

In order to get fields that might be null, we can do the following

DocumentSnapshot<Map<String, dynamic>> doc = (...)
String field = doc.data()['non_existent_field']

It's a bit of a pain having to call <Map<String, dynamic>> every time I want to instantiate a DocumentSnapshot, so I was wondering if it's possible to have a null check in the get('field') method that would return null if the field didn't exist. Or is there a better way besides this one?
