operator [] method
Gets a nested field by String or FieldPath
from this DocumentSnapshot
.
Data can be accessed by providing a dot-notated path or FieldPath
which recursively finds the specified data. If no data could be found
at the specified path, a StateError will be thrown.
Implementation
@override
dynamic operator [](Object? field) => super.noSuchMethod(Invocation.method(#[], [field]));
