toJson abstract method
Converts the object to a Firestore-compatible map.
Returns a Map with string keys and dynamic values that can be directly written to Firestore. All complex objects should be converted to basic Firestore-supported types.
Example:
@override
Map<String, dynamic> toJson() => {
'field1': value1,
'field2': value2,
};
Implementation
Map<String, dynamic> toJson();
