getDatum method

@override Future<Datum?> getDatum()

Subclasses should implement / override this method to collect the Datum. This method will be called every time data has been buffered for a duration and should return the final Datum for the buffered data.

Can return null if no data is available. Can return an ErrorDatum if an error occurs.

Implementation

@override
Future<Datum?> getDatum() async => _datum;
