reduce method

  1. @override
CoreState reduce()

The reduce method is the action reducer. It may read the action state, the store state, and then return a new state (or null if no state change is necessary).

It may be synchronous (returning AppState or null) or async (returning Future<AppState> or Future<null>).

The StoreConnectors may rebuild only if the reduce method returns a state which is both not null and different from the previous one (comparing by identical, not equals).

Implementation

@override
CoreState reduce() {
  final PatientPayload? patientPayload =
      state.clinicalState?.patientPayload?.copyWith.call(
    patientRecord: patientEdge?.node,
    hasOpenEpisodes: patientEdge?.hasOpenEpisodes,
  );

  final ClinicalState? clinicalState =
      state.clinicalState?.copyWith.call(patientPayload: patientPayload);

  final CoreState newState =
      state.copyWith.call(clinicalState: clinicalState);
  return newState;
}
