select property

SelectFn<TQueryData, TData>? get select

Narrows the data the observer reports: while the selection stays equal, the reported data keeps its instance (unless structuralSharing is switched off). The rest of the result (fetchStatus, dataUpdatedAt, …) still changes, and listeners are told of that. No default: null on a QueryObserverOptions, never on a QuerySelectOptions.

Implementation

SelectFn<TQueryData, TData>? get select;
