filterOperatorLabel abstract method

String filterOperatorLabel(
  1. String operatorKey
)

Returns the localised label for a filter operator key.

operatorKey matches TablexFilterOperator.labelKey — e.g. 'equals', 'greaterThan', 'isEmpty'. Falls back to operatorKey itself for unknown keys so new operators degrade gracefully.

Implementation

String filterOperatorLabel(String operatorKey);
