validateSchema method

@override void validateSchema()

Validates runtime schema invariants that cannot rely on debug-only asserts.

Field definitions keep const constructors for ergonomic schema declarations, so the dataset calls this during schema indexing to enforce public field metadata rules in debug and release builds.

Implementation

@override
void validateSchema() {
  super.validateSchema();
  if (scale < 0 || scale > 7) {
    throw ArgumentError.value(
      scale,
      'scale',
      'FdcTimeField "$name" scale must be in range 0..7.',
    );
  }
}
