@override
DataGridState<T>? apply<T extends DataGridRow>(EventContext<T> context) {
  if (context.state.selection.mode == mode) {
    return null;
  }

  return context.state.copyWith(
    selection: context.state.selection.copyWith(
      mode: mode,
      selectedRowIds: {},
      selectedCellIds: {},
      focusedRowId: null,
    ),
  );
}
