            PlutoColumn(
              title: 'Column $i',
              field: 'column$i',
              minWidth: 100,
              type: PlutoColumnType.text(),
              titlePadding: EdgeInsets.zero,
            ),
        ],
        rows: const [],
        onLoaded: (event) {
          event.stateManager;

          for (final column in event.stateManager.columns) {

Any news on what could cause this? This could be a make or break problem for my application
