PlutoAggregateColumnFooter class

Widget for outputting the sum, average, minimum, and maximum values of all values in a column.

Example) PlutoColumn.footerRenderer Implement column footer as return value of callback

PlutoColumn(
  title: 'column',
  field: 'column',
  type: PlutoColumnType.number(format: '#,###.###'),
  textAlign: PlutoColumnTextAlign.right,
  footerRenderer: (rendererContext) {
    return PlutoAggregateColumnFooter(
      rendererContext: rendererContext,
      type: PlutoAggregateColumnType.sum,
      format: 'Sum : #,###.###',
      alignment: Alignment.center,
    );
  },
),

PlutoAggregateColumnFooter You can also return a Widget you wrote yourself instead of a widget. However, you must implement the process of updating according to the value change yourself.
