Integer Column

FdcIntegerColumn is the standard choice for whole-number values. It supports normal integer editing, optional sign policy, display-only prefixes/suffixes, and the same lookup integration available on text columns.

FdcGrid(
  dataSet: stockRows,
  options: const FdcGridOptions(autoEdit: true),
  columns: [
    FdcIntegerColumn(
      fieldName: 'warehouse_id',
      width: 120,
      lookupIcon: Icons.manage_search,
      onLookup: openWarehouseLookup,
    ),
    const FdcIntegerColumn(
      fieldName: 'units_in_stock',
      width: 120,
      allowNegative: false,
      suffixText: ' pcs',
    ),
    const FdcIntegerColumn(
      fieldName: 'lead_days',
      width: 110,
      suffixText: ' days',
    ),
  ],
);

Key characteristics​

  • Binds to FdcIntegerField.
  • Supports allowNegative when the field should reject negative input.
  • Supports display-only prefixText and suffixText.
  • Supports onLookup, making it suitable for numeric code or ID resolution scenarios.

Display formatting​

const FdcIntegerColumn<dynamic>(
  fieldName: 'lead_days',
  label: 'Lead time',
  suffixText: ' days',
)

Affixes are presentation-only metadata. They do not change parsing, sorting, filtering, storage, or aggregates.

Lookup scenarios​

Integer lookup is useful for values such as warehouse IDs, account numbers, or reference codes. The sample above shows a simple lookup action you can trigger immediately.
