Memo Column

FdcMemoColumn extends the text-column contract but uses the memo editor. Use it for notes, descriptions, comments, and any value where multiline editing is expected.

Memo column sample
Loading FDC sample…
FdcGrid(
  dataSet: tickets,
  options: const FdcGridOptions(autoEdit: true),
  columns: const [
    FdcIntegerColumn(fieldName: 'ticket_id', width: 90, readOnly: true),
    FdcTextColumn(fieldName: 'subject', width: 180),
    FdcMemoColumn(
      fieldName: 'notes',
      width: 460,
      showCounter: true,
    ),
  ],
);

Key characteristics​

  • Binds to the same text-oriented data model as FdcTextColumn.
  • Uses memo-style editing suited to longer values.
  • Supports showCounter and counterStyle, just like text columns.
  • Works well in compact grids when the user edits the value in-place and then returns to the normal row height.

Counter support​

const FdcMemoColumn<dynamic>(
  fieldName: 'notes',
  label: 'Notes',
  width: 280,
  showCounter: true,
)

Layout guidance​

A grid row should remain a compact tabular surface. For very large documents or rich text, prefer opening a dedicated editor or detail panel rather than turning grid rows into large text canvases.
