SummerDataColumn class

Defines a column in SummerDataTable.

Width resolution rules:

  • width provided → fixed-size, participates in horizontal scrolling.
  • Otherwise → elastic, shares remaining viewport space by flex.

Constructors

SummerDataColumn({required Widget label, String? key, double? width, int flex = 1, double minWidth = 40.0, double maxWidth = double.infinity, bool sortable = false, List<bool> sortDirections = const [true, false], bool resizable = false, bool ellipsis = false, AlignmentGeometry alignment = Alignment.centerLeft, EdgeInsetsGeometry padding = const EdgeInsets.symmetric(horizontal: 12.0, vertical: 8.0), SummerColumnPin pin = SummerColumnPin.none, String? headerTooltip, List<SummerColumnFilter>? filters, bool filterMultiple = true, List<SummerDataColumn> children = const [], bool visible = true})

Properties

alignment → AlignmentGeometry
Default content alignment for cells and the header.
final
children → List<SummerDataColumn>
Child columns. When non-empty this column becomes a header-only group (antd/naive-style column grouping): its label spans all descendant columns in a merged header row, and body cells are rendered only for the (recursively) leaf columns beneath it.
final
ellipsis → bool
When true, overflowing cell text is ellipsized and a tooltip is shown.
final
filterMultiple → bool
Whether the filter dropdown allows multiple selections.
final
filters → List<SummerColumnFilter>?
Filter options for the header dropdown. null disables filtering.
final
flex → int
Flex weight for elastic columns. Ignored when width is set.
final
hashCode → int
The hash code for this object.
no setterinherited
headerTooltip → String?
Optional tooltip for the header cell.
final
isFixed → bool
Whether this column has a user-defined fixed width.
no setter
isGroup → bool
Whether this column is a header group (has children).
no setter
key → String?
Stable identifier. Used for sort, resize and filter keys.
final
label → Widget
Header content (usually a Text).
final
maxWidth → double
Maximum width.
final
minWidth → double
Minimum width.
final
padding → EdgeInsetsGeometry
Inner padding applied to header and body cells of this column.
final
pin → SummerColumnPin
Whether the column is frozen to a viewport edge.
final
resizable → bool
Whether the user can drag the column's right border to resize it.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sortable → bool
Whether the header is tappable to sort.
final
sortDirections → List<bool>
Permitted sort directions in click order, as a list where true = ascend and false = descend. Default [true, false] (asc → desc → unsort). Append nothing extra; a third click always returns to "unsorted".
final
visible → bool
Whether this column is rendered. When false, the column is skipped during layout and no header/body cells are created. Defaults to true.
final
width → double?
Fixed width in logical pixels. null → flex-sized.
final
