ColumnSuper class
Given a list of children widgets, this will arrange them in a column. It can overlap cells, add separators and more.
Note this is not a substitute for Flutter's native Column, it doesn't try to
have a similar API, and it doesn't do all that Column does. In special,
Expanded and Flexible widgets don't work inside of ColumnSuper, and it will
overflow if the column is not big enough to fit its contents.
ColumnSuper is meant only for certain use cases where Column won't work,
like when you need overlapping cells or separators.

Constructors

ColumnSuper({Key? key, required List<
Widget?> children, double outerDistance = 0.0, double innerDistance = 0.0, bool invert = false, Alignment alignment = Alignment.center, Widget? separator, bool separatorOnTop = true, bool removeChildrenWithNoHeight = false}) - Given a list of children widgets, this will arrange them in a column. It can overlap cells, add separators and more.
Properties
- alignment → Alignment
-
How to align the cells horizontally,
if they are smaller than the available horizontal space.
final
-
children
→ List<
Widget> -
The widgets below this widget in the tree.
finalinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- innerDistance → double
-
The distance in pixels between the cells. It can be negative,
in which case the cells will overlap.
final
- invert → bool
-
If
truewill paint the cells that come later on top of the ones that came before. This is specially useful when cells overlap (negative innerDistance).final - key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- makeRefreshable → Widget
-
Available on Widget?, provided by the WidgetExtension extension
Make your any widget refreshable with RefreshIndicator on topno setter - outerDistance → double
-
The distance in pixels before the first and after the last widget.
It can be negative, in which case the cells will overflow the column
(without any overflow warnings).
final
- removeChildrenWithNoHeight → bool
-
If
true, children with zero height will not result in an extra innerDistance and separator. If all children have zero height, the outerDistance will also be removed. In other words, it's as if children with zero height are removed, except for the fact they still occupy width. The default isfalse.final - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- separator → Widget?
-
The separator is a widget which will be painted between each cell.
Its height doesn't matter, since the distance between cells is given by
innerDistance (in other words, separators don't occupy space).
The separator may overflow if its width is larger than the column's width.
final
- separatorOnTop → bool
-
If
true(the default) will paint the separator on top of the cells. Iffalsewill paint the separator below the cells.final
