Constructors
- OverflowBox({Key key, FractionalOffset alignment: FractionalOffset.center, double minWidth, double maxWidth, double minHeight, double maxHeight, Widget child })
-
Creates a widget that lets its child overflow itself.
Properties
- alignment → FractionalOffset
-
How to align the child.
read-only - maxHeight → double
-
The maximum height constraint to give the child. Set this to null (the default) to use the constraint from the parent instead.
read-only - maxWidth → double
-
The maximum width constraint to give the child. Set this to null (the default) to use the constraint from the parent instead.
read-only - minHeight → double
-
The minimum height constraint to give the child. Set this to null (the default) to use the constraint from the parent instead.
read-only - minWidth → double
-
The minimum width constraint to give the child. Set this to null (the default) to use the constraint from the parent instead.
read-only - child → Widget
-
The widget below this widget in the tree.
read-only, inherited - hashCode → int
-
Get a hash code for this object.
read-only, inherited - key → Key
-
Controls how one widget replaces another widget in the tree.
read-only, inherited - runtimeType → Type
-

RenderObjectWidgetto the givenRenderObject, which will be of the same type as returned by this object'screateRenderObject. -
createElement(
) → SingleChildRenderObjectElement -
RenderObjectWidgets always inflate to a
RenderObjectElementsubclass.inherited -
didUnmountRenderObject(
RenderObject renderObject) → void -
