OverflowBoxModifier class

A widget that imposes different constraints on its child than it gets from its parent, possibly allowing the child to overflow the parent.

• SizedOverflowBox, a widget that is a specific size but passes its original constraints through to its child, which may then overflow.
• ConstrainedBox, a widget that imposes additional constraints on its child.
• UnconstrainedBox, a container that tries to let its child draw without constraints.

OverflowBoxModifier({Key? key, Widget? child, Key? modifierKey, AlignmentGeometry alignment = Alignment.center, double? minWidth, double? maxWidth, double? minHeight, double? maxHeight})

Creates a widget that lets its child overflow itself.

Properties

alignment → AlignmentGeometry

How to align the child.

final

hashCode → int

The hash code for this object.

no setter, inherited

key → Key?

maxHeight → double?

The maximum height constraint to give the child. Set this to null (the default) to use the constraint from the parent instead.

final

maxWidth → double?

The maximum width constraint to give the child. Set this to null (the default) to use the constraint from the parent instead.

final

minHeight → double?

The minimum height constraint to give the child. Set this to null (the default) to use the constraint from the parent instead.

final

minWidth → double?

The minimum width constraint to give the child. Set this to null (the default) to use the constraint from the parent instead.
