IntrinsicDimension class

Inheritance

Constructors

IntrinsicDimension({Key? key, void listener(BuildContext context, double width, double height, Offset startOffset)?, required Widget builder(BuildContext context, double width, double height, Offset startOffset), bool rebuild = false})
IntrinsicDimension exposes a listener and a builder to get the dimensions of the widget returned from the builder.

Properties

builder → Widget Function(BuildContext context, double width, double height, Offset startOffset)
The builder callback function which is invoked on each widget build. The builder takes the BuildContext, the width, the height, and the startOffset from where the widget is drawn. The builder must return a widget. This is the widget from where is retrieved the width, height, and offset.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
listener → (void Function(BuildContext context, double width, double height, Offset startOffset)?)
The listener callback function which is invoked on each widget build. The listener takes the BuildContext, the width, the height, and the startOffset from where the widget is drawn. The listener returns nothing and it can be used to executes actions. For example, calling the setState method of an stateful widget and update the whole widget based on this widget dimensions.
final
rebuild → bool
The rebuild boolean allows to rebuild the widget every frame when it is set to true which updates the width, height, and offset offered by the listener and builder callback functions. This could be useful when changing the font size from the OS settings. If rebuild is false, changing the font size could change the widget size and offset and those properties won't be given again by this widget via listener or builder callback functions.
final
runtimeType → Type
A representation of the runtime type of the object.
