full_pass_builder library

Classes

ChildrenGeometriesProvidedBuilder

A widget that exposes its layout calculation to an external visitor.

ChildrenGeometriesProviderParentData

ChildrenGeometriesProviderRenderObject

FullPassBuilder

A widget that makes it much easier to create custom layouts. Some of your layouts might require siblings, or children geometries to be present, but to get that, you'd usually have to go through all the boilerplate and imperative code with GlobalKey and addPostFrameCallback. With this, all you need is to just invoke the FullPassBuilder constructor, and all the information you need will just be there for you.

Layouter

A class that helps manage the positioning of children as well as providing some vital information obtained during performLayout

OffsetWrapper

A wrapper to help set the offset on the parent data

Typedefs

ChildBuilder = Widget Function(BuildContext context, BoxConstraints constraints)

ChildrenBuilder = List<Widget> Function(BuildContext context, BoxConstraints constraints)

ChildrenConstrainer = List<BoxConstraints> Function(BoxConstraints parentConstraints, List<RenderBox> childrenRenderBoxesBeforeApplyingConstraints)

Cheat by modifying the constraints for each of the children.

LayouterVisitor = Size Function(Layouter layouter)

This method accepts a layouter and returns the Size of the container of all widgets.

LayouterVisitorWithContext = Size Function(BuildContext context, Layouter layouter)

Same as LayouterVisitor, but with context
