SliverMultiBoxAdaptorElement constructor Null safety
- SliverMultiBoxAdaptorWidget widget,
- {bool replaceMovedChildren = false}
Creates an element that lazily builds children for the given widget.
If replaceMovedChildren is set to true, a new child is proactively
inflate for the index that was previously occupied by a child that moved
to a new index. The layout offset of the moved child is copied over to the
new child. RenderObjects, that depend on the layout offset of existing
children during RenderObject.performLayout should set this to true
(example: RenderSliverList). For RenderObjects that figure out the
layout offset of their children without looking at the layout offset of
existing children this should be set to false (example:
RenderSliverFixedExtentList) to avoid inflating unnecessary children.
Implementation
SliverMultiBoxAdaptorElement(SliverMultiBoxAdaptorWidget super.widget, {bool replaceMovedChildren = false})
: _replaceMovedChildren = replaceMovedChildren;
