Constructors

ElCustomMultiChildLayoutWidget({Key? key, double width = double.infinity, double height = double.infinity, required MultiChildLayoutDelegate delegateBuilder(UpdateCustomLayoutSize updateSize, bool isReBuild), required List<
Widget> children}) -
简单地扩展自定义多子组件布局，CustomMultiChildLayout 只能预先设置父级盒子的尺寸，
但有时我们希望先测量所有子元素，再决定父级的大小，这就是该组件的作用
const
Properties
-
children
→ List<
Widget> -
子组件集合，和 CustomMultiChildLayout 一样，你必须使用 LayoutId 标识它们
final
- delegateBuilder → MultiChildLayoutDelegate Function(UpdateCustomLayoutSize updateSize, bool isReBuild)
-
处理多个子部件布局逻辑，在此基础上传递了两个参数：
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- height → double
-
预定父盒子的高度，默认无限，当处于滚动容器中，你必须预先设置它
final
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- width → double
-
预定父盒子的宽度，默认无限，当处于滚动容器中，你必须预先设置它，
通常情况下，每个子元素应该设置预期的最大宽度，然后根据子元素数量 * 最大宽度
final
