我想使抽屉的Flutter滚动，使用户可以看到所有的数据在一个抽屉。我调用endDrawer为：
endDrawer: ExperienceCustomDrawer()ExperienceCustomDrawer类是：
import 'package:flutter/material.dart';
class ExperienceCustomDrawer extends StatelessWidget {
ExperienceCustomDrawer({
super.key,
});
@override
Widget build(BuildContext context) {
return Drawer(

}我尝试将第一个容器 Package 在singleChildScrollView和ListView中，但它不起作用。做这些修改会导致抛出渲染errors.as你可以看到：
return Drawer(
width: MediaQuery.of(context).size.width * 0.6,
child:Container(
color: Colors.black,
child: SingleChildScrollView(
scrollDirection: Axis.vertical,
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
],
),
),
)
);误差是：
======== Exception caught by rendering library =====================================================
The following assertion was thrown during performLayout():
RenderFlex children have non-zero flex but incoming height constraints are unbounded.
When a column is in a parent that does not provide a finite height constraint, for example if it is in a vertical scrollable, it will try to shrink-wrap its children along the vertical axis. Setting a flex on a child (e.g. using Expanded) indicates that the child is to expand to fill the remaining space in the vertical direction.
These two directives are mutually exclusive. If a parent is to shrink-wrap its child, the child cannot simultaneously expand to fit its parent.
Consider setting mainAxisSize to MainAxisSize.min and using FlexFit.loose fits for the flexible children (using Flexible rather than Expanded). This will allow the flexible children to size themselves to less than the infinite remaining space they would otherwise be forced to take, and then will cause the RenderFlex to shrink-wrap the children rather than expanding to fit the maximum constraints provided by the parent.
If this message did not help you determine the problem, consider using debugDumpRenderTree():
https://flutter.dev/debugging/#rendering-layer
http://api.flutter.dev/flutter/rendering/debugDumpRenderTree.html
The affected RenderFlex is: RenderFlex#dc3b5 relayoutBoundary=up3 NEEDS-LAYOUT NEEDS-PAINT NEEDS-COMPOSITING-BITS-UPDATE
parentData: offset=Offset(0.0, 0.0) (can use size)
constraints: BoxConstraints(0.0<=w<=697.2, 0.0<=h<=Infinity)
size: MISSING
direction: vertical
mainAxisAlignment: start
mainAxisSize: max
crossAxisAlignment: center

您正在尝试在
SingleChildScrollView中添加带有flexible小部件的column，这导致了问题。您可以
1.删除
flexible小部件并使用SingleChildScrollViewPackage 列或
1.删除
column和flexible小部件，并将列替换为ListView
