Flutter中CarouselSlider下方文本不显示及添加分隔线问题咨询

• 自定义的buildText方法从未被加入到页面组件树中，Flutter不会主动渲染未被调用的组件方法
• buildText内部错误嵌套了额外的Scaffold，页面已经存在顶层Scaffold，重复嵌套会导致布局异常
• 原页面body仅直接承载CarouselSlider，没有使用垂直布局容器承载轮播下方的其他组件
• CarouselSlider放入Column时未指定固定高度，会触发布局边界溢出报错

将body根布局调整为Column实现垂直排布，依次放入轮播组件、分隔线、标题文本即可：

import 'package:flutter/material.dart';
import 'package:carousel_slider/carousel_slider.dart';

class HomeScreen extends StatelessWidget {
  final List<String> imageList = [

}

• 轮播高度可直接修改CarouselOptions的height参数适配设计需求
• 分隔线的粗细、颜色、左右边距可修改Divider组件的对应属性
• 组件之间的留白大小可调整对应SizedBox的height参数
• 文本样式、对齐方式、边距可直接修改Text和外层Padding的参数
