各位开发者晚上好，

我正在尝试为我的父容器找到一种将其高度设置为等于子文本小部件内容的方法。Text 小部件中的文本 (textDes) 正在发生变化。它可以是短的或长的，因此我不能将高度设置为一个特定的数字，比如 1400，因为它看起来很难看。

请善待并帮助我，尝试几个小时。

将您的 Text 小部件包装在 Expanded 中并删除 1400 的硬编码高度

                          Expanded(
                            child: Text(
                              textDes,
                              style: TextStyle(
                                fontSize: 16.0,
                                color: Color.fromRGBO(117, 117, 117, 1),
                              ),
                            ),
                          ),

希望能帮助到你！！

经过长时间的工作，这就是我想出的方法。

import 'package:angelbay_bungalows/screens/overview.dart';
import 'package:angelbay_bungalows/widgets/drawer.dart';
import 'package:flutter/material.dart';

class Amenities extends StatelessWidget {
  final String titleTop;
  final String textDes;
  final String img;

  Amenities(this.titleTop, this.textDes, this.img);

  final GlobalKey<ScaffoldState> scaffoldKey = GlobalKey<ScaffoldState>();
  @override
  Widget build(BuildContext context) {
    var screenSize = MediaQuery.of(context).size;

    return Scaffold(
      key: scaffoldKey,
      drawer: AppDrawer(),
      body: Container(
        color: Color.fromRGBO(216, 216, 216, 1),
        child: Stack(
          // overflow: Overflow.visible,
          children: <Widget>[
            Image.asset(
              "$img",
              height: 400,
              width: screenSize.width,
              fit: BoxFit.cover,
            ),
            Positioned(
