TextField widgets require a Material widget ancestor. In material design, most widgets are conceptually “printed” on a sheet of material. In Flutter’s material library, that material is represented by the Material widget. It is the Material widget that renders ink splashes, for instance. Because of this, many material library widgets require that there be a Material widget in the tree above them. To introduce a Material widget, you can either directly include one, or use a widget that contains Material itself, such as a Card, Dialog, Drawer, or Scaffold. The specific widget that could not find a Material ancestor was: TextField The ancestors of this widget were: … Container Expanded Row InputPage Semantics … The relevant error-causing widget was: 原代码: @override Widget build(BuildContext context) { return Row( children: [] ); 解决方案: 添加Scaffold() @override Widget build(BuildContext context) { return Scaffold( body: Row( children: [ ], ), ); } This widget has been unmounted, so the State no longer has a context (and should be considered defunct) showDialog( context: context, barrierDismissible: false, // user must tap button! builder: (BuildContext context) { return AlertDialog( title: null, content: SingleChildScrollView( child: ListBody( children:[], )), actions: FlatButton( child: Text('关闭'), onPressed: () { Navigator.of(context).pop(); }, 自我介绍一下，小编13年上海交大毕业，曾经在小公司待过，也去过华为、OPPO等大厂，18年进入阿里一直到现在。 深知大多数初中级Android工程师，想要提升技能，往往是自己摸索成长或者是报班学习，但对于培训机构动则近万的学费，着实压力不小。自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！ 因此收集整理了一份《2024年Android移动开发全套学习资料》，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友，同时减轻大家的负担。 既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，基本涵盖了95%以上Android开发知识点，真正体系化！ 由于文件比较大，这里只是将部分目录截图出来，每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频，并且会持续更新！ 如果你觉得这些内容对你有帮助，可以扫码获取！！（备注：Android） 写在最后 最后我想说：对于程序员来说，要学习的知识内容、技术有太多太多，要想不被环境淘汰就只有不断提升自己，从来都是我们去适应环境，而不是环境来适应我们！ 这里附上上述的技术体系图相关的几十套腾讯、头条、阿里、美团等公司2021年的面试题，把技术点整理成了视频和PDF（实际上比预期多花了不少精力），包含知识脉络 + 诸多细节，由于篇幅有限，这里以图片的形式给大家展示一部分。 相信它会给大家带来很多收获： 当程序员容易，当一个优秀的程序员是需要不断学习的，从初级程序员到高级程序员，从初级架构师到资深架构师，或者走向管理，从技术经理到技术总监，每个阶段都需要掌握不同的能力。早早确定自己的职业方向，才能在工作和能力提升中甩开同龄人。 《Android学习笔记总结+移动架构视频+大厂面试真题+项目实战源码》，点击传送门即可获取！ 1817612430)] [外链图片转存中…(img-D0Stict6-1711817612431)] 既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，基本涵盖了95%以上Android开发知识点，真正体系化！ 由于文件比较大，这里只是将部分目录截图出来，每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频，并且会持续更新！ 如果你觉得这些内容对你有帮助，可以扫码获取！！（备注：Android） 写在最后 最后我想说：对于程序员来说，要学习的知识内容、技术有太多太多，要想不被环境淘汰就只有不断提升自己，从来都是我们去适应环境，而不是环境来适应我们！ 这里附上上述的技术体系图相关的几十套腾讯、头条、阿里、美团等公司2021年的面试题，把技术点整理成了视频和PDF（实际上比预期多花了不少精力），包含知识脉络 + 诸多细节，由于篇幅有限，这里以图片的形式给大家展示一部分。 相信它会给大家带来很多收获： [外链图片转存中…(img-YE4UKwnQ-1711817612431)] [外链图片转存中…(img-gs48K5dv-1711817612431)] 当程序员容易，当一个优秀的程序员是需要不断学习的，从初级程序员到高级程序员，从初级架构师到资深架构师，或者走向管理，从技术经理到技术总监，每个阶段都需要掌握不同的能力。早早确定自己的职业方向，才能在工作和能力提升中甩开同龄人。 《Android学习笔记总结+移动架构视频+大厂面试真题+项目实战源码》，点击传送门即可获取！ 柚子快报激活码778899分享：Flutter 开发错误集合一 参考文章
