问题 I am battling this DropDownItem box error, everything seems to work, but pops up the yellow out of bounds while it loads. Tried several things and can not get it resolved. I have this code for my Widget . @override Widget build(BuildContext context) { var _children = <Widget>[ !_createNew ? _referrerPractice() : _referrerCreate(), ]; return new Scaffold( appBar: new AppBar( title: new Text(widget.title), ), body: new Column( mainAxisSize: MainAxisSize.max, children: _children, )); } I then

程序员如何在30岁后越老越吃香?

混江龙づ霸主 提交于 2021-02-20 12:55:15
程序员是一门靠手艺吃饭的工作,最根本的就是技术能力。从初级到高级,从高级到资深,从资深到架构,就像爬楼一样,站的越高需要看到的视野越开阔。30岁前程序员靠体力,30岁后需要靠脑力,需要靠技术视野打开更广阔的职业生涯。程序员们很苦恼,技术层出不穷让人应接不暇,需要不停学习新的技术避免被淘汰,但是仅仅靠学习新技术就好了吗?所谓的技术视野到底是什么,又如何去提升呢? 1 驱动力 首先需要明白做一件事情一定需要一定的驱动力,那么对于提升技术视野的驱动力在哪呢? 兴趣 兴趣爱好是最好的老师,所以兴趣是第一驱动力。如果你对一门技术充满好奇心,你一定想尽办法弄清楚它的原理,并且迫不及待的进行实践。 谷歌有一个20%的计划,规定员工可以拿出20%的时间从事自己兴趣爱好的事情。于是从中诞生了Gmail, Google Glass等创新性的产品。这些产品的诞生第一原动力就是兴趣爱好! 态度与使命 兴趣不等于工作,日常工作往往枯燥乏味让人提不起劲,这时候靠什么支撑,可以多想想自己的态度和使命。每一件事情做完后可以反思,是否用了100%的能力,不要留有遗憾。做事也需要有使命感,比如阿里的"让天下没有难做的生意"、腾讯的"科技向善"、美团的"Eat better, live better",每一家伟大公司都有一个伟大使命,让你的日常工作和公司使命关联起来,瞬间是不是觉得自己在从事一项拯救地球的事业。
