This hiring guide explores how to identify the Dart developers who are best suited to handle your company’s particular business requirements. You will also find tips for writing effective job posts and navigating the interview and assessment processes.
是什么属性将优秀的Dart开发者与其他开发者区分开来?
A quality Dart developer uses their hard and soft skills to deliver first-class applications that not only fulfill business objectives, 但也要超越客户的期望.
Using Dart, 程序员可以交付可伸缩的产品, 可靠且易于维护的高性能应用程序. 一个高质量的Dart开发人员:
是否熟悉Dart的高级功能. Dart的异步代码和并发特性, for example, 提高应用程序的响应能力.
将Dart应用程序与其他平台或系统集成. A developer’s familiarity with other relevant technologies—such as Flutter or Angular—is crucial for a broader development project.
The quality Dart developer knows that Dart is unusual in its ability to compile to multiple CPU targets, 如ARM和x64机器码的移动设备, web浏览器的JavaScript, 和自包含的Windows可执行文件, macOS, and Linux. 这意味着对于一款多平台应用来说, developers can work from a single codebase instead of one per platform—a highly cost-effective way to develop an app. It also means that JavaScript 技术技能并不是对Dart开发人员的硬性要求. 熟悉JavaScript有助于调试Dart代码和JavaScript代码之间的交互, 但Dart的内置工具在处理此类极端情况时仍在不断改进.
在雇用Dart开发人员为您的组织工作之前, 考虑候选人的技术专长和经验, capacity for teamwork, 了解贵公司的特殊需求和项目要求.
Junior, mid-level, and senior talent are the standard classifications for varying degrees of competence and experience in development:
Junior
Performs simple, repetitive tasks based on existing code and patterns but will need resources and guidance to create wholly new features in a maintainable way.
Consider the specifics of the job so that you tailor the job post to resonate with the ideal candidates for you. 此外，要考虑项目的独特需求和规格、预算和时间表. 然后，针对您的Dart开发人员确定适当的技术专业水平.
If, on the other hand, 比如，这个项目更加复杂, 修改您的库存跟踪器，以包括一个实时跟踪系统, 电子商务平台, and a financial information viewer—you will need a senior developer or perhaps a team of senior developers.
对于范围介于这些示例之间的项目, 考虑您是否需要一个或多个开发人员, 以及执行工作所需的专业知识水平. Generally speaking, the more features, 工作越复杂，对开发人员的技术要求就越高。.
Asking the right questions during interviews with qualified candidates for your Dart developer will allow you to assess whether they are suited to the position. 以下是一些你可能会问的问题:
与其他编程语言相比，Dart的优势是什么?
Dart’s ability to produce quick and effective web and mobile applications gives it an edge over other languages. Dart是一种开源的、用户友好的、面向对象的语言. Moreover, 因为Dart会编译成JavaScript, 它是创建可扩展的灵活选项, 跨平台解决方案. Dart既适合前端开发，也适合后端开发. The Dart developer community is active in creating fresh libraries and productivity-enhancing technologies to complement and expand its ecosystem.
Dart语言中的数据类型是什么?
In Dart, 有几种内置数据类型, 包括数字(整数和双精度), strings, Booleans, lists, sets, and maps. Dart还通过枚举和类支持更高级的类型，如泛型和用户定义类型. 数字可用于算术运算，而字符串保存文本. 布尔值用于表示真/假值. Lists, sets, 和映射用于表示数据集合:列表保存有序的项目集合, 集合保存唯一项的无序集合, 映射保存键值对. 枚举用于定义一组固定的常数值, 而类提供了一种定义自定义类型并在其中封装数据和行为的方法.
如何对Dart代码进行故障排除和调试?
应系统地进行故障排除和调试. Sometimes a quick look at the code or a few print statements will help determine the source of the issue. If not, 像Dart DevTools套件这样的工具可以帮助隔离问题并确定潜在的解决方案. It’s important to document any findings and changes made to the code to ensure transparency and facilitate collaboration with team members.
Finally, 最好利用达特的小队, component, and end-to-end testing utilities to test a solution thoroughly while ensuring it doesn’t cause new issues or resurface old bugs.
Dart中的Streams是什么?
Dart中的流是可以异步处理的事件集合, 当它们发生时，一次一个. 流用于寻址异步数据，例如来自外部源的数据. 而不是等待所有数据到达后再进行处理, 流允许开发人员在数据进入时处理和更改数据. Streams are a feature of Dart’s standard library and are widely used for handling data in real time (e.g.(在聊天程序、新闻提要或股票行情中).
Dart发布的补充软件包有哪些?
Dart包含一个庞大的附加包库，用于扩展该语言的功能. 其中比较受欢迎的选择是 http，一个帮助发送HTTP请求的包. The rxdart 包用于响应式编程. The intl 包支持本地化和国际化，而 shared_preferences 包维护持久的键值对.
为什么null安全在Dart中很重要?
2023年5月发布的第3部 零安全是硬性要求; as such, from a project standpoint, it’s important to know how null safety 工作原理以及如何将代码迁移到null安全以保持工具的最新状态. 就日常编码而言, 空安全性消除了空指针异常和某些其他运行时错误的可能性. Also, null safety carries performance benefits by enabling new classes of automatic optimizations of Dart code.
为什么公司会雇佣Dart开发者?
Dart是构建web、移动和服务器应用程序的流行选择. It is particularly well suited for developing high-performance cross-platform mobile apps using Flutter, Google’s UI toolkit. Companies hire Dart developers to enhance their offerings to the user community and to maintain and fix existing Dart applications.
Dart is a strong and adaptable language that a developer can use to create top-notch apps across a wide range of platforms. 曾经有一段时间，公司必须为每个平台聘请不同的开发人员.g.维护独立的iOS和Android代码库). But today, 雇佣一名Dart开发人员来开发一个, 统一的代码库将为公司节省相当大的成本.
