2020 flutter_什么是Flutter以及为什么要在2020年学习

2020 flutter

This year, mobile applications continued to become more and more popular. Fortunately there are many programming tools available to developers who want to create them. Among these tools there is Flutter, which has distinguished itself lately.

今年，移动应用程序继续变得越来越流行。幸运的是，有许多编程工具可供想要创建它们的开发人员使用。在这些工具中有Flutter，该工具最近很出众。

什么是颤振？ (What is Flutter?)

Flutter is a free and open-source mobile UI framework created by Google and released in May 2017. In a few words, it allows you to create a native mobile application with only one codebase. This means that you can use one programming language and one codebase to create two different apps (for iOS and Android).

Flutter是Google创建的免费开放源代码移动UI框架，于2017年5月发布。简而言之，它允许您仅使用一个代码库创建本机移动应用程序。这意味着您可以使用一种编程语言和一种代码库来创建两个不同的应用程序(适用于iOS和Android)。

Flutter consists of two important parts:

Flutter由两个重要部分组成：

An SDK (Software Development Kit): A collection of tools that are going to help you develop your applications. This includes tools to compile your code into native machine code (code for iOS and Android).
SDK(软件开发套件)：一系列可帮助您开发应用程序的工具。这包括将您的代码编译为本机代码(iOS和Android的代码)的工具。
A Framework (UI Library based on widgets): A collection of reusable UI elements (buttons, text inputs, sliders, and so on) that you can personalize for your own needs.
框架(基于窗口小部件的UI库)：您可以根据自己的需求进行个性化的可重复使用的UI元素(按钮，文本输入，滑块等)的集合。

To develop with Flutter, you will use a programming language called Dart. The language was created by Google in October 2011, but it has improved a lot over these past years.

要使用Flutter进行开发，您将使用一种称为Dart的编程语言。该语言是Google于2011年10月创建的，但在过去的几年中，它有了很大的改进。

Dart focuses on front-end development, and you can use it to create mobile and web applications.

Dart专注于前端开发，您可以使用它来创建移动和Web应用程序。

If you know a bit of programming, Dart is a typed object programming language. You can compare Dart's syntax to JavaScript.

如果您懂一些编程，那么Dart是一种类型化的对象编程语言。您可以将Dart的语法与JavaScript进行比较。

“Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase.” - Google, flutter.dev

“ Flutter是Google的UI工具包，可通过单个代码库为移动，Web和桌面构建漂亮的，本机编译的应用程序。” -Google ， flutter.dev

为什么要学习Flutter？ (Why you should learn Flutter?)

I selected some of the reasons why I like Flutter and why I want to use it next year. I will give you details and my feedback below.

我选择了一些为什么我喜欢Flutter以及为什么要在明年使用它的原因。我将在下面为您提供详细信息和反馈。

2020 flutter_什么是Flutter以及为什么要在2020年学习 — Companies using Flutter 使用Flutter的公司

易于学习和使用 (Simple to learn and use)

Flutter is a modern framework, and you can feel it! It’s way simpler to create mobile applications with it. If you have used Java, Swift, or React Native, you'll notice how Flutter is different.

Flutter是一个现代框架，您可以感受到它！使用它创建移动应用程序更简单。如果您使用过Java，Swift或React Native，您会注意到Flutter有何不同。

I personally never liked mobile application development before I started using Flutter.

在开始使用Flutter之前，我个人从未喜欢过移动应用程序开发。

What I love about Flutter is that you can create a real native application without a bunch of code.

我喜欢Flutter的地方在于，您无需编写任何代码即可创建真正的本机应用程序。

快速编译：最高生产率 (Quick compilation: maximum productivity)

Thanks to Flutter, you can change your code and see the results in real-time. It’s called Hot-Reload. It only takes a short amount of time after you save to update the application itself.

感谢Flutter，您可以更改代码并实时查看结果。称为热重装。保存后，只需要很短的时间即可更新应用程序本身。

Significant modifications force you to reload the app. But if you do work like design, for example, and change the size of an element, it’s in real-time!

重大修改迫使您重新加载应用程序。但是，例如，如果您确实像设计那样工作，并且更改元素的大小，则它是实时的！

启动MVP的理想选择 (Ideal for startup MVPs)

If you want to show your product to investors as soon as possible, Flutter is a good choice.

如果您想尽快向投资者展示您的产品，Flutter是一个不错的选择。

Here are my top 4 reasons to use it for your MVP:

以下是我将其用于MVP的4大理由：

It’s cheaper to develop a mobile application with Flutter because you don’t need to create and maintain two mobile apps (one for iOS and one for Android).
使用Flutter开发移动应用程序比较便宜，因为您无需创建和维护两个移动应用程序(一个用于iOS，一个用于Android)。
One developer is all you need to create your MVP.
创建MVP只需一名开发人员。
It’s performant – you won't notice the difference between a native application and a Flutter app.
它性能卓越–您不会注意到本机应用程序和Flutter应用程序之间的区别。
It’s beautiful – you can easily use widgets provided by Flutter and personalize it to create a valuable UI for your customers (you can find examples of applications made with Flutter below).
它很漂亮–您可以轻松地使用Flutter提供的小部件并将其个性化，从而为您的客户创建有价值的UI(您可以在下面找到使用Flutter开发的应用程序示例)。

好的文档 (Good documentation)

It’s important for new technology to have good documentation. But it’s not always the case that it has it!

具有良好的文档对于新技术很重要。但是，并非总是如此！

You can learn a lot from Flutter's documentation, and everything is very detailed with easy examples for basic use cases. Each time I’ve had a problem with one of my widgets in my code, I have been able to check the documentation and the answer was there.

您可以从Flutter的文档中学到很多东西，所有内容都非常详细，并提供了一些简单的基本用例示例。每次我的代码中的一个小部件出现问题时，我都可以检查文档并找到答案。

成长中的社区 (A growing community)

Flutter has a robust community, and it’s only the beginning!

Flutter具有强大的社区，这仅仅是开始！

As you may know, I love to share my knowledge and useful content on programming on my website. I need to know I’m working on a technology full of potential with a lot of backers.
