This article mainly shows you "why use Flutter", the content is simple and easy to understand, the organization is clear, I hope to help you solve doubts, let Xiaobian lead you to study and learn "why use Flutter" this article.

1. Flutter overcomes traditional cross-platform limitations

Creating a true cross-platform approach has long been a chore for technical consultants, who are tired of making multiple versions of the same product. However, in reality, the user experience of cross-platform apps often lags behind native apps because you often need to compile JavaScript on the fly to build the UI experience.

With Flutter, you not only have the advantage of "write once," but you can also create a high-performance "native" experience because Flutter applications are compiled in advance into machine-executable binaries. It overcomes some common problems with other cross-platform approaches.

2. Developer productivity increased tenfold

This productivity boost comes from Flutter's "hot overload"(so-called "stateful hot overload" and "hot restart"). This way, developers can see the changes they make to the app state in less than a second; and change the app's structure in less than 10s.

There's no need to start another Gradle builder--you can view your changes after saving them. For developers, this is usually easy to master-there is little wait time when using "hot reload," because by default it changes in real time every time it saves.

However, the advantage is crucial. Flutter typically reduces development time by 30-40%, because in Android development Gradle needs to be rebuilt after each modification, which slows down Android developers.

3. Only one code is needed at the front and back

Unlike Android programming, where the front-end ( Views ) has separate files that are referenced by the back-end ( Java ), flutter uses a single language ( Dart ) to do both jobs and uses a responsive framework.

Dart borrows many popular features from other languages, but it doesn't feel strange because it's similar to Java or any other language. Dart is built with ease of use for developers in mind, making many common tasks easier. You can learn more about Dart here: Dart Language Tours.

4. It's a powerful out-of-the-box design experience.

Thanks to the Flutter team's aggressive adaptation of the Material design specification, it's easy for developers to create powerful UI experiences. It can help you generate a smoothness that you normally only experience in native apps, because Flutter's distribution is built to be a native app.

Flutter's widgets also implement iOS's human interface design specifications, allowing you to get that native "experience" on iPhone and iPad.

5. There's a huge open-source software library

There are plenty of open source packages available to help you create applications faster and easier, and there are many packages available today that make many complex tasks easier.

Flutter is actively growing, even though the open source library is not mature enough, thanks to the positive contributions of developers who continue to join.

6. Close integration with Firebase

Firebase provides out-of-the-box support for cloud storage, cloud capabilities, real-time databases, hosting, authentication and more. Your infrastructure can be serverless, redundant and scalable. This means you don't have to spend a lot of time and resources building the backend.

It can also be used directly with a tool to automate your development and release processes to facilitate continuous delivery (e.g. Fastlane). Therefore, you don't have to provide dedicated DevOps support in your team.

7. Flutter is supported by numerous IDEs

When programming with Flutter, you can choose from a number of integrated development environments. At first I used Android Studio, but then I watched Flutter Live using VS Code. This puzzled me because I found that many Flutter developers were using Visual Studio Code. When I tried it, I understood why so many people liked it. VS Code is lighter and faster than Android Studio and IntelliJ, and has most of the features of both. Personally, I've moved to VS Code, but there are many other IDEs available that you can use to get Flutter started without switching.

8. UI compliance-everything is a widget

In flutter, everything is a widget, such as Appbar, Drawer, Snackbar, Scaffold, etc. Developers can easily wrap a widget inside another widget to achieve some effect, such as wrapping a widget inside a Center widget to center it.

This is all to ensure that your users have the same user experience regardless of what platform they are running your software on. You should also read the following flutter documentation: Everything's a widget

9. Different themes for Android/iOS

Assigning the right theme based on the user's platform is as simple as checking the platform the user is running on with a ternary if; allowing the UI to decide which UI components to use at runtime.

Below is an example code that checks the currently running platform and, if it's iOS, returns a theme with purple as the dominant hue.

return new MaterialApp( // default theme here theme: new ThemeData(), builder: (context, child) { final defaultTheme = Theme.of(context); if (defaultTheme.platform == TargetPlatform.iOS) { return new Theme( data: defaultTheme.copyWith( primaryColor: Colors.purple ), child: child, ); } return child; } );

10. Continuous integration with Code Magic.

Code magic is an open source tool used in Flutter Live on December 4, 2018. Code magic is easy to learn and completely free! It is a highly sophisticated CI tool optimized specifically for Flutter. Code magic makes the build process seamless.

11. 2Dimensions makes animation easier

I *** tried Flutter + Flare--Bouncy

Also an amazing online tool launched during Flutter live 2018 that makes it easy to create great UI or animations. It bridges the gap between UI designers and developers, reducing the time required to apply UI or animation-related changes.

Flare's learning curve is shallow, and I was amazed at how easy it was to create animations after using it! You can see the app working here, and I even added a reflection to the ball to give it a more realistic look.

12. Flutter running on desktop and Web

The Flutter team now has a prototype Flutter app that works in a web browser, which surprises everyone. In Flutter Live, the previously top-secret project "Hummingbird" was revealed to the world. Soon, you'll be able to easily create apps for mobile, desktop, and web using the same code.

13. Ongoing support from Flutter team and Flutter community

I have been working with Flutter for the past three weeks and have noticed a lot of support and encouragement from the Flutter team and community; especially Scott Stoll , Nilay Yener and Simon Lightfoot (to name a few). Every Wednesday, many of the more well-known names in the Flutter community can be seen on Zoom at #HumpDayQandA, where you can get help about Flutter from real people in real time. Even if you don't have any questions, it's a good place to be because you can learn a lot from their answers to people's questions.

This is a photo of me participating in #HumpDayQandA. Twitter from Flutter Egypt founder and Google developer Amed Abu Eldahab.

The value of using Flutter is clear and attractive because it alleviates many of the difficulties startups face when trying to release products to multiple platforms; especially when dealing with bringing software products to market within limited time and budget.

That's all for "Why Flutter", thanks for reading! I believe that everyone has a certain understanding, hope to share the content to help everyone, if you still want to learn more knowledge, welcome to pay attention to the industry information channel!
