What is Dart & Flutter?

Hey Everyone, I would like to tell you all the astonishing information regarding the Dart language which is one of the most emerging and converting into popular languages in the world. Dart language is a compelling language.

What is Dart?

Dart is a client-optimized programming language for apps on multiple platforms. It is developed by Google and is used to build mobile, desktop, server, and web applications. 

Dart is an open-source language developed in Google with the aim of allowing developers to use an object-oriented language with static type analysis. Since the first stable release in 2011, Dart has changed quite a bit, both in the language itself and in its primary goals. With version 2.0, Dart's type system went from optional to static, and since its arrival, Flutter (we'll explain later) has become the main target of the language.

What makes Dart special?

Unlike many languages, Dart was designed with the goal of making the development process as comfortable and fast as possible for developers. So it comes with a fairly extensive set of built-in tools such as its own package manager, various compilers / trans-piled, a parser, and for-matter. Also, the Dart virtual machine and Just-in-Time build make code changes immediately executable.

Once in production, the code can be compiled in the native language, so no special environment is required to run. In the case of web development, Dart is trans-piled into JavaScript.

As for the syntax, Dart's is very similar to languages like JavaScript, Java, and C ++, so learning Dart by knowing one of these languages is a matter of hours.

In addition, Dart has great support for asynchronous, and working with generators and iter-ables is extremely easy.

Important Usages

1. Compiled as JavaScript
2. Stand-alone
3. Ahead-of-time compiled
4. Native

How to run Dart?

To run the app from the command line, use the Dart VM by running the dart run command in the app's top directory: $ cd cl $ dart run Hello world: 42! If you want to run the app with debugging support, see Dart DevTools.

Where can I use Dart?

Dart is a general-purpose language, and you can use it for almost anything:

• In web applications, using the art library: HTML and the trans-piler to transform the Dart code into JavaScript, or using frameworks like Angular Dart.
• On servers, using the art: HTTP and art: Io libraries. There are also several frameworks that can be used, such as Aqueduct.
• In console applications.
• In mobile applications thanks to Flutter

Advantages and Disadvantages of Dart

• Advantages

Dart has a strong support base with many libraries and tools, which enable very large applications. One of the major objectives of Dart is to simplify programming tasks. It is designed to make common programming tasks simpler.

• Disadvantages

Dart has very limited resources online and it's hard to find solutions to problems. The reason for it is the lack of larger and more cohesive developer communities, which will support you.

Dart Vs Java

JavaScript is an interpreted language, so it might feel lighter and faster. It's actually faster than other compiled languages like Java. However, Dart proved to be much faster when bench-marked against JavaScript.

What is Flutter?

Flutter is a Dart framework for creating cross-platform applications with a single code. Unlike other multi-platform frameworks such as Ionic, the code of a Flutter application is compiled into native code, so the performance achieved is superior to applications based on web views. Also, unlike React Native, Flutter doesn't use native components, instead, it comes with its own components, called widgets, so the same app will look the same on any device, regardless of its operating system or version. Thanks to this, the developer does not have to worry about the design of his application looking bad on older devices.

In addition to mobile applications, Flutter can also make web pages and desktop applications, although support for web pages is in beta, and for desktop applications in technical preview, so whoever wants to use them will have to wait a while longer. to make it stable.

How to run Flutter?

Install the Google USB Driver. Using a USB cable, plug your phone into your computer. If prompted on your device, authorize your computer to access your device. In the terminal, run the flutter devices command to verify that Flutter recognizes your connected Android device.

Does flutter need coding?

Flutter uses the Dart programming language which was introduced by Google in 2011 and is rarely used by developers. Dart syntax is easy to understand for JavaScript or Java developers as it supports most of the object-oriented concepts.

Here are some examples of applications developed with Flutter:

• Google Ads 
• App Tree 
• Reflect 
• in-Lay Coffee 
• SSH Buttons

For those interested in learning more about Dart and Flutter, then there is a list of various resources that may be helpful:

• Dart webpage: where you can find all the language documentation and various tutorials. In particular, the Language Tour It is very useful to see a brief introduction to the syntax of the language.

• Dartpad: This allows you to experiment with the language from the browser without having to install anything (you can also write Flutter applications).

• Webpage of the packets repository: where you can find all the community packages.

• Medium pages of Dart and Flutter: with many articles that can be of help.

• Flutter's webpage: where is the documentation of the framework, and how to start using it.

• Flutter's Youtube Channel: with a lot of videos that can be useful. In particular, the video series of Widget of the Week, a series of short videos of a couple of minutes each one explaining a widget, quite useful if you are starting and you are not very clear what widgets exist and how you can use them, and the series Flutter in Focus, with longer videos explaining key concepts from both Dart and Flutter.

Advantages and Disadvantages of Flutter

• Advantages

1. Own Rendering Engine
2. Reduced Code Development Time
3. Increased Time-to-Market Speed
4. Same Ul and Business Logic in All Platforms

• Disadvantages

1. Flutter is still an immature fame-work.
2. Flutter apps are quite large and "heavy" to start with.
3. Flutter is still an immature framework.
4. Flutter is still an immature framework.

Flutter Vs React Native

Flutter is said to be a strong contender to React Native. For now, though, React Native is more mature and stable - not to mention that it takes advantage of the most popular Programming language, JavaScript, and already has a large community of users and supporters behind it.
