Dart is a client-optimized language for developing fast apps on any platform.Its goal is to offer the most productive programming language formulti-platform development, paired with aflexible execution runtime platform for app frameworks.

Dart is a programming language designed by Lars Bak and Kasper Lund and developed by Google. The programming language is designed for client development such as for the web and mobile apps, and it can also be used to build server and desktop applications.

Dart 2.6 introduced a new extension, dart2native, which extends native compilation to the Linux, macOS, and Windows desktop platforms. Earlier developers could create new tools using only Android or iOS devices. With this extension it also becomes possible to compose a program into self-contained executables. According to company representatives, it's no longer necessary to have the Dart SDK installed, as the self-contained executables can now start running in a few seconds. The new extension is also integrated with the Flutter toolkit, making it possible to use the compiler on small services (for example, backend support).[14][15]

The first compiler to generate JavaScript from Dart code was dartc, but it was deprecated. The second Dart-to-JavaScript compiler was Frog. It was written in Dart, but never implemented the full semantics of the language. The third Dart-to-JavaScript compiler was dart2js. An evolution of earlier compilers, dart2js is written in Dart and intended to implement the full Dart language specification and semantics.

On March 28, 2013, the Dart team posted an update on their blog addressing Dart code compiled to JavaScript with the dart2js compiler,[30] stating that it now runs faster than handwritten JavaScript on Chrome's V8 JavaScript engine for the DeltaBlue benchmark.[31]

The Dart team created DartPad at the start of 2015, to provide an easier way to start using Dart. It is a fully online editor from which users can experiment with Dart application programming interfaces (APIs), and run Dart code. It provides syntax highlighting, code analysis, code completion, documentation, and HTML and CSS editing.[42]

The tutorial assumes that the readers have adequate exposure to object-oriented programming concepts. If you have worked on JavaScript, then it will help you further to grasp the concepts of Dart quickly.

Develop your apps with a programming language specialized for the needs of user-interface creation. Dart provides the language and runtimes that power Flutter apps, but Dart also supports many core developer tasks like formatting, analyzing, and testing code.

Dart is an object-oriented client-optimized programming language used to build mobile and web applications on various platforms. It has easy-to-use applications that can be utilized to work on both the user and server end. Dart employs C-style syntax and is mainly used to create front-end user interfaces for mobile applications.

An object-oriented programming language, Dart uses data as objects instead of treating it as functions or logic. It supports both basic and advanced object-oriented programming concepts like class, interfaces, abstract, and mix-in.

Being a compiled language, Dart allows developers to discover programming errors during the compilation process. Hence, it is considered a type-safe language. On the other hand, Java is an interpreted language and allows developers to find programming errors during the runtime. Therefore, Dart is a more type-safe language in comparison to JavaScript.

Dart is an open-source, general-purpose, object-oriented programming language with C-style syntax developed by Google in 2011. The purpose of Dart programming is to create a frontend user interfaces for the web and mobile apps. It is under active development, compiled to native machine code for building mobile apps, inspired by other programming languages such as Java, JavaScript, C#, and is Strongly Typed. Since Dart is a compiled language so you cannot execute your code directly; instead, the compiler parses it and transfer it into machine code.

It supports most of the common concepts of programming languages like classes, interfaces, functions, unlike other programming languages. Dart language does not support arrays directly. It supports collection, which is used to replicate the data structure such as arrays, generics, and optional typing.

Dart is a Strongly Typed programming language. It means, each value you use in your programming language has a type either string or number and must be known when the code is compiled. Here, we are going to discuss the most common basic data types used in the Dart programming language.

Besides variable, Functions are another core feature of any programming language. Functions are a set of statements that performs a specific task. They are organized into the logical blocks of code that are readable, maintainable, and reusable. The function declaration contains the function name, return type, and parameters. The following example explains the function used in Dart programming.

Comments are the lines of non-executable code. They are one of the main aspects of all programming languages. The purpose of this is to provide information about the project, variable, or an operation. There are three types of comments in Dart programming:

Dart is an object-oriented programming language, which means every value in a Dart is an object. A number is also an object in Dart language. Dart programming supports the concept of OOPs features like objects, classes, interfaces, etc.

Dart is an open-source general-purpose programming language developed by Google. It supports application development in both client and server-side. But it is widely used for the development of android apps, iOS apps, IoT(Internet of Things), and web applications using the Flutter Framework.

In Dart programming, List data type is similar to arrays in other programming languages. List is used to representing a collection of objects. It is an ordered group of objects. The core libraries in Dart are responsible for the existence of the List class, its creation, and manipulation.

In Dart programming, Maps are dictionary-like data types that exist in key-value form (known as lock-key). There is no restriction on the type of data that goes in a map data type. Maps are very flexible and can mutate their size based on the requirements. However, it is important to note that all locks (keys) need to be unique inside a map data type.

Dart is a general-purpose, high-level modern programming language which is originally developed by Google. It is the new programming language which is emerged in 2011, but its stable version was released in June 2017. Dart is not so popular at that time, but It gains popularity when it is used by the Flutter.

Dart is a dynamic, class-based, object-oriented programming language with closure and lexical scope. Syntactically, it is quite similar to Java, C, and JavaScript. If you know any of these programming languages, you can easily learn the Dart programming language.

Dart is an open-source programming language which is widely used to develop the mobile application, modern web-applications, desktop application, and the Internet of Things (IoT) using by Flutter framework. It also supports a few advance concepts such as interfaces, mixins, abstract classes, refield generics, and type interface. It is a compiled language and supports two types of compilation techniques.

You don't need specific knowledge to learn Dart programming language even the absolute beginners can learn it. The syntax of Dart is similar to Java, C#, Java, JavaScript, etc. If you know any of these programming, then you can learn easily and faster.

We have developed this tutorial for beginners and professionals both who want to build a career around web-development or seamlessly learn the precepts of Flutter. There are a lot of topics available that will help you to learn the dart programming language easily.

Google had its first ever release of Flutter 1.0 last December, after having it in beta mode for over 18 months. Dart is the programming language used to code Flutter apps. Dart is another product by Google and released version 2.1, before Flutter, in November. As it is starting out, the Flutter community is not as extensive as ReactNative, Ionic, or Xamarin.

Dart, when used in web applications, is transpiled to JavaScript so it runs on all web browsers. The Dart installation comes with a VM as well to run the .dart files from a command-line interface. The Dart files used in Flutter apps are compiled and packaged into a binary file (.apk or .ipa) and uploaded to app stores.

The entry point of the app is main.dart, found inside the lib folder. This folder also contains all Dart classes (app pages or reusable components). On creation of the app, the main.dart file comes with a simple pre-written code. Before running this code, a device is either connected to the PC, with USB debugging enabled. Afterward, run the command flutter run on the terminal.

The primary objective of this article was not to assert the idea that Dart is going to perish soon. Rather, the core idea was to nudge the readers towards the positive developments related to Dart, and it being implemented in different application areas. The fact that Dart was ranked lower in Tiobe index, than other languages, which have very limited potential for application development like R or Dephi, or which are newer like Swift, in-spite of being backed by Google was represented in the article. But this was shown in order to focus on the recent developments related to Flutter and how dart is changing the way mobile apps are being developed. Also the article mentions Fuchsia, the proposed new OS from Google which might change the entire mobile development domain. These are all the positive factors about Dart, which are also mentioned in the article. In no way does the article claim that Dart is history, rat
