Dart Course And Certification

What is Dart?

Dart is a client-optimized software programming language that is used for building apps on multiple devices. It is built and managed by Google and is used to build desktop, mobile backend, and web applications. Dart is an object-oriented, garbage-collected, class defined, language using a C-style syntax that optionally trans-compiles optionally into JavaScript. It has support for various interfaces, abstract classes, mixins, reified generics, static typing, and a sound type system.

Dart was unveiled at the GOTO conference in Aarhus, Denmark, on October 10, 2011. The Dart project was founded by Kasper Lund and Lars Bak. Dart 1.0 was released on the 14th of November 2013. In August 2018, Dart 2.0 was released, with various changes and additions to the language including a sound type system.

Recently the release of Dart 2.6 is followed by a new extension known as dart2native. The feature further extends native compilation of Dart programs to macOS, Linux and Windows desktop platforms. Developers before we're able to develop new tools only by using Android or iOS devices. Furthermore, with the inclusion of this extension, it becomes possible to convert a Dart program into self-contained executables with no external dependencies.

Why Dart?

1. Dart is very stable and it can be used to build production-quality real-time applications. It is an object-oriented programming language with support for inheritance, interfaces and optional typing features.

2. Dart language simplifies tasks. It is designed to make common programming tasks simpler.

3. Dart has a strong support base with many libraries and tools, which enable very large applications.

4. The code can be trans-compiled into JavaScript using source-to-source compilation. This is done with the help of the dart2js compiler. As it can be converted to JavaScript, all major browsers support it.

5. The Dart SDK includes a virtual machine called Dart VM. This mode is for standalone execution. The Dart code can be executed in a command-line interface mode. 

6. The Dart code can be executed in another mode through the Dartium browser. This is a customized Chromium Web browser that includes the Dart VM, this browser has direct support for Dart code, and doesn’t need to be converted into JavaScript.

7. Dart can also be executed in AOT mode. AOT stands for Ahead-Of-Time compilation. In this mode, the Dart code can be directly converted into native machine code.

Features of Dart

There are lots of features of Dart and some of them are:

1. Keywords: As with other software development languages, Dart has almost all the regular keywords. In dart, you don't have protected, public, and private keywords in Dart. Instead of, just using an underscore (_) before an identifier to make it private to its library scope.

2. Variables: It is very helpful to think of variables in Dart as containers that hold data and information. Their singular aim is to label and store data in memory. This data can then be utilized throughout your library.

3. Built-in Types: There are various built-in data types which are supported by Dart and some of them are Number,
Strings, Booleans, Lists, Maps, Runes, Symbols.

4. Functions: a function is a named section of a program that carries out a specific task. Dart makes a distinction between a function, that returns a value, and a procedure, which then carries out some operation but does not return a value.

Benefits of Dart

Below are some of the benefits of Dart:

1. Optional static types: Dart allows the use of static data types to be optional. The choice of using classes and static type annotations all fall on the developer.

2. Innocent until proven guilty: Dart tries very well to reduce the situations that result in a compile-time error. Many conditions in Dart are simply warnings, they don't stop the program from running. The developer does not need to first ensure that the entire program is correct before just trying out a section of the code.

3. Lexical scope: Lexical scope in dart is an awesome feature, it lets the visibility of variables, to be defined by the program structure. This takes down a class of puzzlers that are present in traditional web development. there is no need to re-bind functions to keep them to what you think or expect.

4. Top-level functions: In Dart, you can define your program functions at the top level, outside of any class definition. This allows the library organization to have a more natural look and feel.

5. Classes have implicit interfaces: The elimination of explicit type interfaces completely simplifies the language. there is no more need to define IDuck everywhere, all you need require is a class Duck. this is because every class has an implicit type interface, you can define a MockDuck that implements Duck.
