An Overview of DART - Programming Language

Dart is a programming language which was developed by Google and Used to build mobile apps, web apps, and server.  It is an object-oriented language and has syntax of c language. It supports object-oriented concepts with support for inheritance, interfaces, mixins, abstract classes, generics, static typing. Dart language also run via javascript. It is an easy write development language which suits the modern app development. Meanwhile, iOS app development India capable of offering high-performance implementations. Dart obtain strong support base which holds a lofty of libraries plus tools offer a great many applications. 

Objectives:

Here come the major objectives of Dart which helps in simplifying any programming module. Along with Dart is a rigid platform that’s why it is used to develop real-time applications with the best quality. Dart 2.1 is a new release which has an update of the following things:

• Int to double value inference
• New mixins syntax and support
• Faster tool and small output
• Compile time type checking

Dart is a unique language in providing both a virtual machine (VM) and compilation to both native machine code and JavaScript. This supports the various platforms, for both development and production.

Mobile apps which come under Dart are purely developed by Flutter indeed its an SDK which helps to create mobile apps. Alongside both iOS and Android, apps can be developed by means of Flutter’s single codebase apps tends to be high-performance and high-fidelity as well.

Int to double value inference:

In Dart 2.1 there is a new feature where datatype value inference is included in Dart 2.1 like int automatically evaluated to double. Where Int to double conversion is support by the Dart 2.1. In the previous version of Dart, the conversion of int to double is not possible and it provides warning while compiling the program. Now, int to double conversion is supported.

Compile time type checking:

This checking process in Dart 2.1 is very helpful in the development process where the type is checked while compiling time for example, if we declare a type and been passed with a state. When the passed state is type correct then there won’t be any sort of issue. But,  if the state is mismatched with declare type then a warning is provided to change the respective thing. Where in the previous version of Dart is program is executed and the issue won’t be shown to the development which makes a problem in the development process. Dart 2.1 completely checks the type and analyze the process of work.

Language support for mixins:

Dart 2.1 brings a new syntax for mixins, a new mixin keyword where you can use it to define classes that can only be used as mixins. It supports mixins so that it can extend other classes and which can invoke methods in their superclass.
