What is Dart and why should you use it?




Dart is a client-optimized language that was created by Google in 2011. It is designed to offer the most productive programming language for multi-platform development, paired with a flexible execution runtime platform for app frameworks.


Dart is a client-optimized language for fast apps on any platform




Dart has a syntax that is easy to learn and familiar to many developers. It supports both static and dynamic typing, allowing you to write code that is expressive, concise, and robust. It also has a rich set of core libraries that provide essential functionality for common tasks.


Dart can compile to native machine code for mobile, desktop, and backend platforms, or to JavaScript for web platforms. This means that you can write one codebase and run it on multiple devices with high performance and quality.


Dart offers sound null safety, object-oriented programming, and quick and reliable compilers




Dart has a sound type system that ensures that a variable's value always matches its static type. This prevents null errors at runtime and enables better code analysis and optimization. Dart also supports sound null safety , which means that values can't be null unless you explicitly allow them to be.


Dart is an object-oriented programming language that supports single inheritance of classes, mixins, interfaces, generics, abstract classes, and extension methods. It also has features such as records , patterns , and class modifiers that make it easier to work with data structures and immutable objects.


Dart has two compilers that can help you develop and deploy your apps faster. The dartdevc compiler can perform incremental compilation and hot reload , which allow you to see the changes in your code instantly in your running app. The dart2js compiler can produce optimized JavaScript code that runs fast on modern browsers.


Dart is the foundation of Flutter, a popular framework for cross-platform app development




Dart is not only a language but also a platform that powers Flutter , a UI toolkit that lets you build beautiful and native apps for iOS, Android, web, desktop, and more from a single codebase. Flutter uses Dart's features such as hot reload , hot restart , stateful hot reload , and state restoration to deliver a fast and smooth development experience. Flutter also provides a rich set of widgets, animations, and themes that make your app look and feel native on any platform.


Dart and Flutter have a large and active community of developers who contribute to the open source projects and provide support and resources. You can find many tutorials, courses, books, blogs, podcasts, videos, and events that can help you learn and master Dart and Flutter.


What is Dart 6.5 and what are its features?




Dart 6.5 is the latest stable release of the Dart SDK, which was announced on June 9, 2023. It is a major update that introduces several new language features and improvements to the existing ones. Here are some of the highlights of Dart 6.5:


Dart 6.5 introduces records, patterns, and class modifiers




Records are a new kind of data structure that are similar to classes but have some differences. Records are immutable, meaning that their fields cannot be changed after they are created. Records also have structural equality, meaning that two records are equal if they have the same fields with the same values. Records can be used to represent simple data objects that do not need any behavior or logic.


Patterns are a new way of matching values against different shapes or forms. Patterns can be used with the match expression , which is similar to a switch statement but more powerful and expressive. Patterns can match values based on their types, fields, constructors, literals, or custom conditions. Patterns can also extract values from the matched value and bind them to variables for further use.


Class modifiers are a new feature that allow you to add additional information or constraints to your classes. Class modifiers can be used to mark a class as abstract , sealed , or final . Abstract classes are classes that cannot be instantiated and must be extended by other classes. Sealed classes are classes that cannot be extended by other classes outside their library. Final classes are classes that cannot be extended by any other class.


Dart 6.5 also improves performance, tooling, and web support




Dart 6.5 also brings some improvements to the performance of the Dart VM and the dart2js compiler. The Dart VM has improved its garbage collection algorithm, which reduces memory usage and pauses. The dart2js compiler has improved its code generation and optimization, which reduces code size and increases speed.


Dart 6.5 also enhances the tooling support for Dart developers. The dart analyze command has been improved to provide more accurate and helpful feedback on your code quality and potential errors. The dart dev tools have been updated to support records and patterns, as well as provide better debugging and testing features.


Dart 6.5 also improves the web support for Dart developers. The dart:html library has been updated to support more HTML elements and attributes, as well as web components and custom elements . The dart:web_audio library has been added to support web audio API , which allows you to create and manipulate audio in your web apps.
