However, Google's launch of the Flutter SDK, which is designed specifically to help developers create natively compiled apps, has arguably reinforced Dart's significance as a language worth learning. Since then, a survey conducted by Stack Overflow identified Flutter as one of 2020's most popular development frameworks. It's foreseeable that the recent push by enterprise-level organizations to build Android and iOS mobile apps may fuel an increased interest in Dart.
Let's take a look at some of the specific strengths of Dart that developers may find attractive enough to add to their coding repertoire.
Dart enforces object-oriented programming
As an object-oriented programming language, Dart designates every application component value as an object. It emphasizes single inheritance of classes, and boasts a syntax similar to other object-oriented languages like Swift and Objective-C.
In general, object-oriented interfaces are used to turn one or more application components into reusable objects, which allows for more advanced coding projects and application service isolation. These objects and the interfaces that generate them are a crucial part of introducing abstraction into an architecture, and also allow for multiple inheritance, where a single object can inherit characteristics and features from more than one parent object.
Dart compilers are quick and reliable
Static typing ensures that once a type is declared, it can't be changed. Thanks to static typing, a Dart compiler can examine the intended applications tasks and alert developers of any errors before the code actually runs. The Dart Development Compiler (dartdevc), in tandem with the Dart webdev CLI, can also spin up a dedicated development server for testing builds and debugging code.
Dart offers ahead-of-time compilations, which automatically compiles code into a format that a native machine can easily read, and allows an application to natively execute binary files. By compiling code during the build process, programmers can also achieve faster UI rendering in browsers. Finally, for applications that run concurrent processes, Dart makes efforts to ensure reliability by reserving private chunks of memory called isolates that can simultaneously execute multiple computations.
Dart has a clean and type-safe syntax
Dart's syntax likely won't impose a tough learning curve for programmers who have experience with Java, as well as those comfortable with .NET languages like C++ and C#. The language allows coders to customize variable names, improve the readability of project code and minimize the need for in-line comments. Development teams also have flexibility to customize the visual structure of their code, including the use of spaces, tabs and line breaks.
Dart has a strong developer community
To help those both new and experienced in the language, developers in the Dart community share packages using a public package repository, which includes libraries for databases, routing and functions. For example, Kiwi is a handy dependency injection container package that stores instances and factories that developers can apply custom names to (note that Kiwi only works with Dart 2.0 or later versions of the language).
