Here is an example of a traditional object instantiation, using the new keyword: final buffer = new StringBuffer() Like most OOP languages, Dart supports the keyword new for creating instances of classes. The code for this article was tested with Dart 2.8.4 and Flutter 1.17.5. There is more than one way to do almost anything, but what are the best practices in Dart? Here, we'll explore a few for class design and object instantiation.
It's not a dogmatic OO language, like Java, which requires you to define everything within classes, so it's important to know when to keep code outside of classes as well.ĭart has some conventions and special syntax to be aware of when designing classes and instantiating objects of those classes.
Even literals are objects, allowing you to write code like 5.isOdd, which will resolve to true. The Dart language has great support for functional programming, but it's also a pure object-oriented (OO) language with single inheritance and mixin support.
