It’s time to talk about fresh but promising technologies, such as Dart and Flutter. While almost everyone is already aware of Golang, Google’s Flutter toolkit is another progressive framework that is now widely used among front-end developers. Flutter 1.0 was released on December 4th, 2018 at Flutter Live.
Dart & Flutter: Why They Deserve Attention
Flutter is a free, open-source Software Development Kit (SDK) for mobile application development. With Flutter framework, programmers can build outstanding native applications for iOS and Android systems from a single codebase.
Flutter applications are written on Dart — a programming language, created by Google. Dart is scalable and cohesive, which makes it a perfect solution for application development, especially in tandem with Flutter. But why have the creators of Flutter chosen exactly Dart among such a big choice of programming languages?
Dart’s core library is so comprehensive that it covers almost all the needs a programmer can only have. Nick Manning states in his article on Hacker Noon that:
“There is less availability of third-party libraries written in Dart. Yet these are not deal breakers, at least in my experience. 95% of the features I’ve needed to use were there and available, just one exception was, say, some third-party integration with a popular analytics tool, but nothing that a simple HTTP wrapper couldn’t take care of.”
Dart — a perfect choice for dynamic applications
Dart is easy to learn because Google aims to create their products with a focus on expressiveness, cohesiveness, and agility. For some developers, Dart is similar to Ruby, while others find the resemblance to Java. In all cases, Dart is extremely approachable, which makes it possible to learn it in a couple of days (as well as Google’s Flutter toolkit) given that a programmer has coding experience with either with dynamic or static languages.
App Store demands applications to be dynamic and Dart perfectly deals with the task using Ahead-Of-Time (AOT) compilation strategy. It is also capable of using a Just-In-Time compilation in the course of the development process. Stateful hot reload (necessarily in debug mode) gives a programmer the ability to make changes and see the result on the emulator in under a second. However, deploying to mobile, you simply don’t want or can’t use JIT compilation. Hence, AOT compilation means there are no warm-up phases, and the code converts into the demanded form before it’s actually time to do so. Thus, AOT compilation allows the applications written on Dart to launch faster, take up less space, and save battery life.
