Dart for Flutter: The Flutter framework recommended the most nowadays for mobile apps and Flutter is purely based on Dart. So the mobile developers have to learn Dart, in order to get started with Flutter. The people nowadays use web, Android, iOS and many more and Flutter enables one to shift to these platforms from a single code base. How is this made possible? It is actually done using a programming language that fits to all these platforms, and Dart really does a great work in this role. It supports multi-platform environment as well as offers a speedy development experience.
The problems that are usually faced while building mobile apps are slow compile and debug cycles. But Dart uses hot-reload where the Dart VM can apply changes to the processes(running or live program). The function hot reload actually works by injecting the updated source code files and libraries into the running Dart VM. Is this synonymous to hot restart? No, hot restart is slower compared to reload. It actually works by destroying or rebuilding the state value and then setting it to default.
Dart was developed by Google as an internal programming language to build web,server and mobile applications. And when Flutter was released, the fame of Dart rose much more.
Dart is also having a package manager called Pub. It contains reusable libraries packages for Flutter, Angular Dart, and general Dart programs. It also allows us to share the packages to everyone.
Even after learning and comparing these two competing languages, its really difficult to find the dominating one in the field of cross-platform mobile application development. But as Flutter is growing day by day by adding fresh features to it, Dart is sure to have taken off very steadily. Still its unpredictable about who will grab the market in the near future.
