Why Dart Programming Dart has a declarative and programmable layout that is easy to read and visualize. Hence, Flutter doesn't require a separate declarative layout language like XML. It is easy for Flutter to provide advanced tooling since all the layout in one language and in a central place. Why is Dart better than Java? Dart is a programming language used by flutter, flutter is used to create cross-platform apps (for android & ios). If your plan is to only create apps for android only you should definitely go with java, it will run and look better in almost every way. What is the advantage of Dart? Dart is an interesting programming language with features to facilitate Web, mobile and command line apps. Its major advantages are its stability and ease of learning. In the case of Web applications, the combination with AngularDart makes it a very powerful tool. Four Reasons Dart enforces object-oriented programming Dart compilers are quick and reliable Dart has a clean and type-safe syntax Dart has a strong developer community Dart Programming Features Open Source Dart is an open-source programming language, which means it is freely available. It is developed by Google, approved by the ECMA standard, and comes with a BSD license. Platform Independent Dart supports all primary operating systems such as Windows, Linux, Macintosh, etc. The Dart has its own Virtual Machine which known as Dart VM, that allows us to run the Dart code in every operating system. Concurrency Dart is an asynchronous programming language, which means it supports multithreading using Isolates. The isolates are the independent entities that are related to threads but don't share memory and establish the communication between the processes by the message passing. The message should be serialized to make effective communication. The serialization of the message is done by using a snapshot that is generated by the given object and then transmits to another isolate for desterilizing. Concurrency Flexible Compilation Dart's flexibility in compilation and execution doesn't stop
