why Flutter uses Dart

One of the most important reasons why programmers love Flutter and prefer it is Dart. During the inception of Flutter, programmers analyzed and evaluated many languages and ended up choosing Dart due to some astonishing reasons and benefits it offers to the programming. Here are some of the reasons why Flutter uses Dart.

For developers, it is an added advantage to use dart for Flutter as Dart is ahead of time (AOT) that is compiled to fast, predictable and native code and it allows developers to use Dart to write all of Flutter. When it comes to customization, it becomes easy for developers to customize everything and that too quickly.

In addition to that, Dart is also Just In Time that is compiled to make development fast and accurate and it becomes quick and easy for developers to develop program instantly.

Also, if developers want to develop animations and transitions, it is very easy and quick with Dart. These animations run at the speed of 60 frames per second. Also, Dart is capable of doing object allocation and garbage collection without any locks and does not need preemptive scheduling and shared memory. Also, when it comes to creating a bridge between realms, it is not needed with Dart as Flutter apps are compiled to native code. The start-up time is also faster and quick.

Flutter uses Dart as Dart allows Flutter to avoid the need for a separate declarative layout language like JSX and XML. The layout of Dart is declarative and programmatic and it makes it easy for developers to read and visualize it very easily and effortlessly. In addition to that, it makes easy for Flutter to provide additional tooling as the layout is in one language and a commonplace.

Most of the Dart features are similar to that of static and dynamic languages and it makes it easy for developers to learn and understand Dart easily and quickly.

If you see closely, not all the features mentioned above are extraordinary and superior, however, when these features are combined, they serve as the best implementer for Flutter. It is not an overstatement to say that Flutter app development will not be as smooth and streamlined without Dart.

Let's discuss some of the additional characteristics of Dart that explains a strong relationship between Flutter and Dart.

Compilation and Execution

If you look at the history of web application development, there were a total of two types of programming languages: static languages and dynamic languages. Static languages in which variables are typed statically such as C and Fortran at compile time. Dynamic languages are ones in which the variable can be changed at run time such as JavaScript. Also, static languages were used to write native machine code that can be run by the hardware whereas dynamic languages were executed by an interpreter and it does not require any machine language code.

With time, things have advanced and become somewhat complicated too. The virtual machines were introduced by the developers that can mimic a hardware machine in software. They are called advanced interpreters and they make it easier for developers to port a language to new and advanced hardware platforms. The input language becomes an intermediate language that is executed on a virtual machine.

Also, the time is now for Just In Time compilers and Ahead of Time compilers that run during the execution of the program and compile it on the fly.

The development cycle is measured by the time between making a change or modification to the program and the time is taken to execute the program to see the result of the change. When it comes to AOT compilation, development cycles go slow. You might find it a limitation for AOT compilation, but the accuracy and the program can be run predictably without pausing for analysis and compilation at runtime. In addition to that, it is quick and easy to execute compiled programs.

On the other hand, when it comes to JIT compilation, it offers much more development cycles, but the execution is slow and jerkier. Also, the starter time for JIT compilers as it has to give some time for analysis and compilation of the program. The main issue is user experience here. Users would abandon the app if it takes more time to execute and load.

How about combining both AOT and JIT? What would be the effects on program execution? Let's discuss.

Compiling and Executing Dart

Dart developers understood this issue before they have started working on Dart Development. Hence, they have done unparalleled work on advanced compilers and virtual machines for dynamic and static languages. The result was awesome. Dart is phenomenally flexible when it comes to compilation and execution.

If you are looking for a language that is excellent at compiling both AOT and JIT, Dart is your answer. The reason why Flutter with dart makes a great pair is the significant advantages Dart brings by being capable of supporting both types of compilation.

During the development, with a fast compiler, JIT compilation is performed and when the app is ready for release and deployment, it is compiled AOT. The two most crucial aspects can be achieved with the help of Dart- superior and rapid development cycles and quick and fast Execution and startup times.

Not just that, Dart can also be compiled into JavaScript and it allows Flutter developers to use the code between mobile apps and web apps. Dart can also be compiled to native code or JavaScript with node.js to be used on a server.

It is a standalone and highly effective virtual machine that uses Dart language as its intermediate language and acts as an interpreter. Also, Dart can be compiled and transpiled into other languages too. It is not just flexible and versatile, but extremely fast too.
