How is flutter more useful
As you know nowadays many apps need to run on different operating systems like Android, IOS and the Web that’s why to google introduced Flutter.
Flutter is capable to create a beautiful native app in a single code that can be run on different platforms and it does not compromise with quality, speed, and performance.
Now developers can run a single application on multiple platforms like Android, IOS, Web as well as Desktop but the developer can make this type of app using only Code magic editor.
How it works
Flutter renders your application rather than letting the platform do so. This means your application will responsive and much faster and also can run any platform.
Flutter is also capable to build a native application also means you can make an application that runs only on a specific platform using PlatformChannel. Flutter default uses Dart language for development but if you want to build an application that runs on Android or IOS so you have to need to use Kotlin or Swift respectively.
Dart is also a programming language announced by google in July 2014 but it flopped so now google used it with Flutter. Dart language using JIT (just in time) compiler so it is able to compile a code within a few seconds it also provides how-to reload functionality in a flutter.

Internally flutter consist of a framework built with Dart and rendering engine built in c++, because everything top region is Dart so that you can change all level of the framework.
As you know in flutter everything is a widget like a view in Android. A widget can define the structural elements, layouts, etc.
