How Flutter works
The widget as a fundamental component
A Flutter app is basically a widget, which in turn can consist of numerous other widgets. A widget itself contains not only its representation layer but also the logic that defines its behaviour. The basic widgets, such as buttons or input elements, are provided by Flutter itself.
A unique rendering technique
Unlike other frameworks, Flutter renders its user interfaces entirely on its own engine, which allows for better performance and faster development.
To do this, Flutter basically occupies the area of the screen when the app is started and then draws each widget with its individual state on this canvas. This process is repeated every time the state of a widget changes, so that user actions are responded to immediately.
Using your own engine has many advantages:
Flutter uses the GPU to render content, which enables a fast and responsive user interface.
Better performance on mobile devices
Flutter's engine is specially optimized for mobile devices so that apps also run optimally on older devices.
Independence from platforms
By using its own engine, it is less prone to platform- and operating system-specific problems.
Main features of Flutter
Variety of widgets
Flutter offers a variety of ready-made widgets to quickly and easily create a user-friendly interface.
Flutter uses its own engine, which ultimately leads to better performance, faster development and fewer errors.
Hot Reload allows developers to see their changes in real time without having to recompile all the code. This significantly speeds up the development process.
Flutter offers inherently simple approaches to implementing impressive animations in apps.
Integrated debugging tools
Flutter offers a range of built-in debugging tools that make it quick and easy to identify and fix problems.
And many more functions..
to develop modern applications.
Advantages and disadvantages of Flutter
No technology is perfect in itself, but is better or worse suited for certain use cases. For this reason, we also highlight the advantages and disadvantages of the Flutter framework in this section.
In summary, Flutter provides a modern and efficient solution for mobile app development that offers unique benefits such as a modular and structured architecture, an efficient language, and hot reload. Although there are some limitations, such as a smaller community and limited support for third-party libraries, we believe that Flutter should be seriously considered for tech-savvy companies looking for a solid app framework or even considering a cross-platform development strategy.
