Why Choose Flutter?

Dart Simplifies Development

Flutter app developers simply love using the object-oriented programming language, Dart, because it’s AOT (Ahead of Time) compiled to native code that makes Flutter blazing-fast. This apart, Dart helps in creating smooth animations at 60fps. Moreover, its declarative layout is easy to read which eliminates the need for a separate declarative layout language. In essence, Dart in Flutter simplifies and eases the development process significantly.

High Performance

Ideal for building complex designs, Flutter is an SDK that facilitates secure and high-performing iOS and Android app development from a shared code structure. The Dart programming language in Flutter helps developers use Just-in-Time compilation for enhanced development workflow. In fact, the availability of extensive Dart libraries and features allows developers to create high-performing native apps for various platforms.

Hot Reload

Flutter’s hot reload is, by far, one of the most lauded features that allow easy and smooth app development. It helps in injecting the source code files directly into the Dart Virtual Machine. After the VM updates classes with the new functions and fields, the framework instantly rebuilds the widget tree, thereby, enabling developers to view the changes instantly. This helps the developers quickly view the changes in the code files without the need of any restart.

Super-fast App Designs

With Flutter, developers can design apps quickly and launch them fast. Flutter offers an extensive library of reusable UI building blocks, utility packages, and functions that aid in the quick designing process. Adding tools, building UIs and removing bugs is easy and hassle-free in Flutter, thanks to its hot reload feature. Developers need not micro-optimize with complex profiling tools when using Flutter. This helps in reducing the app design and development time significantly.

Customizable Widgets

Flutter is a favorite among the developers because it comes with a customizable and rich kit of widgets for iOS and Android. Flutter developers enjoy huge flexibility in using custom widgets such as buttons, texts, checkboxes, images, layout columns, padding, styles, gesture detectors, etc. This flexibility helps them create refined, smooth and top-notch UIs with Flutter.

Expressive and Beautiful UI

Flutter’s fully-layered architecture helps developers control every pixel on the screen without letting the quality of graphics, texts or videos, get negatively affected. This open-source UI software development kit enables developers to build awesome interfaces that offer pixel-perfect user experiences on both Android and iOS.
