FLUTTER – Fringe Benefits Like No Other

Flutter is a project started by Google, which they have been heavily promoting since 2017. The main objective of Flutter is to enable developers to deliver high-performance apps (applications) that feels natural on different platforms. This technology assists app developers in building cross-platform apps faster by using a single programming language.

The core principle of this Flutter is that it includes a modern react-style framework, ready-made widgets, a 2D rendering engine, and development tools. These components operate together to help to design, build, test, and debug apps.

WHY USE FLUTTER:

Flutter is a highly productive, that is with a single codebase developer can develop iOS apps and Android apps. With few codes, developers can do more that is even on a single OS, expressive language, and declarative approach. Experimental changes on codes and reloading with hot reload can be done quickly and fixing crashes and debugging from where the App where it had previously stopped.

With the help of Flutter, we can create beautiful and highly customized user experiences by a rich set of Cupertino (iOS-style) widgets that were built using Flutter's framework. Without restricting OEM (original equipment manufacturer), widgets sets developers can create beautiful, custom, brand-driven designs.

The significant components of Flutter include:

  • Dart platform
  • Flutter engine
  • Foundation library
  • Design-specific widgets

Let us know what exactly these components are:

DART PLATFORM: During the inception of Flutter, programmers analyzed and evaluated many languages and end up choosing DART, due to some fringe benefits it offers to the programming. For a developer, it is an advantage to use DART for a flutter, as DART is Ahead of Time (AOT) that is compiled to fast, predictable, and native code, which allows a developer to customized everything quickly. In addition to that, DART is also Just in Time (JIT) that is compiled to make development fast and accurate, which becomes quick and easy for a developer to develop programs instantly.

FLUTTER ENGINE: Flutter's engine is generally written primarily in C++, it takes core technologies, Skia, a 2D graphics rendering library and DART, a VM for a garbage-collected object-oriented language, and hosts them in a shell. Different platforms have different shells. We also have an embedder API, which allows Flutter's engine to be used as a library. The shells implement platform-specific code, such as communicating with IMEs (on-screen keyboards) and the system's application lifecycle events.

FOUNDATION LIBRARY: The Foundation library, written in DART, provides essential functions and classes which are used to construct apps using Flutter, such as APIs (application program interface) to communicate with the engine.

DESIGN-SPECIFIC WIDGETS: Flutter widgets are built using a modern framework that takes inspiration from React. The main idea is that you make your UI out of widgets. The main trick is to understand and realize that any widgets that are assembled under a single build method are also referred to as a single widget. Complex widgets can be created by combining many simple widgets. The App is the collection of small widgets to make one largest Widget of them all, which is often/frequently called "MYAPP." The flutter framework contains two sets of widgets that conform to specific design languages.

CLOSURE:

Flutter does a great job by providing an excellent framework to build mobile apps (applications) independently. It supposes simplicity in the development process, a rich and relevant user interface for both the Android and iOS platforms, which results in high performance in mobile apps. There will be no predictions or guesses done here, but it could be the distress signal for native mobile app developers that something like Flutter might influence their role in the future.

“Love Flutter or hate Flutter, one cannot ignore it anymore in the future.”
