In recent times, app developers use software development kits (SDK) to create websites and apps with modern features. SDKs provide a wide array of tools, libraries, sample codes, user guides, and documentation. Flutter is one of such platforms that developers use to create apps. Keep on reading to learn more about the useful features and functions of Flutter.

Introducing Flutter

Flutter presently supports only the Dart programing language. Some of its features include hot reload technology that enhances the development cycle. In essence, the changes made to the code of the flutter apps reflects in the app interface instantly. Flutter apps enjoy a better performance on mobile because of the ahead-of-time (AOT) technology to compile across both Android and iOS platforms.

Another excellent feature of Flutter is the low-level rendering function powered by a C++ based engine and the Google Skia library. It works seamlessly with Android and iOS SDKs. The Flutter Engine is crucial to the Flutter platform as it serves as a portable runtime for hosting Flutter apps. It is also the engine that powers vital app functions such as file and network I/O, accessibility support, compile toolchain, animation, plugin architecture, core libraries, graphics, and many more.

The Benefits of Flutter

  • Open-source: The open-source nature of Flutter makes it appealing to both businesses and developers alike. The platform also has extensive documentation and a vibrant community of developers that can offer support and help when the need arises. Flutter and Dart are downloadable online for free.
  • Improved Compatibility: Developers can use Flutter widgets, which works seamlessly with different operating systems. So, compatibility problem is no longer an issue. Moreover, flutter widgets can be customized by the developer. So, there is no need to waste time testing Flutter apps on old versions of operating systems.
  • Cross-platform development: Flutter is a resource-efficient tool for developing apps for multiple platforms. A single code can be used to deploy both Android and iOS apps. In essence, developers can save lots of time and resources by taking advantage of the cross-platform development capabilities of Flutter.

What is a Backend as a Service?

Developers on BaaS platform use APIs and SDKs to connect apps to the cloud backend. In essence, BaaS development model requires the building of the API before developing the Android or iOS App. It is considered as a stress-free development model since the service provider takes care of the infrastructure and backend hassles.

The Benefits of Backend as a Service

  • Fast Development: BaaS development model allows developers to create apps faster than ever before. Thanks to the APIs and other development tools available on BaaS platforms.
  • Simplicity: BaaS platform is a stress-free model for app development because the service provider takes care of infrastructure and backend services.
  • Versatility: Backend as a Service development model makes it easy to create web apps, mobile apps, and deploy APIs on a single platform.
