Flutter architecture and libraries

In this blog, we are going to have an overview of Flutter architecture and its libraries. Similarly, we will also have a look on its basic principles and notations that build its design. Everyone knows that flutter is a cross platform UI toolkit.

The Flutter Framework has several segments:

Flutter Architecture and its libraries
  • Layer model: It’s a basic part from which flutter is build.
  • Reactive user interfaces: A basic notation for Flutter UI development.
  • Widgets: They are the primary building blocks of flutter UI.
  • Rendering process: It is a process where the flutter UI turns into pixels.
  • Platform embedders: This lets the code run the flutter apps on mobile as well as on desktop operating systems.
  • Integrating Flutter with other code: Provides information about the several approach available to Flutter apps.
  • Support for the web: Finishing with the remark about the property of flutter within the browser environment.

The Flutter architecture has three parts:

Flutter Engine:

At the fundamental level of flutter is Flutter Engine, it is a lightweight runtime for high quality mobile apps development and it is certainly based on the C++ programming language. Above all Flutter Engine is responsible for converting mixed scenes whenever a new frame is to be loaded. It creates Flutter basic libraries which holds animation, graphics, file and network input/output, plugin architecture, accessibility support, and a dart runtime for developing, compiling as well as running Flutter applications. In addition, for rendering the low-level graphics, it uses Googles open-source graphics library called as Skia.

  • Flutter Framework:

The flutter framework is a bridge between developer and flutter. Flutter framework provides an advance reactive framework. Dart language is used for creating the Flutter framework. It contains foundational libraries, rendering libraries, widget libraries and last but not the least “Material” and “Cupertino” libraries. Use of these layers of libraries are as below:

  1. Material and Cupertino libraries: With help of this library create the code for android as well as iOS. This library defines such classes and set of controls.
  2. Widget libraries: This library gives permission to define combination of classes that can be reused. On the other hand, this layer introduces the reactive programming model.
  3. Rendering libraries: It gives an idea to deal with the layout. Therefore, using this library one can create a tree of renderable objects.
  4. Foundational libraries: It includes the services like animation, painting and gestures that uses ideas on the top of primary foundation.
  • Platform embedder:

The platform embedder is the native operating system application that entertains all flutter data. In addition, it acts as a bridge between the given operating system and flutter. In the beginning it provides the starting point, manages the threads for UI and similarly creates a layer where flutter can write. As well as it initiates the flutter engine at the same time. This multi-featured Flutter contains the platform embedding for multiple operating systems. The operating systems such as Android, iOS, Windows, macOS and also in Linux. Flutter is much more flexible that beyond these operating systems you can also create a custom platform embedder for example in Raspberry Pi.
