Flutter Architecture with components

Flutter follows a layered architecture pattern that separates the application into different layers, each responsible for specific tasks. This architecture pattern is called the Flutter Clean Architecture and it is inspired by the Clean Architecture principles.

Flutter Framework Layer

This layer provides a set of pre-built widgets and APIs that developers can use to build UI components, handle user input, and perform other common tasks in their apps.

Engine Layer

This layer is responsible for rendering graphics, managing the app's lifecycle, and handling platform-specific features such as camera access, networking, and location services.

Platform Layer

This layer provides access to the underlying platform's native features and functionality, allowing developers to access platform-specific APIs, integrate with other platform-specific libraries, and access hardware features like sensors, cameras, and microphones.

Dart Language Layer

This layer is the foundation of the Flutter framework and is responsible for providing the language and runtime environment that developers use to write their code.


The layered architecture of Flutter provides a high degree of separation of concerns, making it easier for developers to write clean and maintainable code. It also allows developers to customize and extend the framework as needed by building their own widgets, plugins, and packages on top of the core framework.
