6 Key Components of Flutter Architecture


Flutter is a free and open-source mobile app development framework created by Google. It uses the Dart programming language and provides a reactive programming model for building high-performance, high-fidelity, apps for iOS, Android, and the web. Flutter offers fast development with its hot reload feature, beautiful UI with its rich set of pre-designed widgets and animation libraries, and cross-platform capabilities for building apps for multiple platforms with a single codebase.

6 Key Components of Flutter Architecture

Flutter Engine

  • The underlying layer responsible for rendering the UI, managing graphics and animations, and executing Dart code.

Dart Platform

  • A programming language used in Flutter for building high-performance applications.


  • Reusable and customizable UI components that can be combined to build complex UIs.

Hot reload

  • A feature that allows developers to quickly view changes made in the code and make further changes, speeding up the development process.

Flutter Foundation Library

  • A collection of pre-designed widgets, tools, and APIs to support building high-quality apps.

Flutter Package Ecosystem

  • A vast collection of packages and plugins developed by the Flutter community, which can be easily integrated into projects.

Why flutter?

01.Fast Development

Hot reload feature enables fast development and saves time.

02.Beautiful UI

Flutter’s rich set of pre-designed widgets and animation libraries make it easy to create beautiful and responsive UI.

03.High Performance

Flutter’s use of Dart, a modern programming language, and its architecture provide high performance and smooth animations.

04.Community Support

Flutter has a growing community of developers and a rich ecosystem, with many open-source packages available.

05.Native Experience

Flutter’s widgets are designed to provide native experiences for both iOS and Android platforms.

06.Good for MVP

Flutter’s fast development cycle is ideal for building minimum viable products (MVPs) quickly.


Fast Development

Flutter’s hot reload feature enables developers to make changes in real-time, which significantly reduces the time needed to develop, test, and deploy apps.

Cross-platform Development

Flutter enables developers to build high-quality, native-like apps for both iOS and Android platforms with a single codebase, reducing the time, effort, and cost required for development.

High Performance

Flutter’s use of the Dart programming language and the Flutter framework delivers smooth and fast app performance, even on low-end devices.


User Experience

The framework offers a rich library of customizable widgets that provide a smooth, modern, and responsive user experience.


Flutter helps save costs as it eliminates the need to maintain separate codebases for iOS and Android platforms, and also reduces the time to market.

Growing Community

Flutter has a large, growing, and supportive developer community that continuously contributes to the framework, providing support and resources for app development.


Easy Integration

Flutter apps can easily integrate with existing systems and technologies, making it easier for businesses to adopt and use
