Dart is a versatile programming language that can be used for various purposes. Here are some common use cases of Dart:

1. Web development : Dart can be used to build web applications, both on the client-side and server-side. With frameworks like AngularDart and Aqueduct, developers can create responsive and interactive web interfaces and build scalable server applications.

2. Mobile app development : Dart is the primary language for developing mobile applications using the Flutter framework. Flutter allows developers to build cross-platform mobile apps for iOS and Android using a single codebase. Dart's hot-reload feature in Flutter enables fast development and iteration cycles.

3. Desktop app development : Dart can be used to create desktop applications for Windows, macOS, and Linux using the Flutter framework. Flutter provides a rich set of UI components and allows developers to build high-performance and visually appealing desktop apps.

4. Command-line tools : Dart can be used to build command-line applications for automating tasks, running scripts, or building custom tools. Dart's extensive standard library and packages make it convenient for creating command-line interfaces and interacting with the file system and network. 5. Server-side development : Dart can be used to build server applications and backend services. The Aqueduct framework provides a robust set of tools and libraries for building scalable and high-performance server applications using Dart.

6. Internet of Things (IoT) : Dart can be used to develop applications and firmware for IoT devices. It provides a compact runtime, low-level system access, and support for networking protocols, making it suitable for IoT development.

7. Game development : While not as widely used as other game development languages, Dart can be utilized for developing games using frameworks like Flame. Dart's performance, ease of use, and support for 2D game development make it a viable option for game development projects.

8. Scripting and automation : Dart can be used as a scripting language for automation tasks, build scripts, or server administration tasks. Dart's simplicity, expressiveness, and tooling support make it an attractive choice for scripting purposes.
