Dart CLI

Dart CLI

Dart CLI (Command Line Interface) is a powerful tool that offers developers a command-line interface for building, running, and managing Dart applications. With Dart CLI, developers can efficiently interact with their Dart projects, execute scripts, and perform various development tasks from the command line.

Installation

To use Dart CLI, you need to have Dart SDK installed. If you haven't installed Dart SDK yet, refer to the Dart SDK Installation guide for detailed instructions.

Getting Started

With Dart CLI, you can create a new Dart project effortlessly. To create a new project, use the following command:

```shell dart create <project_name> ```

Replace `<project_name>` with the desired name for your project.

After creating a Dart project, you can navigate to the project directory using the `cd` command. For example:

```shell cd <project_name> ```

Building and Running Dart Applications

To build a Dart application, use the following command:

```shell dart compile exe <entry_point.dart> ```

Replace `<entry_point.dart>` with the filename of the main Dart file (entry point) of your application. This command compiles the Dart code and generates an executable file that can be run in the command line.

To run a Dart script without building an executable, use the following command:

```shell dart run <script.dart> ```

Replace `<script.dart>` with the filename of your Dart script.

Managing Dependencies

Dart CLI provides a robust dependency management system called Pub. With Pub, you can easily manage packages and their versions in your Dart projects.

To add a dependency to your project, create or modify the `pubspec.yaml` file in your project directory. Add the desired package and version to the `dependencies` section. For example:

```yaml dependencies:

 http: ^3.0.0

```

After modifying the `pubspec.yaml` file, run the following command to fetch and update the dependencies:

```shell dart pub get ```

This command retrieves the specified package from the Pub website and makes it available for your project to use.

Additional Dart CLI Commands

Dart CLI offers additional commands and functionalities that can assist you in various development tasks. Here are some notable commands and their usages:

- `dart analyze`: Performs static analysis on your Dart code, highlighting potential issues and suggestions for improvement.

- `dart format`: Automatically formats your Dart code according to the Dart style guidelines.

- `dart test`: Runs tests defined in your Dart project to ensure the correctness of your code.

For a comprehensive list of Dart CLI commands, refer to the Dart CLI Command Reference.

Conclusion

With Dart CLI, developers have a versatile command-line interface at their disposal, enabling efficient development, testing, and management of Dart applications. By familiarizing yourself with the Dart CLI tools and commands, you can streamline your development workflow and enhance your productivity.
