Dependency Management

Dependency management is an essential aspect of any software development project. It involves managing the external libraries or packages that your project relies on to function correctly. In Dart, you can use a tool called pub and a configuration file called pubspec.yaml to manage dependencies for your project.

Project - Console Dictionary

Create a dart console dictionary, that accepts a word and prints the definition and other information about the word to the console.

Packages: https://pub.dev/packages/owlbot_dart (SDK for free dictionary API)

By the end of this day, you should have a good understanding of how to use pub and pubspec to manage dart project dependencies. And learn the basics of how to import and use packages in Dart

Tips

• pub is a package manager that comes bundled with the Dart SDK, and it allows you to search for and download external packages from the Dart package repository. You can also use it to install, upgrade, and remove packages as needed for your project.

• The pubspec.yaml file is where you define your project’s dependencies and other metadata about your project, such as its name, version, and description. This file is used by pub to manage your project’s dependencies and ensure that your project has the correct versions of packages installed.

• To import and use packages in your Dart project, you can use the import statement to bring in the package’s functionality into your project. For example, to use the http package, you would add the following line to your Dart file:

import 'package:http/http.dart';

This would allow you to use the http package’s functions and classes in your code.
