How to create Dart packages for Flutter

The tutorial provides a comprehensive guide to creating and sharing Dart packages for Flutter applications, using the Dart programming language for cross-platform development. It explains the types of Dart packages—regular and plugin packages—and details the process of building a Flutter package, from initializing a Git repository to writing a custom Flutter widget called CustomButton. The guide then instructs on testing the package locally by creating an example Flutter project and finally publishing the package on pub.dev for global access by other developers. It emphasizes the importance of Dart packages in avoiding repetitive coding tasks by leveraging existing solutions, thus allowing developers to focus more on the core logic of their applications.
