The author wrote this book with the goal of elevating beginner-level skills to a professional level. It enables learners to immediately apply theoretical knowledge by creating practical apps with genuinely useful functions. Each app is developed by demonstrating the process, just as it would be implemented in a real project setting, rather than simply presenting the final result. Changes and modifications to the code are clearly highlighted to make it easy to follow along.

By adhering to a structured sequence—[Project Introduction] → [Prerequisite Knowledge] → [Preparation] → [UI Design] → [Implementation] → [Testing]—the book systematically guides readers through app development. Designed for beginners, it covers everything from an introduction to the Dart language to development, advertising, and deployment, providing practical and industry-relevant insights. As a result, readers will experience a solid yet rapid skill improvement.
