Abstract
In the rapidly evolving landscape of mobile application development, Flutter has emerged as a robust framework for creating high-performance, cross-platform apps. This article explores best practices in architecture and state management within Flutter applications, with a particular focus on developing educational tools for Kazakh children to learn about their cultural heritage. We delve into architectural patterns that enhance code maintainability and scalability, such as MVVM and Clean Architecture. Additionally, we examine various state management solutions, including Provider, Bloc and Riverpod, comparing their strengths and use cases. The study highlights the collaborative efforts of the development team, demonstrating how effective teamwork and role allocation can lead to the successful implementation of a portable and user-friendly application. By eliminating the existing gap in educational resources adapted for children, this Flutter-based application offers a free and accessible platform for learning Kazakh traditions.
