Online education platforms have grown rapidly due to the increasing demand for flexible and accessible learning experiences. As these platforms scale, choosing the right technology stack becomes essential for maintaining performance, security, and usability. Flutter, a modern cross-platform UI toolkit, provides an efficient way to build scalable mobile and web interfaces for online learning systems. SQL-based databases, on the other hand, offer strong consistency, normalized structures, and robust querying features that support large-scale content delivery, user management, and secure data storage. This paper explores the role of Flutter and SQL databases in building scalable online course platforms. Particular emphasis is placed on authentication, authorization, and security mechanisms. Code snippets, architectural diagrams, and theoretical explanations are provided to demonstrate best practices. The paper concludes by arguing that combining Flutter with SQL databases is a powerful approach to building secure, scalable, and maintainable online learning applications.
