Education, event planning, business, health, and government have all benefited from the fast spread of increasingly complex and quick information technology. This technology is crucial in ensuring the organization functions more successfully and efficiently when an event is held. The conventional approach frequently acts as a hindrance and slows down the operation. This problem can be resolved by substituting QR codes for tickets and e-certificates and employing e-registration technologies instead.

The most effective solution for event organizers to handle these problems may be smartphones and other cellular technology. The Event Registration System, which combines QR Code and e-registration technology for registration and credential validation, is a simple and effective way to implement the stages of event procurement. The flutter framework serves as the foundation for this Dart-based project. The programming language Dart is one that Google created and maintains. Flutter is a cross-platform framework for creating high-performance mobile apps.

This system has two categories of users: administrators and registrars. The admin is in charge of all data storage in the system, including the user list, events, and audience. The administrator can export the audience list to Excel for each event.

The volunteer or registrant is responsible for scanning and storing the event's audience or attendees. The list of events assigned to the volunteer can be seen here. The Event Registration System with QR Code features an attractive user interface and more functionalities.
