FlutterDonor: A Cross-Platform Mobile Application for Real-Time Organ Donor Recipient Matching Using Flutter and Firebase

Organ donation is a critical intervention in modern healthcare, yet the global shortage of
organ donors continues to result in preventable deaths among patients awaiting transplantation.
Conventional donor registration frameworks are slow, paper-dependent, and geographically
constrained. This paper presents FlutterDonor, a cross-platform mobile application developed using
Google’s Flutter framework and Firebase cloud services, designed to digitize and streamline organ
donor-recipient matching. The system provides a real-time donor registry, blood-group and organ
type filtering, anonymous or phone-authenticated user access, and a recipient request portal with
urgency-level classification. Backed by Firebase Firestore for data persistence and Firebase
Authentication for access control, the application demonstrates a practical, scalable solution for
reducing organ-shortage waiting times. Performance evaluations and architectural analysis confirm
the suitability of Flutter and Firebase as a combined stack for social healthcare applications.
