A Cross-Platform Doctor Prebooking System Using Flutter and Firebase for Efficient Healthcare Scheduling

In today’s age of digital transformation, the healthcare sector is swiftly adopting mobile technologies to improve accessibility, efficiency, and patient satisfaction. A key element of healthcare management is appointment scheduling, which has traditionally depended on manual communication via phone calls or face-to-face visits. These methods frequently result in inefficiencies, scheduling mistakes, prolonged waiting times, and patient dissatisfaction. To address these challenges, this study introduces a Cross-Platform Doctor Prebooking System that utilizes Flutter for frontend development and Firebase for backend integration. Flutter facilitates the development of high- performance mobile applications with a unified codebase, ensuring a consistent user experience across both Android and iOS platforms. Firebase offers real-time database updates, secure authentication, and cloud-based notification services, making it a powerful backend solution for scalable healthcare applications. The proposed system enables patients to easily register, browse doctor profiles organized by specialization, and book appointments instantly from their mobile devices. Real-time synchronization guarantees that appointment availability is automatically refreshed across all connected users, thus preventing double bookings or missed slots. Doctors can efficiently manage their schedules by accepting, rescheduling, or canceling appointments, while patients receive immediate notifications and reminders through Firebase Cloud Messaging. The architecture of the system ensures secure, real-time, and reliable data management, minimizing administrative burdens and enhancing workflow efficiency within healthcare organizations. Experimental evaluation of the prototype validates its effectiveness regarding speed, responsiveness, and user satisfaction. The average data synchronization latency was recorded at under 150 milliseconds, showcasing its potential for real-world application in busy clinical settings. Additionally, the implementation of cloud- based infrastructure guarantees scalability, facilitating smooth integration with various healthcare services like teleconsultation and electronic health record (EHR) systems. In summary, this study highlights the increasing significance of mobile healthcare applications and demonstrates how the synergy of Flutter and Firebase technologies can transform appointment scheduling, improve operational efficiency, and deliver patient-focused care within the digital healthcare environment.
