POSTECH UGRP is one of the meaningful activities in POSTECH, which undergraduates team up with POSTECH to proactively decide research topics and study them for a year. Our team won the Grand Prize for a year of research under the theme Research Subject: A Study on the Extended PAMS System Using NFT, which improves some problems of PAMS (POSTECH Activity Management System) and implements our own system as an mobile application. So I share you the source code of our app. It is based on the DART and Flutter framework, and used the Firestore database. I hope our work will be of great reference to you! Thank you.
