Flutter Mobile App Development Case Study: Once in Vilnius Community Media Platform

Project Overview

Once in Vilnius is a community-driven mobile application developed by Logicnord to collect and curate user-generated video stories during the 700th anniversary of Vilnius, the capital of Lithuania.

The platform invited residents, tourists and city enthusiasts to document their experiences in Vilnius by uploading photos and videos directly from their mobile devices.

Logicnord was responsible for the full development of the platform, including the Flutter mobile application and backend infrastructure that supported media uploads, social interaction and content moderation.

User-generated content collected through the platform was later curated by professional filmmakers and used in the documentary film "Once Upon a Time in Vilnius".

The project received international recognition and won the Intermedia-Globe Gold Award at the WorldMediaFestivals in Hamburg in 2024.
