New portrait-poster APP with dark and light themes, modern technology, and category backgrounds in EFVCMS

I purchased a theme and rewrote most of its code to create this APP with portrait posters and freely switchable dark and light themes. It suits users whose film and series data is fully structured: every published video has detailed information such as ratings, release years, tags and portrait posters. The APP looks excellent, with images integrated into our own CDN and a local sqlite cache on the phone. Its smoothness compares favorably with major video platforms. It uses Flutter2 and dart16, and all source code complies with Null Safety. Download the APK to experience it. I wrote the source carefully according to high standards. A smaller update adds category background uploads to EFVCMS administration, supporting this portrait-poster APP.

This APP and the landscape-poster APP serve different needs. One suits content whose information cannot be fully edited; the other suits fully structured data, with posters, release regions, ratings, tags and related fields completed.
