player_watermark

A zero-dependency Flutter widget that overlays a semi-transparent text watermark on any video player or widget in real time.

---

Overview

player_watermark renders a live text label — username, email, user ID — over any Flutter widget without touching a video file. It is designed for video players, but works on any widget.

Unlike FFmpeg-based watermark packages that process and re-encode video files, player_watermark is a pure Flutter Stack overlay. There is no processing delay, no temporary files, and no platform channels.

Touch events pass through the watermark layer. The underlying player remains fully interactive.
