I had the same error when testing the camera_tizen plugin and here's an easy fix:

diff --git a/packages/video_player/tizen/src/video_player.cc b/packages/video_player/tizen/src/video_player.cc

 }

(You may change the error tag and error message as you want.)

I'll take care of this issue if you haven't done yet.
