Project description:
"I run a live game app built with Flutter that already ships on both iOS and Android. The next update introduces a timed karaoke song challenge: where players get 25 seconds of a karaoke clip, complete with scrolling lyrics, and must sing along as a challenge within the game. AFter this other game players vote on whether the singer gets to stay in game or not (This voting functionality is already embedded in the game).

Here is what has to happen:

• On demand the app calls our SQL-based catalogue, retrieves the paired MP3 and CDG files for the chosen song, then streams or caches them locally.
• The CDG lyric data must stay frame-perfectly synced with the audio so the words highlight in time on the Flutter front end.
• After exactly 25 seconds playback stops and control hands back to the existing game logic that scores the answer.

Please give me:

1. Clean, well-documented Flutter/Dart code added to the current project so the feature compiles for both iOS and Android.
2. A lightweight service or helper that handles CDG decoding, MP3 playback, lyric timing, and the 25-second cutoff.
3. Any database queries or schema tweaks needed to locate and serve the song assets.
4. A short read-me explaining new dependencies, platform permissions, and how to add more tracks in the future.

If you have prior experience with audio/video sync, karaoke libraries, or CDG parsing in Flutter, that will make this collaboration move much faster. I can supply sample CDG/MP3 pairs and direct database access as soon as we start.

Please see possible codeing steps in attached file." (client-provided description)
