Chapter 6

1. We use the flame_audio library to add audio to our games.
2. Loading audio into a memory cache ahead of time improves your game's performance, as we are usually going to play the same sound effects many times in the game.
3. We need to clear the buffer to prevent holding onto the resource and causing memory leaks, which may crash our game.
4. We need to listen for pause events when the game is backgrounded and resume events when the game is brought back into focus.
5. We need to store a reference to the AudioPlayer that is returned for longer sound effects, so we can control the sound if the game is paused or resumed.
6. We use the volume parameter passed to the play function of FlameAudio.
