Looping Background Music¶
Bgm class, you can manage looping of background music tracks with regards to application
(or game) lifecycle state changes.
When the application is terminated, or sent to background,
Bgm will automatically pause
the currently playing music track. Similarly, when the application is resumed,
Bgm will resume the
background music. Manually pausing and resuming your tracks is also supported.
For this class to function properly, the observer must be registered by calling the following:
IMPORTANT Note: The
initialize function must be called at a point in time where an instance of
WidgetsBinding class already exists. Best practice is to put this call inside of your game’s
In cases where you’re done with background music but still want to keep the application/game
running, use the
dispose function to remove the observer.
To play a looping background music track, run:
import 'package:flame_audio/flame_audio.dart'; FlameAudio.bgm.play('adventure-track.mp3');
You must have an appropriate folder structure and add the files to the
pubspec.yaml file, as
explained in Flame Audio documentation.
Caching music files¶
Bgm class will use the static instance of
FlameAudio for storing cached
music files by default.
So in order to pre-load music, you can use the same recommendations from the Flame Audio documentation.
You can optionally create your own
Bgm instances with different backing
if you so desire.
play function takes in a
String that should be a path that points to the location of the
music file to be played (following the Flame Audio folder structure requirements).
You can pass an additional optional
double parameter which is the
volume (defaults to
FlameAudio.bgm.play('music/world-map.mp3', volume: .25);
To stop a currently playing background music track, just call
Pause and Resume¶
To manually pause and resume background music you can use the
FlameAudio.bgm automatically handles pausing and resuming the currently playing background music
pausing prevents the app/game from auto-resuming when focus is given back to the
