sound property

String? sound

The sound to play when a recipient receives a push notification that's based on the message template. You can use the default stream or specify the file name of a sound resource that's bundled in your app. On an Android platform, the sound file must reside in /res/raw/.

For an iOS platform, this value is the key for the name of a sound file in your app's main bundle or the Library/Sounds folder in your app's data container. If the sound file can't be found or you specify default for the value, the system plays the default alert sound.

Implementation

final String? sound;
