Volume Controller

Control and observe the system volume on Android, iOS, macOS, Windows, and Linux.

Notes

• iOS volume control must be tested on a real device. The simulator does not support system volume control.
• showSystemUI is supported on Android and iOS only.
• On Android and iOS, isMuted() treats volume 0 as muted, and setMute(false) restores the previous volume saved by the plugin.

Variables

ShowSystemUI

Show or hide the volume system UI. The default value is true. Supported on iOS and Android only.

VolumeController.instance.showSystemUI = true;

Functions

GetVolume

Get the current system volume.

double volume = await VolumeController.instance.getVolume();

SetVolume

Set the system volume. The input should be in the range 0.0 to 1.0.

await VolumeController.instance.setVolume(double volume);

AddListener

Add a listener to monitor system volume changes.

• fetchInitialVolume: This parameter is optional and is used to fetch the initial volume when the listener is added. The default value is true.

VolumeController.instance.addListener((volume) {
  // Do something with the volume
}, fetchInitialVolume: true);

RemoveListener

Remove the volume listener.

VolumeController.instance.removeListener();

IsMuted

Check whether the system is muted. On iOS and Android, this checks whether the volume level is 0.

bool isMuted = await VolumeController.instance.isMuted();

SetMute

Mute or unmute the system volume. On iOS and Android, this sets the volume level to 0 and restores the previous volume level when unmuted.

await VolumeController.instance.setMute(bool mute);
