Volume Controller

This plugin allows you to control and listen to the system volume on your device. It provides a simple API to get, set and monitor the system volume.

Notes

For iOS, you need to test on a real device as the simulator does not support volume control.

Functions

GetVolume

Get the current volume from the system

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

SetVolume

Set the system volume. The input is a double number in the range [0.0, 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 if the system volume is muted. On iOS and Android, this checks if the volume level is equal to 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);
