About

This plugins allows to listen for the events fired when the user presses the hardware volume up or down button of the device. An object that contains only one property is passed to the callback - see VolumeButtonsResult. This plugin contains code derived from or inspired by https://github.com/CipherBitCorp/VolumeButtonHandler and https://github.com/thiagobrez/capacitor-volume-buttons plugins.

Features:

• support receiving events when the volume is max or min (make sure to use disableSystemVolumeHandler on iOS platform - see VolumeButtonsOptions)
• keep receiving events after the application sent to and returns from the background
• supports Android and iOS platforms

NOTE: The plugin version 1.0.0 is compatible with Capacitor 5 which requires gradle version 8.0
