Well it's a plugin for interacting with Accessibility Service in Android. This will probably crash if called in iOS device.
There are only 5 functions implemented:
serviceStatus: check if the service is online.
requestToStartService: open an intent to Accessibility Settings, that's all
stopService: stop the Accessibility service.
setCallbackOnAccessibilityEvent: set a callback when an
AccessibiltyEventis received. Only static or top-level callback is accepted. Please call this before starting the service.
setupFilterAccessibilityEvents: set a filter to choose which kind of events we want to react.
