Associate a pointing device to this cursor.

A mouse cursor class usually has a corresponding MouseCursorSession class, and instantiates such class in this method.

This method is called each time a pointing device starts displaying this cursor. A given cursor can be displayed by multiple devices at the same time, in which case this method will be called separately for each device.

Implementation

@protected
@override
MouseCursorSession createSession(int device) {
  return resolve(<MaterialState>{}).createSession(device);
}
