Calling setState() in the onDirectionChanged property will make the joystick not working... #26

Hey, Is there a way to call setState in the onDirecitonChanged callback or is there another way to do it ? Thanks :)

+1. It seems any call to setState that triggers constructing a new JoystickView widget makes it return to the (0, 0) position. E.g., I set a timer that calls setState every 100 milliseconds. Then it works for those 100 milliseconds, then when the setState call is triggered and the parent widget is rebuilt, the JoystickView gets back to (0, 0).
