Props

You can configure your axis pad in react-native props : (All options are optional)

    size: Integer,              // Wrapper circle size. Default: 300
    handlerSize : Intager,      // Handler circle size. Default: 150
    wrapperStyle : Object,      // Wrapper circle styles.
    handlerStyle : Object,      // Handler circle styles.
    step: Float,                // Step size for values. Default: 0
    lockX: Boolean,             // Block to X axis movement. Default: false
    lockY: Boolean,             // Block to Y axis movement. Default: false
    autoCenter: Boolean,        // Move wrapper to center of your touch area. Default: false 
    resetOnRelease: Boolean     // Set (0,0) position on touch end.  Default: false
    onValue: Function           // callback: returned values { x:Float, y:Float }
