Switch ThumbColor with React-Native

I would like to make a switch on my app with react-native. The switch should look like this switch as demonstrated below:

I've tried with Linear Gradient with unsuccessful

<Switch                    trackColor={{ false: Colors.GrayTransparent, true: Colors.GrayTransparent }}                    ios_backgroundColor='#3e3e3e'                    onValueChange={toggleSwitch}                    value={isEnabled}                    thumbColor={                        isEnabled ? (<LinearGradient                                start={{ x: 0, y: 0 }}                                end={{ x: 1, y: 1 }}                                colors={['#EED02D', '#9A4A90', '#EB9D27', '#4B77B6', '#C43438', '#C43438']}                            />                        ) : (                            Colors.Blue                        )                    }                />

Thank you a lot :)
