How do I get a linear gradient in strokeColor props

I am trying to create a linear gradient on the stroke of maps. Currently this is my attempt by far, which failed too.

```


}
timePrecision={"now"}
onReady={data => {
console.log('ONREADY DATA: ', data);
setDuration(data.duration);
setDistance(data.distance * 0.621371);
setCarAngle(calculateAngle(data.coordinates));
getTripStatus(tripInfo.ID, username, password)
}}
/>
```

This is the result I am looking for is
