The Car is still taking pause for the next coordinate. How to get the smooth movement of marker from one coordinate to another ?

@ghost are you solve it?

@ghost are you solve it?

I have the same issue @ghost, Can you advise me any solution?

The Car is still taking pause for the next coordinate. How to get the smooth movement of marker from one coordinate to another ?

@ghost I have solved it, you need to following code:

this.state.coordinate.timing({
latitude: location.latitude,
longitude: location.longitude,
latitudeDelta: LATITUDE_DELTA,
longitudeDelta: LONGITUDE_DELTA,
duration
}).start()

I get this error while runnig this code

"dependencies": {
"react": "16.11.0",
"react-native": "0.62.2",
"react-native-maps": "0.27.1"
},

Windows10

Emulator = Pixel_3a_API_R

@dilipsuthar97 did you figure out the solution to the error?

@AnetteVestvik yes I got the solution for the above error. You just have to add value for latitudeDelta and longitudeDelta in coordinates object inside MapView and Marker as well.
If you r using animated mapview and marker than you probably have to add this.

const { width, height } = Dimensions.get('window');
const ASPECT_RATIO = width / height;
const LATITUDE_DELTA = 0.0922;
const LONGITUDE_DELTA = LATITUDE_DELTA * ASPECT_RATIO;

state = {
    region: new AnimatedRegion({
      latitude: 0,
      longitude: 0,
      latitudeDelta: LATITUDE_DELTA,
      longitudeDelta: LONGITUDE_DELTA,
    }),
    coordinate: new AnimatedRegion({
      latitude: 0,
      longitude: 0,
      latitudeDelta: LATITUDE_DELTA,
      longitudeDelta: LONGITUDE_DELTA,
    }),
  };

And If you'r updating the value of coordinates than you should add latitudeDelta and longitudeDelta

this.state.coordinate.setValue({
      latitude: lat,
      longitude: long,
      latitudeDelta: LATITUDE_DELTA,
      longitudeDelta: LONGITUDE_DELTA,
});

I hope it'll help you

The Marker does not move anymore, seems like because https://routedata-api-moxccjjiez.now.sh is unavailable now

How can I do it with function Components??
