`showDirections` on Google Maps on iOS doesn't work with waypoints

[luckyhandler]

I'm using map_launcher: ^2.1.1

When opening showDirections with waypoints in Google Maps on iOS I'm stuck on the following screen

The code I'm using is

  await map.showDirections(
    origin: Coords(
      departure.latitude,
      departure.longitude,
    ),
    originTitle: departure.address?.urydeAddressStringMedium ?? '',
    destination: Coords(
      destination.latitude,
      destination.longitude,
    ),
    destinationTitle: destination.address?.urydeAddressStringMedium ?? '',
    waypoints: waypoints.map((e) => Coords(e.latitude, e.longitude)).toList(),
    directionsMode: rideType == RideType.passenger
        ? DirectionsMode.walking
        : DirectionsMode.driving,
  );

if waypoints is assigned an empty list or null it works.

On Android the same code works.

The coordinates I'm using are lat: 49.48896, lng: 10.94142 and lat: 49.46992, lng: 11.00541. I added a screenshot of the waypoint list content:

Any idea what causes the issue?

Sorry for taking so much time to test this. I have tried on iOS with the coordinates you provided and it seems to work fine. Is this still an issue for you? If yes, what happens when you click the "Continue" button? And could you provide some more info for me to test on my side?

I've tested again and it seems to be ok. Let me know if it's still an issue
