iOS Crash on showMarker [canOpenURL: failed for URL]

[samuele-besoli-mndl]

Hello, I'm using this package as it follow

final availableMaps = await MapLauncher.installedMaps;
if (availableMaps.length > 1) {
  MapsSheet.show(
    context: context,
    onMapTap: (map) {
      map.showMarker(
        coords: Coords(
          details.location.position.latitude,
          details.location.position.longitude,
        ),
        title: details.address,
      );
      Navigator.pop(context);
    },
  );
} else {
  availableMaps.first.showMarker(
    coords: Coords(
      details.location.position.latitude,
      details.location.position.longitude,
    ),
    title: details.address,
  );
}

So I show MapsSheet if there are more maps app installed, else I launch the only one installed.

The problem is when code is on map.showMarker the app crash with this error on console.

My info.plist is ok because I already added this.

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>comgooglemaps</string>
  <string>baidumap</string>
  <string>iosamap</string>
  <string>waze</string>

  <string>osmandmaps</string>
  <string>dgis</string>
  <string>qqmap</string>
  <string>here-location</string>
</array>

Let me know if I'm doing wrong.

Thank you :)

I found the problem! In some cases details.address was null so I was passing title: null and this caused the crash.
