Fails on Flutter 1.0 with iOS device

[RyanRamchandar]

I get the following error when using version great_circle_distance: ^1.0.1

final d1 = GreatCircleDistance.fromDegrees(
          latitude1: lat1,
          longitude1: lon1,
          latitude2: lat2,
          longitude2: lon2,
        ).haversineDistance();

Output

Same issue here. Did you solve it?

[RyanRamchandar]

Unfortunately no. I had to find an alternative solution for the time being.

Look at the PR's; The renaming of PI -> pi. For some reason the Travis build fails, but it's more to do with the Travis setup than the nature of the PR.
