Upgrade latlong version from 0.4.0 to 0.5.3

[AlexandreRoba]

After upgrading to flutter 0.5.8-pre.155 I'm getting an error on missing math.PI (which was obsolete)

flutter version:

Flutter 0.5.8-pre.155 • channel master • https://github.com/flutter/flutter.git
Framework • revision 78a00cb13a (6 days ago) • 2018-08-01 22:56:49 -0700
Engine • revision a61fae0824
Tools • Dart 2.0.0-dev.69.3.flutter-937ee2e8ca

And the error:
