Code must be formatted using dartfmt.
To format your files, just run format_check.sh or:
dartfmt --fix --overwrite .
The CI test uses dartanalyzer to check the library for improvements. IF

To test the dart version first download the dart sdk from Dart main site and run this from the repository root directory:
~/open-location-code$ cd dart && pub run test
