silly style nit: curious about the mix between cascades and non-cascades. IMO,
it'd be better to go all in on either one. Dartformat will do a better job if
it's one big cascade:

new File(outputFile)
  ..createSync(recursive: true)
  ..openSync(mode: FileMode.WRITE)
  ...


This would work too:

var file = new File(outputFile);
file.createSync(recursive: true);
file.openSync(mode: FileMode.WRITE);
file. ...

Done.
