PS C:\Users\Cristian\Desktop\airhopping> flutter build apk --tree-shake-icons --split-per-ab
Could not find an option named "split-per-ab".


Run 'flutter -h' (or 'flutter <command> -h') for available flutter commands and options.

  ║ The Flutter tool uses Google Analytics to anonymously report feature usage ║
  ║ statistics and basic crash reports. This data is used to help improve      ║

  ║ Flutter tool analytics are not sent on the very first run. To disable      ║
  ║ reporting, type 'flutter config --no-analytics'. To display the current    ║
  ║ setting, type 'flutter config'. If you opt out of analytics, an opt-out    ║
  ║ event will be sent, and then no further information will be sent by the    ║
  ║ Flutter tool.                                                              ║
