║ Welcome to Flutter! - https://flutter.dev ║

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