Flutter reports data to two separate systems:

1. Anonymous usage statistics are reported to Google Analytics (for statistics such as the number of times the flutter tool was run within a given time period). The code that manages this is in [usage.dart].
2. Crash reports for the flutter tool. These are not reports of when Flutter applications crash, but rather when the command-line flutter tool itself crashes. The code that manages this is in [crash_reporting.dart].

Opting out

Users can opt out of all reporting in a single place by running flutter config --no-analytics.
