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]. 1. 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`.
