What KeepAlive does is different from the Offstage widget. Let's not confuse these two and be more speicific in the wording for KeepAlive.

This modifies our flutter_tools crash reports to include the error
message. This error message may contain personally identifying
information (PII), such as a file system path on the developer's
local machine that may contain user names, project code names,
etc. To disable crash reporting, the developer can run the
following command:

    flutter config --no-analytics

For more information on what gets reported during crashes of the
flutter tool, see:

In Dart 2, asserts no longer accept non-bool values so this rule is
made redundant by the Dart analyzer's basic checks and is no longer
necessary.

The rule will be removed in a future Linter release.
