Code Review

This pull request adds a new analytics event analysisStatistics for the Dart analyzer. The changes include adding a new enum value in DashEvent and a corresponding named constructor in the Event class. The implementation looks correct and follows existing patterns. My main feedback is to add tests for the new event constructor to ensure its correctness and maintain test coverage.

[gemini-code-assist]

This new constructor should be tested to ensure it's constructed correctly with the expected eventName and eventData.¹

Please add a unit test for Event.analysisStatistics in pkgs/unified_analytics/test/event_test.dart. For example:

  test('Event.analysisStatistics constructed', () {
    Event generateEvent() => Event.analysisStatistics(
          workingDuration: 'test duration',
        );

    final constructedEvent = generateEvent();

    expect(generateEvent, returnsNormally);
    expect(constructedEvent.eventName, DashEvent.analysisStatistics);
    expect(constructedEvent.eventData['workingDuration'], 'test duration');
    expect(constructedEvent.eventData.length, 1);
  });

Additionally, you'll likely need to update the test Confirm all constructors were checked in the same file, which uses reflection to ensure all public Event constructors have corresponding tests.
