Broken Widget in Golden Test Output

[ajaxspace]

Problem:
The golden test for the dark mode variant of the molecules_collection renders a red error widget, indicating a runtime failure during widget build or layout.

📍 File:
flutter_styleguide/test/golden/failures/molecules_collection_dark_testImage.png

🟥 The presence of the red error box (typically with "Error building widget" or similar) means:

• The widget did not build successfully
• The test captured a runtime UI failure, not just a visual diff

🔍 Action Needed

• Run the test locally and inspect the console/log output to determine the actual exception.
• Common causes:
  • Null or missing data
  • Theme or context issues
  • Broken layout constraints
  • Misconfigured test setup
