Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

1. Run the Dart SDK's flutter-analyze bot.
2. See failure: https://logs.chromium.org/logs/dart/buildbucket/cr-buildbucket/8783492984983413121/+/u/analyze_flutter_flutter/stdout?format=raw

Expected results

Not failure.

The expected fix should not have code like var TextTheme copiedTextTheme =, which is not valid code.

Actual results

Failure.
