After making substantive changes to Dart code, ALWAYS run flutter analyze to catch errors, warnings, and deprecations.
Flutter evolves rapidly. You must be aware of and prefer modern language features and APIs over outdated ones, even if the analyzer doesn't strictly forbid the old ones yet.
Common Deprecations to Watch:
.withValues(alpha: ...) over .withOpacity(...)..toARGB32() over .value for Colors.activeThumbColor over activeColor in Switches.LLMs often default to older patterns found in their training data.
WillPopScope, Opacity, etc.) has a newer replacement (like PopScope, withValues).flutter analyze flags a deprecation, treat it as an error to be fixed immediately.
