Diagnostic Execution

Execute the Dart analyzer to identify static errors, warnings, and informational diagnostics across the codebase.

• Run $ dart analyze to evaluate all Dart files in the current directory.
• Target specific directories or files by appending the path: $ dart analyze bin or $ dart analyze lib/main.dart.
• Enforce strictness by failing on info-level issues using the --fatal-infos flag.
• Apply automated quick-fixes for supported diagnostics using $ dart fix --apply. Preview changes first with $ dart fix --dry-run.
