detect_unused_code 1.3.2

A fast, zero-dependency Dart and Flutter dead code detector. Finds unused classes, imports, variables, dead code, commented-out files, and TODO tasks.

1.3.2

• Appended line number directly to the file path in the TODO console report (e.g. path/to/file.dart:line) enabling instant clickability in IDE terminals.

1.3.1

• Improved TODO comment scanner to capture all TODO tags across all comments, documentation comments (///), and inline notes, matching the Dart analyzer's dart(todo) diagnostic behavior in IDEs.

1.3.0

• Added comprehensive all-in-one default inspection covering 13 code quality points without requiring extra flags.
• Added Dart Analyzer diagnostics inspection:
  • unused_import: Unused imports across files.
  • unnecessary_import: Duplicate or redundant imports.
  • unused_local_variable: Unused local variables.
  • unused_field: Unused class fields.
  • unused_element: Unused private functions, methods, and elements.
  • dead_code: Unreachable dead code blocks.
  • dead_null_aware_expression: Unnecessary null-aware ?. operators on non-nullable targets.
• Added TODO task tracker: Detects pending // TODO: ... and /* TODO ... */ tasks with exact line numbers, descriptions, and clickable file URIs.
• Enabled file-internal only public classes analysis by default (includeInternal: true).
• Added fine-tuning flags: --todos-only, --diagnostics-only, --no-todos, --no-diagnostics, and --no-internal.
• Updated JSON report export (--json) to serialize all 13 inspection points and categorized diagnostics.
• Added TodoItemResult and DiagnosticIssueResult models with full dartdoc documentation.

1.2.0

• Added comprehensive dartdoc documentation comments across 100% of public API elements (classes, constructors, methods, and properties).
• Enclosed flow control statements in curly braces across all files to conform with curly_braces_in_flow_control_structures lint.
• Added analysis_options.yaml with package:lints/recommended.yaml and formatted all Dart files with dart format.

1.1.0

• Enhanced --json flag to automatically save the audit report as a .json file (detect_unused_code.json) in the current execution directory instead of printing raw JSON to the terminal.
• Added support for specifying a custom JSON output filename (e.g. --json=custom_report.json or --json custom_report.json).
• Added progress bar display during JSON analysis and a clean terminal summary showing the output file location upon completion.

1.0.0

• Initial release of detect_unused_code.
• Full project scan and path-specific scan (--url, --path, positional argument).
• Convenient short CLI command alias detect_unused.
• Detection of unused/dead classes, widgets, mixins, enums, controllers, and models.
• Detection of public classes with file-internal only usage (--include-internal).
• Detection of 100% commented-out files with extracted class names.
• Configurable thresholds for heavily commented files (--threshold).
• Configurable minimum line limits for commented code blocks (--min-lines).
• JSON output format support for CI/CD pipelines (--json).
• Zero external runtime dependencies.
• Programmatic API via UnusedCodeAuditor.
• Broad SDK compatibility (>=2.17.0 <4.0.0).
