 // scan_keys.dart
 
+// This script scans .dart files in the specified "lib" folder of a Flutter project,
+// extracts all Key(...) / ValueKey(...) usages, collects their occurrences (including
+// file path, line, and column), then generates a Markdown file ("keys_report.md")
+// that presents the data in a tabular format.
+//
+// How to use:
+//   dart run bin/scan_keys.dart <path_to_flutter_project_lib>
+//
+// Example:
+//   dart run bin/scan_keys.dart ./lib
+//
+// After running, a "keys_report.md" file will appear in the project root directory,
+// listing all the discovered Keys.
+//
+// Dependencies:
+//   In pubspec.yaml, ensure you have:
+//     dev_dependencies:
+//       analyzer: ^5.12.0 (or a version compatible with your Dart SDK)
