dart.rs

//! Parser for Dart/Flutter pubspec.yaml and pubspec.lock files.
//!
//! Extracts package metadata and dependencies from Dart/Flutter project manifest
//! and lockfiles using YAML format.
//!
//! # Supported Formats
//! - pubspec.yaml (Dart package manifest)
//! - pubspec.lock (Dart package lockfile with pinned versions)
//!
//! # Key Features
//! - Dependency extraction from dependencies and dev_dependencies sections
//! - Direct vs transitive dependency tracking (lockfile)
//! - Version constraint parsing for Dart's SemVer and range specifiers
//! - Package URL (purl) generation for Pub packages
//! - Author/maintainer and homepage extraction
//!
//! # Implementation Notes
//! - Uses YAML parsing via `yaml_serde`
//! - Lockfile versions are pinned (`is_pinned: Some(true)`)
//! - Graceful error handling with `warn!()` logs
//! - Supports both pub.dev and Git-hosted packages
