downloadx 0.3.0

An IDM-style download manager for Dart and Flutter — parallel chunked downloads, dynamic splitting, resume across restarts, and pluggable I/O.

0.3.0

• HLS unified into the chunk pipeline. Each HLS segment is now downloaded as an isSegment Chunk through the normal driveChunks path (parallelism capped at targetChunkCount), then concatenated. HLS downloads now get speed tracking, resume, retry, throttle and the full event system for free.
  • HlsSession reduced to playlist resolution + concat + cleanup (resolve / registerStreams / concat / cleanup / segDir / segPath).
  • Segment-based progress: percent and ETA derived from completed segments; hlsSegmentsDone / hlsTotalSegments reported on progress events and describe().
  • Resume re-resolves the playlist each run and skips already-downloaded segment files.
• DownloadOptions gained description and metadata — persisted and returned from describe(), with no behavioural effect (for host apps to attach notes, source links, etc.).

0.2.0

• Expanded dartdoc coverage across the full public API (100% of exported symbols).
• Added enum value documentation for ChunkMode, DownloadState, ChunkStatus, ChunkQuality, SplitReason, and DiagnosticLevel.

0.1.0

• Initial release.
• Chunked parallel downloads with dynamic splitting and resume support.
• HLS (m3u8) support: master/media playlist parsing, parallel segment download, optional ffmpeg concat via concatSegments hook.
• DownloadOptions supports minChunkSize and journal per-download overrides.
• Zero third-party dependencies.
