block 1.0.0

Blob-compatible binary data blocks with platform-optimized implementations for web and io.

1.0.0

Released: 2026-02-06

BREAKING CHANGES

• Reset the package to a minimal Blob-compatible API:
  • Block(List<Object> parts, {String type = ''})
  • size, type, slice(), arrayBuffer(), text(), stream()
• Removed legacy memory/cache/dedup/public management APIs.
• Removed legacy helper exports (MemoryManager, DataStore, DisposableBlock, ByteDataView, etc.).

Added

• Platform-specialized implementations under one package via conditional imports.
• web implementation that wraps native Blob (package:web).
• io implementation using temp files + finalizer cleanup.
• io slice strategy:
  • copy for <= 64KB
  • shared backing for > 64KB
• New VM/web contract tests and Flutter integration test coverage.
