blake3_ffi: ^0.2.2 copied to clipboard

• Widen the native-toolchain constraints so the package can be installed in a Flutter app at all. hooks 2.1.0 and native_toolchain_c 0.19.3 raised their meta floor to ^1.19.0, and Flutter's SDK pins meta to 1.17.0, so flutter pub add failed at version solving with "flutter from sdk is incompatible". Allowing hooks >=2.0.2 and native_toolchain_c >=0.19.2 lets the solver pick a version that works with the pinned meta, while a pure-Dart project still resolves to the newest. No API or behaviour change.

• Declare the benchmark chart in pubspec.yaml so pub.dev renders it on the package page. The chart was already in the repository and the README, but pub.dev shows only what the screenshots: field points at, so the page a reader lands on from search opened with text where the measurement should have been.

• Add blake3Stream and blake3HexStream: one call to hash a Stream<List<int>> (a file's openRead(), an upload, any byte stream) as it arrives, without holding the whole input in memory. Each drives a Blake3Hasher internally and disposes it when the stream ends. This is the memory-safe way to hash something too large to load at once, and unlike a SHA-256 stream from package:crypto it runs at BLAKE3's throughput. The outputLength (XOF) argument carries through.

• Add hex variants for the raw-output paths: blake3KeyedHex, blake3DeriveKeyHex, and Blake3Hasher.finalizeHex. Keyed, derived, and streamed digests now format to hex the way blake3Hex already does, so callers stop re-implementing it (the example used to).

• Docs: sharpen the pub.dev description to lead with the value and the terms people search.

Initial release, vendoring the official BLAKE3 C implementation 1.8.5.

• One-shot hashing: blake3, blake3Hex.
• Streaming hashing: Blake3Hasher with update, finalize, reset, and dispose.
• Keyed hashing (MAC/PRF): blake3Keyed, Blake3Hasher.keyed.
• Key derivation (KDF): blake3DeriveKey, Blake3Hasher.deriveKey.
• Extendable output (XOF) via outputLength and seek.
• Native code builds automatically via Dart build hooks (Dart 3.10+); no manual native setup. arm64 uses the NEON kernel; other architectures use the portable C kernel.
• Verified against the official BLAKE3 test vectors (default, keyed, and derive-key modes, extended output, and streaming).
