Dart bindings to libgit2

git2dart package provides ability to use libgit2 in Dart/Flutter.

Managed libgit2 lifecycle

The package owns native-library discovery and one checked libgit2 increment per Dart isolate. Use libgit2Runtime instead of constructing a second loader or calling the generated lifecycle methods directly:

import 'package:git2dart_binaries/git2dart_binaries.dart';

final features = libgit2Runtime.withCall(
  (bindings) => bindings.git_libgit2_features(),
);

final owner = libgit2Runtime.acquireOwner(debugLabel: 'repository');
owner.bindDestructor(() {
  // Destroy the native owner here.
});

owner.release(); // exact-once; fallback finalization uses the same token
final remainingNativeOwners = libgit2Runtime.shutdown();

shutdown() is synchronous, guarded by live calls/owners, idempotent after success, and terminal for the calling isolate. A positive return value is valid when another isolate or external native consumer still owns an increment.

The generated Libgit2.git_libgit2_init() and Libgit2.git_libgit2_shutdown() methods remain available as raw ABI, but direct consumer calls are unsupported because they bypass package accounting. The former eager libgit2 and libgit2Opts globals were removed intentionally; backward source compatibility is not provided.

Ffigen

To generate bindings with ffigen use (adjust paths to yours):

dart run ffigen --compiler-opts "-I/path/to/git2dart/libgit2/headers/ -I/lib64/clang/12.0.1/include"

Validation evidence

The validation suite distinguishes evidence instead of treating an unavailable native prerequisite as a pass:

• Host-independent tests execute the cache-manifest and platform-proof CLIs, Android TLS state transitions, the exact-pinned analyzer AST policy, and the parsed workflow graph.
• Native ABI, loader, and expanded-package tests require an explicitly injected binding and matching platform payload. A missing payload is reported as unavailable; it is not native success.
• The build_package workflow is authoritative for same-run evidence. It downloads the generated binding and Linux payload, assembles a disposable package bundle, compiles a clean public consumer, and loads the bundled native library before publish dry-run or publication can be eligible.

Focused local commands:

flutter test -j 1 test/native_cache_manifest_cli_test.dart test/platform_release_proof_test.dart
flutter test -j 1 test/android_ssl_helper_test.dart test/android_ssl_helper_diagnostic_test.dart
flutter test -j 1 test/architecture_policy_ast_test.dart test/workflow_policy_graph_test.dart
flutter test -j 1 test/package_consumer_bundle_test.dart
flutter analyze

Set GIT2DART_FIXTURE_PACKAGE_ROOT only to an explicit expanded fixture package when running local consumer/native proof. CI does not use a global-cache or checkout fallback: its bundle inputs come from artifacts produced by that run.
