flutter_gpu_shaders 0.5.1

Build tools for Flutter GPU shader bundles/libraries.

0.5.1

• Added a glesLanguageVersion option to buildShaderBundleJson (and shaderBundleImpellercArguments), forwarded to impellerc as --gles-language-version. Setting 300 emits #version 300 es OpenGL ES shaders, where explicit-LOD sampling and derivatives are core rather than extension-gated.
• findImpellerC now also probes the linux-arm64 and windows-arm64 engine artifact directories; the previous x64-only list failed on Linux arm64 hosts.

0.5.0

• Fixed dependency tracking that made the build hook re-run on every build. Manifest file entries are now resolved against the package root (matching how impellerc resolves them) instead of the manifest's directory, which had produced doubled, non-existent paths for manifests in a subdirectory.
• Generated shader sources written under the package's build/ directory are no longer declared as build dependencies; depending on a regenerated output made the hook perpetually out of date. Declare the real sources that produce them instead.
• Breaking: collectShaderBundleDependencies now requires a packageRoot argument (used to resolve manifest file paths). Most consumers use buildShaderBundleJson, whose signature is unchanged.

0.4.5

• Added optional Dart DataAssets registration for shader bundles via ShaderBundleAssetMode. The default remains legacy file output under build/shaderbundles/, while dataAssetsIfAvailable registers the generated .shaderbundle with the Flutter asset bundle when supported and falls back otherwise.
• buildShaderBundleJson now returns ShaderBundleBuildResult, including the legacy asset key and DataAsset/Flutter asset keys when a DataAsset is emitted.

0.4.4

• buildShaderBundleJson now consumes impellerc depfiles when the resolved compiler advertises --depfile support. This lets newer Flutter SDKs track transitive shader #include dependencies while preserving the existing manifest dependency scan for older impellerc builds that do not support the flag or do not emit a depfile in --shader-bundle mode.
• buildShaderBundleJson accepts an includeDirectories parameter: extra directories appended to impellerc's #include search path, after the manifest directory and the bundled shader_lib. This lets a build hook compile shaders that #include reusable GLSL shipped by another package, by resolving that package's shader directory and passing it through. Files resolved this way are not auto-declared as build dependencies; declare them via the build output if edits to them should retrigger the build.
• New shaderBundleImpellercArguments(...) helper returns the exact impellerc argument list, exposed for inspection from custom build hooks and tests.

0.4.3

• buildShaderBundleJson now declares the manifest and every shader source file it references as build-hook dependencies. The build system reruns the hook (and impellerc) whenever any of those inputs change, so editing a .frag no longer requires a manual clean. Transitive #includes aren't tracked yet because impellerc's --depfile switch is a no-op when --shader-bundle is in use; this is a known limitation pending an upstream fix.
• New collectShaderBundleDependencies(manifestUri, decodedManifest) helper returns the dependency set for inspection from custom build hooks and tests.

0.1.0

• Add buildShaderBundleJson build hook utility.
• Document usage instructions in the readme.

0.1.1

• Fix working directory for impellerc invocation.

0.1.2

• Fix SDK path resolution for puro users.

0.1.3

• Relax native_assets_cli dependency pin.

0.1.4

• Pin native_assets_cli to <0.9.0. (https://github.com/bdero/flutter_gpu_shaders/issues/3)

0.2.0

• Update to native_assets_cli 0.9.0. Breaking: BuildOutput is now BuildOutputBuilder

0.2.1

• Bump native_assets_cli to 0.10.0.

0.3.0

• Update to native_assets_cli to 0.13.0. (https://github.com/bdero/flutter_gpu_shaders/issues/6) Breaking: BuildConfig is now BuildInput

0.4.0

• Migrate from native_assets_cli (discontinued) to hooks 1.0. Build hook authors must now import 'package:hooks/hooks.dart'; instead of package:native_assets_cli/native_assets_cli.dart.
• Bump SDK constraint to ^3.7.0 (matches hooks 1.0 requirements).

0.4.2

• findImpellerC now also honors a runtime IMPELLERC environment variable in addition to the compile-time define. flutter_tools populates this for build hook subprocesses (https://github.com/flutter/flutter/pull/186300), including the --local-engine case where the locally built impellerc should be used in preference to the SDK cache. Compile-time define takes precedence; runtime env var is checked next; otherwise the existing SDK cache lookup runs.

0.4.1

• Documentation: update README.md and buildShaderBundleJson dartdoc to reflect the 0.4.0 migration (drop the obsolete flutter config --enable-native-assets step, swap the import, and rename buildConfig: → buildInput: to match the parameter name introduced in 0.3.0). No code changes.
