meta-dart

Yocto Layer for Google Dart CLI/Service projects.

It's based on the meta-flutter layer (author Joel Winarske) and J-P Nurmi's research on cross-compiling.

If you like this layer, help us get the Dart compiler to natively support cross-compilation, please thumbs up the following issue on GitHub! 👍 Allow AOT executables to be cross-compiled

Layers dependencies

• meta-clang

Recipes

• dart3-sdk
  • Compiles the Dart SDK for the target and installs this SDK on the target. The default installation directory is /opt/dart3-sdk.
• dart3-sdk-native
  • Compiles the Dart SDK for the Host to cross-compile your Dart project. You don't need to use it directly, dart3-app.bbclas will do it for you automatically.
• dart3-bin-sdk
  • Installs the offical Google binary ARM distribution on the target. The default installation directory is /opt/dart3-bin-sdk.
• cpumodel
  • Example project to create a package from a Dart project. You can create your own recipe based on this.

Usage

There are two possible use cases:

• If you only want to have SDK available on the target, add the dart3-bin-sdk package to the image installation list.

• To create a package from your Dart project, use the example project to create your own recipe. The example recipe can be found in the recipes-support/cpumodel directory

  • In this case if you also want the SDK to be available on the target (not required to install and run your package on the target), add the dart3-sdk package to the image installation list.

SDK version locking

The version of the SDK is based on the value of DART3_SDK_VERSION. The default value of DART3_SDK_VERSION is set in conf/include/dart3-sdk-version.inc. You can override DART3_SDK_VERSION in local.conf to choose a different SDK version:

DART3_SDK_VERSION = "3.1.5"

If you use the dart3-bin-sdk recipe, you must also provide the hashes of the binary archives:

DART3_BIN_SDK_X64_SHA256SUM = "4342ba274a4e9f8057079cf9de43b1c7bdb002016ad538313e8ebe942b61bba8"
DART3_BIN_SDK_ARM64_SHA256SUM = "0f0e19c276c99fa3efd6428ea4bef1502f742f2a1f9772959637eec775c10ba"

General

Only x64 host and aarch64 target architectures are supported.
