Dart2Java dev compiler

The Dart2Java dev compiler is a transpiler from Dart to Java source. It is based on DDC and Kernel IR, and its main goal is to investigate which features of the Dart language make it particularly hard or easy for AOT compilation to a new language. Ideally, Dart2Java will enable interoperability between Dart and Java programs, and automatic translation of Dart programs to Java source.

Compiling the SDK

The easy way to build the SDK is to run the tool/build_sdk.sh script.

The script executes the following steps:

• Patch the SDK: tool/patch_sdk.sh
• Compile the SDK: dart2java --dart-sdk=gen/patched_sdk --output=gen/compiled_sdk --package-prefix=dart dart:_internal ...
• Compile the generated .java files with javac
• Archive the generated .class files with jar
