Dart Macros Project Abandoned: Focusing on Data Handling and Build Performance

The Dart team announced the cancellation of its long-running macros project due to high compile-time costs impacting developer experience, particularly hot reload. The team acknowledged insurmountable technical hurdles, deciding to prioritize improving data handling capabilities and build speeds over continuing to invest in macros. Future efforts will focus on better data serialization/deserialization support, enhancements to the `build_runner` tool, and the independent release of augmentations—a feature initially prototyped as part of the macros project—to improve developer workflow.
