Dart macros offer a powerful alternative to build_runner for Flutter and Dart developers. They enable code generation directly at compile time, eliminating the need for separate build steps. Macros lead to faster builds, reduced boilerplate, and enhanced code consistency. They are currently available in the beta and main channels, with stable release expected in 2024. Macros support various uses, including creating custom annotations and implementing functions like toString. However, they require careful implementation to avoid complexity and hidden behaviors.
