rfw_gen_builder

build_runner code generator for rfw_gen. Converts @RfwWidget-annotated Flutter functions to RFW (Remote Flutter Widgets) format.

Installation

Add to your pubspec.yaml:

dependencies:
  rfw_gen: ^0.4.0

dev_dependencies:
  rfw_gen_builder: ^0.4.0
  build_runner: ^2.4.0

Usage

  1. Annotate your widget functions with @RfwWidget:
import 'package:rfw_gen/rfw_gen.dart';

@RfwWidget('myWidget')
Widget buildMyWidget() {
  return Text('Hello');
}
  1. Run the generator:
dart run build_runner build

This generates:

  • .rfwtxt — human-readable RFW text
  • .rfw — binary format for production
  • .rfw_library.dart — LocalWidgetBuilder map for custom widgets
  • .rfw_meta.json — widget metadata for MCP/tooling
