eigen_codegen #

Development-only code generation for EigenInteractive game contracts.

Add eigen_codegen as a development dependency, then generate the immutable Dart payload types and the two version-specific bases used by your game: a <Game>V<N>RulesBase carrying the wire payload codecs, and a <Game>V<N>LocalRulesBase carrying the state codec offline play additionally needs:

dart run eigen_codegen:generate_payloads \
  --contract ../server/game-contract.json \
  --output lib/game/generated/payloads.dart \
  --fixtures-output test/fixtures

Use the same command with --check in CI to reject generated drift. Runtime Flutter APIs live in eigen_flutter.
