liquid_codegen 0.1.2

Optional YAML → typed LiquidEvent codegen for liquid_analytics. Generates sealed-class compatible event classes with no build_runner required.

example/main.dart

// Generate typed LiquidEvent classes from a YAML schema.
//
// Normally you would run the bundled CLI:
//
//   dart run liquid_codegen:generate --input events.yaml --output lib/events.dart
//
// This example calls the same library API directly.
