generateFeature function

void generateFeature({ required String projectName, required String featureName, })

Generates a complete feature with clean architecture structure.

Auto-detects state management from .sm_cli_config. Creates Data, Domain, and Presentation layers.

Example:

cd my_app
sm make feature auth
