generateBoilerplate method

void generateBoilerplate({ required String featureName, required String basePath, required String templateBasePath, required Context context, required bool overwrite, })

Renders all Mustache templates (model, entity, repository, datasource, usecase, bloc/event/state, or riverpod notifier) into the feature directory.

Each template receives a simple map to keep the generator decoupled from the Mustache engine.
