After installing plugin, create any domain class in your application, if there isn't any.
Lets say you have created MyDomain.groovy in com.foo package. Now, execute below grails command to create entire angular structure based on your domain.
grails create-ng-skeleton _domain-class-name-fully-qualified_
For our example, you can execute command as:
grails create-ng-skeleton com.foo.MyDomain
It will create following files into your grails application:
Templates will include css classes of Materialize css framework.
Few other commands are also available by this plugin:
grails create-ng-view _domain-class-name-fully-qualified_
It will create only template files under grails-app/assets/javascripts/_package_/_domain_/templates folder structure.
grails create-angular-controller _domain-class-name-fully-qualified_
It will create _domain_Controller.js file under grails-app/assets/javascripts/_package_/_domain_/controllers folder structure.
grails create-angular-service _domain-class-name-fully-qualified_
It will create _domain_DataFactoryService.js file under grails-app/assets/javascripts/_package_/_domain_/services folder structure.
