trait MessagesActionBuilder extends ActionBuilder[MessagesRequest, AnyContent]
This trait is an ActionBuilder that provides a MessagesRequest to the block:
class MyController @Inject()( messagesAction: MessagesActionBuilder, cc: ControllerComponents ) extends AbstractController(cc) { def index = messagesAction { implicit request: MessagesRequest[AnyContent] => Ok(views.html.formTemplate(form)) // twirl template with form builders } }
This is useful when you don't want to have to add play.api.i18n.I18nSupport to a controller for form processing.

Invoke the block.
Invoke the block. This is the main method that an ActionBuilder has to implement, at this stage it can wrap it in any other actions, modify the request object or potentially use a different class to represent the request.
