In your controller, you can (or better: must) specify which menu item should be highlights, i.e. which menu item the controller (or the rendered action) belongs to. You can find several examples if you check the existing controllers in app/controllers and theior calls to the menu_item method towards the top.

In your case, you likely want to add something like menu_item :my_plugin to your DashboardController class so that it read similar to

class DashboardController < ApplicationController
  menu_item :my_plugin

  def index
    # ...
  end

  # ...
end

In your controller, you can (or better: must) specify which menu item [...]

FWIW and for future reference: additionally, declaring the menu_item in a controller is mandatory only in specific or non-conventional cases as documented for Redmine::MenuManager::MenuController::ClassMethods#menu_item in source:/trunk/lib/redmine/menu_manager.rb@22495#L38:

        # Set the menu item name for a controller or specific actions
        # Examples:
        #   * menu_item :tickets # => sets the menu name to :tickets for the whole controller
        #   * menu_item :tickets, :only => :list # => sets the menu name to :tickets for the 'list' action only
        #   * menu_item :tickets, :only => [:list, :show] # => sets the menu name to :tickets for 2 actions only
        #
        # The default menu item name for a controller is controller_name by default
        # Eg. the default menu item name for ProjectsController is :projects
