I am trying to override a backend widget partial using a plugin. I want the 'Manage widgets' button of the dashboard to only be visible from administrators belonging to a certain group. I didn't find any events to hook onto in order to change the twig template or a way to monkey-patch the widget's render method. Is it possible?

I finally found a solution.

Short version:

Add the following in the boot() method of your plugin

ReportContainer::extend(function ($widget) {
    $widget->addViewPath(plugins_path().'/myVendor/myPlugin/widgets/reportcontainer/partials/');
});

Explanation

The widget responsible for hosting the dashboard report widgets is Backend\Widgets\ReportContainer. It extends WidgetBase which in turn extends Extendable. Using the extend() method of Extendable you can extend the classes' constructor, calling class methods when an object of that class is instantiated. WidgetBase also has the trait ViewMaker which adds methods for handling views. We can make use of that by calling the addViewPath method of ViewMaker to include our path in the view path locations. That way, we can override a template by creating a file of the same name in our new path.

The original issue has been solved with the recent addition of the backend.manage_default_dashboard permission
