Package doesn't work with when Composer dependencies loaded before Wordpress

[chrisgherbert]

I'm using Bedrock to manage Wordpress and plugins using Composer. It looks like wp-admin-notification assumes that WordPress will be loaded before Composer dependencies:

PHP Fatal error:  Uncaught Error: Call to undefined function add_action() in /web/myproject.com/vendor/askupa-software/wp-admin-notification/bootstrap.php:39

I'm not familiar with Bedrock, but usually you would use wp-admin-notification as part of a plugin or a theme, which are loaded after WordPress core.

In a Bedrock environment, how can you tell when the WordPress core has been loaded?
