I am studying/developing a module for Magento 2.
I created an observer for a specific event and now I'd like to collect some data such as Customer information and Product information. I know I can use the magic metods
get*Something* to navigate through the $data array and get specific values but how do I know what values are stored in the array? Is there a resource/documentation that lists at least the default parameters? I know it contains a lot of custom parameters from the different modules.
