A Getter is a plugin primitive used to share a value between other plugins. The shared value is a single field of the plugin-based component's state.
Commonly, a getter is used to access a value associated with it in the markup of another plugin. For this, use the TemplateConnector primitive.
A getter can hold an array or function as well as values like strings, numbers etc.
A value defined by a Getter is a part of a plugin's public API which means other plugins can access and change this value.
In the example above, a getter with the same name can override the current getter's value. You can also compute a getter's value regarding other getters and local variables.
