With this parameter you can explicitly identify classes to be documented, while keeping in the documentation some of the fields and methods defined in the classes to be excluded.

The tags specified in this parameter are treated as follows.

A class is included in the documentation only when it has one of the specified tags.

Each inheritable member of any excluded class, which has subclasses to be documented, will be shown as if it belongs to those of them that are the nearest descendants of the member's original class.
When you specify this parameter, the criteria above are only necessary for a class or member to be actually included in the documentation scope. However, they do not guarantee it. Using other include/exclude parameters, you can limit the documentation scope even further!
The multiple exclude-tag names must be separated with new lines ('\n'), semicolons (';') or colons (':'). For example:

@api
@include
