HtmlEscapeMode class Null safety

HTML escape modes.

Allows specifying a mode for HTML escaping that depend on the context where the escaped result is going to be used. The relevant contexts are:

  • as text content of an HTML element.
  • as value of a (single- or double-) quoted attribute value.

All modes require escaping of & (ampersand) characters, and may enable escaping of more characters.

Custom escape modes can be created using the HtmlEscapeMode.HtmlEscapeMode constructor.
