buildHTML method

@override String buildHTML({ bool withIndent = false, String parentIndent = '', String indent = ' ', bool disableIndent = false, bool xhtml = false, bool resolveDSX = false, bool buildTemplates = false, DOMNode? parentNode, DOMNode? previousNode, DOMContext? domContext, })

Generates a HTML from this node tree.

withIndent If true will generate a indented HTML.
