TextSyntax constructor
Create a new TextSyntax which matches text on pattern.
If sub is passed, it is used as a simple replacement for pattern. If
startCharacter is passed, it is used as a pre-matching check which is
faster than matching against pattern.
Implementation
TextSyntax(
super.pattern, {
String sub = '',
super.startCharacter,
super.caseSensitive,
}) : substitute = sub;
