cssExpression property

  1. @override
String? cssExpression

Returns the expression part of a CSS declaration. Declaration is:

property:expression;

E.g., if property is color then expression could be rgba(255,255,0) the CSS declaration would be 'color:rgba(255,255,0);'.

then _cssExpression would return 'rgba(255,255,0)'. See www.w3.org/TR/CSS21/grammar.html

Implementation

@override
String? get cssExpression {
  // TODO(terry): TBD
  return null;
}
