SassCalculation class final

A SassScript calculation.

Although calculations can in principle have any name or any number of arguments, this class only exposes the specific calculations that are supported by the Sass spec. This ensures that all calculations that the user works with are always fully simplified.

Available on Value, provided by the SassApiValue extension

Parses this as a compound selector, in the same manner as the selector-parse() function.
assertFunction([String? name]) → SassFunction
Throws a SassScriptException if this isn't a function reference.
inherited
assertMap([String? name]) → SassMap
Throws a SassScriptException if this isn't a map.
inherited
assertMixin([String? name]) → SassMixin
Throws a SassScriptException if this isn't a mixin reference.
inherited
assertNumber([String? name]) → SassNumber
Throws a SassScriptException if this isn't a number.
inherited
assertSelector({String? name, bool allowParent = false}) → SelectorList

Available on Value, provided by the SassApiValue extension

Parses this as a selector list, in the same manner as the selector-parse() function.
assertSimpleSelector({String? name, bool allowParent = false}) → SimpleSelector

Available on Value, provided by the SassApiValue extension

Parses this as a simple selector, in the same manner as the selector-parse() function.
assertString([String? name]) → SassString
Throws a SassScriptException if this isn't a string.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
sassIndexToListIndex(Value sassIndex, [String? name]) → int
Converts sassIndex into a Dart-style index into the list returned by asList.
inherited
toCssString({bool quote = true}) → String
Returns a valid CSS representation of this.
inherited
toString() → String
Returns a string representation of this.
inherited
tryMap() → SassMap?
Returns this as a SassMap if it is one (including empty lists, which count as empty maps) or returns null if it's not.
inherited
withListContents(Iterable<Value> contents, {ListSeparator? separator, bool? brackets}) → SassList
Returns a new list containing contents that defaults to this value's separator and brackets.
