isAssociativeOperator property Null safety
true if this type of token represents an associative operator. An
associative operator is an operator for which the following equality is
(a * b) * c == a * (b * c). In other words, if the result of
applying the operator to multiple operands does not depend on the order in
which those applications occur.
Note: This method considers the logical-and and logical-or operators to be associative, even though the order in which the application of those operators can have an effect because evaluation of the right-hand operand is conditional.
