toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  var l = (left is BinaryExpression &&
          (left as BinaryExpression).precedence < precedence)
      ? '($left)'
      : '$left';
  var r = (right is BinaryExpression &&
          (right as BinaryExpression).precedence < precedence)
      ? '($right)'
      : '$right';
  return '$l$operator$r';
}
