@override String get stringValue

Canonical string representation of this item.

Implementation

@override
String get stringValue {
  if (value.isNaN) return 'NaN';
  if (value == double.infinity) return 'INF';
  if (value == double.negativeInfinity) return '-INF';
  if (value == 0.0) return value.isNegative ? '-0' : '0';
  var d = value;

        break;
      }
    }
