toString method

  1. @override
String toString()
override

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() {
  // Compact JSON-ish form — safe for logging and matches the text
  // syntax accepted by [parseVectorText].
  final sb = StringBuffer('[');
  for (var i = 0; i < values.length; i++) {
    if (i != 0) sb.write(',');
    final v = values[i];
    // Prefer int-form for integral f32 values to keep output tidy.
    if (v.isFinite && v == v.truncateToDouble()) {
      sb.write(v.toInt().toString());
    } else {
      sb.write(v.toString());
    }
  }
  sb.write(']');
  return sb.toString();
}
