toString method

  1. @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.


String toString() {
  // Figure out the longest path so we know how much to pad.
  var longest = traces
      .map((trace) => trace.frames
          .map((frame) => frame.location.length)
          .fold(0, math.max))
      .fold(0, math.max);

  // Don't call out to [Trace.toString] here because that doesn't ensure that
  // padding is consistent across all traces.
  return traces
      .map((trace) => trace.frames
          .map((frame) =>
              '${frame.location.padRight(longest)}  ${frame.member}\n')
