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() {
  final buffer = StringBuffer('BatteryStats(');
  buffer.write('gpsOn: ${gpsOnTimePercent.toStringAsFixed(1)}%, ');
  buffer.write('updates: $locationUpdatesCount, ');
  buffer.write('syncs: $syncRequestsCount, ');
  buffer.write('avgAccuracy: ${averageAccuracyMeters.toStringAsFixed(1)}m, ');
  buffer.write('duration: ${trackingDurationMinutes}min');
  if (estimatedDrainPerHour != null) {
    buffer.write(', drain: ${estimatedDrainPerHour!.toStringAsFixed(1)}%/hr');
  }
  buffer.write(')');
  return buffer.toString();
}
