toString method Null safety

  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() {
  return '$runtimeType(buildDuration: ${_formatMS(buildDuration)}, '
      'rasterDuration: ${_formatMS(rasterDuration)}, '
      'vsyncOverhead: ${_formatMS(vsyncOverhead)}, '
      'totalSpan: ${_formatMS(totalSpan)}, '
      'layerCacheCount: $layerCacheCount, '
      'layerCacheBytes: $layerCacheBytes, '
      'pictureCacheCount: $pictureCacheCount, '
      'pictureCacheBytes: $pictureCacheBytes, '
      'frameNumber: ${_data.last})';
}
