toString method
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 'NERtcVideoLayerSendStats{layerType: $layerType, '
      'width: $width, height: $height, captureWidth: $captureWidth,'
      'captureHeight: $captureHeight, sendBitrate: $sendBitrate, '
      'encoderOutputFrameRate: $encoderOutputFrameRate, '
      'captureFrameRate: $captureFrameRate, targetBitrate: $targetBitrate, '
      'sentFrameRate: $sentFrameRate, encoderName: $encoderName,'
      'encoderBitrate: $encoderBitrate, renderFrameRate: $renderFrameRate'
      'dropBwStrategyEnabled:$dropBwStrategyEnabled}';
}
