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 '${objectRuntimeType(this, 'VideoPlayerValue')}('
      'duration: $duration, '
      'size: $size, '
      'position: $position, '
      'caption: $caption, '
      'captionOffset: $captionOffset, '
      'buffered: [${buffered.join(', ')}], '
      'isInitialized: $isInitialized, '
      'isPlaying: $isPlaying, '
      'isLooping: $isLooping, '
      'isBuffering: $isBuffering, '
      'volume: $volume, '
      'playbackSpeed: $playbackSpeed, '
      'errorDescription: $errorDescription, '
      'isCompleted: $isCompleted),';
}
