toString method

@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.

Implementation

@override
String toString() {
  final parts = <String>[];

  if (fontFamily != null) parts.add("fontFamily: '$fontFamily'");
  if (fontSize != null) parts.add('fontSize: $fontSize');
  if (fontWeight != null) parts.add('fontWeight: $fontWeight');
  if (lineHeight != null) parts.add('height: $lineHeight');
  if (letterSpacing != null) parts.add('letterSpacing: $letterSpacing');

  if (parts.isEmpty) return 'const TextStyle()';

  return '''const TextStyle(
${parts.join(',\n  ')},
)''';
}
