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() {
final parts = <String>[];
if (fg != null) parts.add('fg: $fg');
if (bg != null) parts.add('bg: $bg');
if (fgRgb != null) parts.add('fgRgb: $fgRgb');
if (bgRgb != null) parts.add('bgRgb: $bgRgb');
if (fgIndexed != null) parts.add('fgIndexed: $fgIndexed');
if (bgIndexed != null) parts.add('bgIndexed: $bgIndexed');
if (!addModifier.isEmpty) parts.add('+$addModifier');
if (!subModifier.isEmpty) parts.add('-$subModifier');
return 'Style(${parts.join(', ')})';
}
