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() {
  final List<String> description = <String>[
    'begin: $begin',
    'end: $end',
    'colors: $colors',
    if (stops != null) 'stops: $stops',
    'tileMode: $tileMode',
    if (transform != null) 'transform: $transform',
  ];

  return '${objectRuntimeType(this, 'LinearGradient')}(${description.join(', ')})';
}
