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 String typeName = objectRuntimeType(this, 'TextSelection');
  if (!isValid) {
    return '$typeName.invalid';
  }
  return isCollapsed
    ? '$typeName.collapsed(offset: $baseOffset, affinity: $affinity, isDirectional: $isDirectional)'
    : '$typeName(baseOffset: $baseOffset, extentOffset: $extentOffset, isDirectional: $isDirectional)';
}
