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() {
  var out = StringBuffer()..write(context);
  if (locator is By) {
    if (index == null) {
      out.write('.findElement(');
    } else {
      out.write('.findElements(');
    }
    out
      ..write(locator)
      ..write(')');
  } else {
    out
      ..write('.')
      ..write(locator);
  }
  if (index != null) {
    out
      ..write('[')
      ..write(index)
      ..write(']');
  }
  return out.toString();
}
