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() => [
      'TerminalException: ${code.name}',
      message,
      if (paymentIntent != null) paymentIntent,
      if (apiError != null) apiError,
      if (stackTrace != null) stackTrace,
    ].join('\n');
