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 represetion.

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() {
  return '$User('
      'displayName: $displayName, '
      'email: $email, '
      'emailVerified: $emailVerified, '
      'isAnonymous: $isAnonymous, '
      'metadata: $metadata, '
      'phoneNumber: $phoneNumber, '
      'photoURL: $photoURL, '
      'providerData, $providerData, '
      'refreshToken: $refreshToken, '
      'tenantId: $tenantId, '
      'uid: $uid)';
}
