toString method

@override String toString([ String prefix = '' ])

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([String prefix = '']) {
  var buffer = StringBuffer();
  buffer.writeln('${prefix}Version: ${version}');
  buffer.writeln('${prefix}Serial Number: ${serialNumber}');
  buffer.writeln('${prefix}Signature Algorithm: ${signature}');
  buffer.writeln('${prefix}Issuer: ${issuer}');
  buffer.writeln('${prefix}Validity:');
  buffer.writeln(validity?.toString('$prefix\t') ?? '');
  buffer.writeln('${prefix}Subject: ${subject}');
  buffer.writeln('${prefix}Subject Public Key Info:');
  buffer.writeln(subjectPublicKeyInfo?.toString('${prefix}\t') ?? '');
  if (extensions != null && extensions!.isNotEmpty) {
    buffer.writeln('${prefix}X509v3 extensions:');
    for (var e in extensions!) {
      buffer.writeln(e.toString('${prefix}\t'));
    }
  }
  return buffer.toString();
