Event.deserialize constructor

Event.deserialize(List input, { bool verify = true, })

Deserializes an event from a wire-format representation.

input should be a list containing either two or three elements. If it contains two elements, the second element should be a map representing the event. If it contains three elements, the second element should be a string representing the subscriptionId, and the third element should be a map representing the event.

Implementation

factory Event.deserialize(List input, {bool verify = true}) {
  var json = <String, dynamic>{};
  String? subscriptionId;
  if (input.length == 2) {
    json = input[1] as Map<String, dynamic>;
  } else if (input.length == 3) {
    json = input[2] as Map<String, dynamic>;
    subscriptionId = input[1] as String;
  } else {
    throw Exception('invalid input');
  }

  final tags = (json['tags'] as List<dynamic>)
      .map((e) => (e as List<dynamic>).map((e) => e as String).toList())
      .toList();

  return Event(
    id: json['id'] as String,
    pubkey: json['pubkey'] as String,
    created_at: json['created_at'] as int,
    kind: json['kind'] as int,
    tags: tags,
    content: json['content'] as String,
    sig: json['sig'] as String,
    subscriptionId: subscriptionId,
    verify: verify,
  );
}
