Event class

Represents an event, which is the only object type in the system.

An event has the following properties:

  • id: A 32-byte hex-encoded sha256 hash of the serialized event data.
  • pubkey: A 32-byte hex-encoded public key of the event creator.
  • created_at: A unix timestamp in seconds indicating when the event was created.
  • kind: An integer representing the kind of the event.
  • tags: A list of lists representing tags of the event. Each tag list has three elements:
    1. The type of the tag (either "e" or "p").
    2. A 32-byte hex-encoded ID of another event (for type "e") or a 32-byte hex-encoded key (for type "p").
    3. A recommended relay URL.
  • content: An arbitrary string representing the content of the event.
  • sig: A 64-byte signature of the sha256 hash of the serialized event data, which is the same as the id field.

Additionally, an event may have a subscriptionId property, which is a random string used to represent a subscription.

Constructors

Event({required int kind, required List<List<String>> tags, required String content, required int created_at, String id = '', String sig = '', String pubkey = '', String? subscriptionId, bool verify = true})
Creates a new instance of the Event class.
Event.deserialize(List input, {bool verify = true})
Deserializes an event from a wire-format representation.
