This package contains the basic protocol flows for Nostr as described in the NIP-01.
Features #
This package contains the basic protocol flows for Nostr as described in the NIP-01. This includes the creation of key pairs, event creation, event publishing, event requests, and event listening among others.
Usage #
import 'package:nip01/nip01.dart';
import 'package:dartstr_utils/dartstr_utils.dart';
final keyPair = KeyPair.generate();
print('privateKey: ${keyPair.privateKey}');
final nip01Repository = Nip01RepositoryImpl(
relayClientsManager: RelayClientsManagerImpl(['wss://example.relay.org']),
);
final partialEvent = Event(
pubkey: '981cc2078af05b62ee1f98cff325aac755bf5c5836a265c254447b5933c6223b',
createdAt: 1672175320,
kind: EventKind.textNote.value,
tags: [],
content: "This is an event.",
);
final signedEvent = partialEvent.sign(keyPair);
final isPublished = await nip01Repository.publishEvent(signedEvent);
if (!isPublished) {
throw Exception('Failed to publish event');
}
// Subscribe to events on the relay
final String subscriptionId = SecretGenerator.secretHex(
64,
); // SecretGenerator is part of the dartstr_utils package
final eventsStream = await nip01Repository.subscribeToEvents(
subscriptionId,
[
Filters(
authors: [keyPair.publicKey],
since: 1672175320,
),
],
);
eventsStream.listen((event) {
print('Received event: $event');
});
