nostr_dart 0.6.4

A Nostr protocol client API for building censorship-resistant social network applications in Dart/Flutter.

0.1.0

• Initial version.

0.1.1

• Fixed package import documentation.

0.2.0

• Added support for NIP-02: Contact List and Petnames.

0.3.0

• Reworked Contact & Nostr class constructors to make instantiating these classes more terse.
• Added a method to publish arbitrary events [Nostr.sendEvent].

0.4.0

• Refactored relay management and subscription requests into a RelayPool class. This changes the interfaces for adding/removing relays and subscribing/unsubscribing to events.
• Nostr.pool.add only sends existing subscriptions to a newly added relay if its autoSubscribe parameter is true.
• Nostr.pool.add allows read/write attributes to be configured for relays with its access parameter.
• Received events are now accessed via a listener callback provided to Nostr.pool.subscribe. This allows different subscriptions to route events to different event listeners.
• Nostr.sendTextNote, Nostr.sendMetaData, Nostr.recommendServer, Nostr.sendContactList, Nostr.pool.subscribe, are no longer asynchronous operations. nostr_dart now maintains an asynchronous job queue for each connected relay to sequence relay communications.

0.4.1

• Fixed incorrectly formatted subscription requests.

0.5.0

• Shortened the length of randomly assigned Subscription IDs to an 8-byte hexadecimal string. Some relays were rejecting a 32-byte hexadecimal.
• Nostr.pool.subscribe is now an asynchronous operation returning a Future that completes when all expected end-of-stored events notices have been received.

0.6.0

• Added support for NIP-11: Relay Information Document. This includes a breaking API change to Nostr.pool.add which now takes a Relay object instead of a URL string and access read/write configuration.
• Added Nostr.pool.info to get relay information documents. This interface is likely to change.
• Added an automatic check for NIP-15 and NIP-20 support before connecting to a relay. Relays that don't support these protocol features will be rejected.
• Added Nostr.pool.isConnected to get relay connection status. This interface is likely to change.

0.6.1

• Fixed subscription requests timing out prematurely.

0.6.2

• Fixed subscription requests timing out after a previous call to Nostr.pool.unsubscribe.

0.6.3

• Received events that fail validation checks are discarded without throwing an exception to improve performance.

0.6.4

• Added an option to the Nostr constructor to disable signature verification as events are received. This is a temporary work-around for inadequate signature verification performance. The default remains for signature verification to be performed. When disabled, the signatures of individual events can still be verified using Event.isSigned.
