A Dart SDK for building todo applications with Nostr protocol.

Example

void main() async {
  // Initialize in-memory database for example
  final db = await databaseFactoryMemory.openDatabase('example.db');

  // Initialize NDK
  final ndk = Ndk(
    NdkConfig(cache: MemCacheManager(), eventVerifier: Bip340EventVerifier()),
  );

  // Login with a private key (example - use secure storage in production)
  // This is just for demonstration
  ndk.accounts.loginPrivateKey(
    pubkey: "b8b7d8681855c33abac83c7f022058d74f2d66fdb5eff1e137d15efecc29a3e6",
    privkey: "1206809c7dce1ddf4915eb9a7388a001ca7f66395d4bb2c2a50335892fc2c2ce",
  );

  // Create TodoService instance - automatically starts listening to todo events
  final todoService = TodoService(ndk: ndk, db: db);

  // Example: Create a todo
  final todo = await todoService.createTodo(
    description: 'Buy groceries',
    encrypted: false,
  );
  print('Created todo: ${todo.description}');

  // Example: Switch to a different account
  ndk.accounts.logout();
  ndk.accounts.loginPrivateKey(
    pubkey: "different_pubkey_here",
    privkey: "different_privkey_here",
  );
  
  // IMPORTANT: Notify TodoService about auth state change
  todoService.onAuthStateChanged();
  
  // Now the service is listening to the new user's events
  
  // When done, clean up
  todoService.stopListening();
}
