findProgramAddress static method

(SolAddress, int) findProgramAddress({ required List<List<int>> seeds, required SolAddress programId, })

Converts a Solana value to lamports.

Implementation

  required SolAddress programId,

      throw const SolanaPluginException('Max seed length exceeded');
    }
    seedBytes = [...seedBytes, ...i];
  }
  while (nonce != 0) {
    try {
      final List<int> seedsWithNonce = [...seedBytes, nonce];

        seedBytes: seedsWithNonce,
        programId: programId,

    } catch (e) {
      nonce--;
      continue;
    }
  }
