void removePoolTransaction(String? bJJ, String? transactionId)

Removes a transaction from the transaction pool @param {string} bJJ - The account with which the transaction was originally made @param {string} transactionId - The transaction identifier to remove from the pool @returns {void}

Implementation

      ? chainIdTransactionPool[bJJ]
      : [];

  accountTransactionPool.removeWhere((transaction) =>
