Data length for AES in binary data AES encryption/decryption example

[asavchuk]

Error for example of binary data AES encryption/decryption:

      Uint8List key = Uint8List.fromList(
          [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]);
      Uint8List iv = Uint8List.fromList(
          [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]);
    
      var crypt = AesCrypt('my cool password');
      crypt.aesSetParams(key, iv, AesMode.cbc);
    
      Uint8List srcData = Uint8List.fromList([1, 2, 3, 4, 5]);
    
      Uint8List encryptedData = crypt.aesEncrypt(srcData); // error on this line
      Uint8List decryptedData = crypt.aesDecrypt(encryptedData);
