Returns hex representation of bytes contained in this memo until null byte (0x00) is found.

MemoHash memo = MemoHash("4142434445");
memo.getHexValue(); // 4142434445000000000000000000000000000000000000000000000000000000
memo.getTrimmedHexValue(); // 4142434445
Implementation
String get trimmedHexValue => this.hexValue.split("00")[0];
