使用Dart将Uint8List转换为字符串 [英] Convert Uint8List to String with Dart

问题描述

cipher.process返回一个Uint8List，它是一个无符号整数(0-255)的列表.我需要将此Uint8List转换为可以轻松转换回同一Uint8List的字符串.

cipher.process returns an Uint8List which is a list of unsigned integers (0-255). I need to convert this Uint8List to a string that I can easily convert back to the same Uint8List.

    var cipherText = cipher.process( inputAsUint8List );        
    return ASCII.decode(cipherText);

ASCII.decode引发错误，因为某些整数大于127.

ASCII.decode throws an error since some of the integers are > 127.

推荐答案

我想应该这样做:

String s = new String.fromCharCodes(inputAsUint8List);
var outputAsUint8List = new Uint8List.fromList(s.codeUnits);
