codeUnits gets you a List<int>
Uint8List.fromList(...) converts List<int> to Uint8List
String.fromCharCodes(...) converts List<int> orUint8ListtoString`


codeUnits


List<int>


Uint8List.fromList(...)


List<int>


Uint8List


String.fromCharCodes(...)


List<int> or


to


List<int> list = 'xxx'.codeUnits;
Uint8List bytes = Uint8List.fromList(list);
String string = String.fromCharCodes(bytes);
