convert method
inherited
Converts the String into a list of its code units.
If start
and end
are provided, only the substring
string.substring(start, end)
is used as input to the conversion.
Implementation
Uint8List convert(String string, [int start = 0, int end]) {
int stringLength = string.length;
RangeError.checkValidRange(start, end, stringLength);
if (end == null) end = stringLength;
int length = end - start;
var result = new Uint8List(length);
for (int i = 0; i < length; i++) {
var codeUnit = string.codeUnitAt(start + i);
if ((codeUnit & ~_subsetMask) != 0) {
throw new ArgumentError("String contains invalid characters.");
}
result[i] = codeUnit;
}
return result;
}
