AsciiDecoder class final
Converts ASCII bytes to string.
Example:
const asciiDecoder = AsciiDecoder();
final asciiValues = [68, 97, 114, 116];
final result = asciiDecoder.convert(asciiValues);
print(result); // Dart
Throws a FormatException if bytes contains values that are not
in the range 0 .. 127, and allowInvalid is false (the default).
If allowInvalid is true, any byte outside the range 0..127 is replaced
by the Unicode replacement character, U+FFFD ('�').
Example with allowInvalid set to true:
const asciiDecoder = AsciiDecoder(allowInvalid: true);
final asciiValues = [68, 97, 114, 116, 20, 0xFF];
final result = asciiDecoder.convert(asciiValues);
print(result); // Dart �
print(result.codeUnits.last.toRadixString(16)); // fffd
