Latin1Decoder class Null safety

This class converts Latin-1 bytes (lists of unsigned 8-bit integers) to a string.

Example:

final latin1Decoder = latin1.decoder;

const encodedBytes = [224, 225, 226, 227, 228, 229];
final decoded = latin1Decoder.convert(encodedBytes);
print(decoded); // àáâãäå

// Hexadecimal values as source
const hexBytes = [0xe0, 0xe1, 0xe2, 0xe3, 0xe4, 0xe5];
final decodedHexBytes = latin1Decoder.convert(hexBytes);
print(decodedHexBytes); // àáâãäå

Throws a FormatException if the encoded input contains values that are not in the range 0 .. 255 and allowInvalid is false ( the default ).

If allowInvalid is true, invalid bytes are converted to Unicode Replacement character U+FFFD (�).

Example with allowInvalid set to true:

const latin1Decoder = Latin1Decoder(allowInvalid: true);
const encodedBytes = [300];
final decoded = latin1Decoder.convert(encodedBytes);
print(decoded); // �
