toString method
Converts bytes to a string by interpreting each byte as a character code.
Negative bytes are converted to their unsigned equivalents first.
Example:
final hello = Byte.fromString('Hello');
print(hello.toString()); // 'Hello'
final bytes = Byte.fromList([65, 66, 67]);
print(bytes.toString()); // 'ABC'
Implementation
@override
String toString() {
if (isEmpty) return '';
return String.fromCharCodes(toUnsignedList());
}
