stripLow method
Removes characters with a numerical value less than 32 and 127.
If keepNewLines
is true, newline characters are preserved (\n and \r, hex 0xA and 0xD).
Implementation
String stripLow([bool keepNewLines = false]) {
final chars = keepNewLines == true
? '\x00-\x09\x0B\x0C\x0E-\x1F\x7F'
: '\x00-\x1F\x7F';
return blacklist(chars);
}
