isByteLength function Null safety
- String str,
- {dynamic min = 0,
- dynamic max}
check if the string's length (in bytes) falls in a range.
Implementation
bool isByteLength(String str, {min = 0, max}) {
var len = Uri.encodeFull(str).split(r'/%..|./').length - 1;
return len >= min && (max == null || len <= max);
}
