length property
int
length
The length of the string.
Returns the number of UTF-16 code units in this string. The number of runes might be fewer, if the string contains characters outside the Basic Multilingual Plane (plane 0):
'Dart'.length; // 4 'Dart'.runes.length; // 4
var clef = '\u{1D11E}'; clef.length; // 2 clef.runes.length; // 1
Implementation
int get length {
if (this == null) {
return 0;
}
return this!.length;
}
