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;
