operator [] abstract method
- int index
The character (as a single-code-unit String) at the given index.
The returned string represents exactly one UTF-16 code unit, which may be half of a surrogate pair. A single member of a surrogate pair is an invalid UTF-16 string:
var clef = '\u{1D11E}';
// These represent invalid UTF-16 strings.
clef[0].codeUnits; // [0xD834]
clef[1].codeUnits; // [0xDD1E]
This method is equivalent to
String.fromCharCode(this.codeUnitAt(index)).
Implementation
String operator [](int index);
