| <p>A numeric identifier for the enumerated value.</p> | |
| <p>The values of a single enumeration are numbered | |
| consecutively from zero to one less than the | |
| number of values. | |
| This is also the index of the value in the | |
| enumerated type's static <code>values</code> list.</p> | |
| ## Implementation | |
| ```dart | |
| int get index; | |
| ``` | |
