| /** |
| * @assertion An entry element (the base case in maps): |
| * |
| * It is a compile-time error if the key and value expressions are not constant |
| * expressions. |
| * |
| * As is already the case in Dart, it is a compile-time error if the key is an |
| * instance of a class that implements the operator == unless the key is a |
| * Boolean, string, an integer, a literal symbol or the result of invoking a |
| * constant constructor of class Symbol. It is a compile-time error if the type |
| * arguments of a constant map literal include a type parameter. |
| * |
| * The expansion is the entry formed by the key and value expression values. |
| * |
| * @description Checks that it is a compile-time error if the key or value |
| * expressions are not constant expressions. |
