+     * `type(contractName).creationCode`.
+     *
+     * Requirements:
+     * - `bytecode` must not be empty.
+     * - `salt` must have not been used for `bytecode` already.
+     * - the factory must have a balance of at least `value`.
+     * - if `value` is non-zero, `bytecode` must have a `payable` constructor.
