data: {\n\t * requiredRole: 'foo'\n\t * } \n\t *\n\t * @param {object=} stateConfig.params\n\t * \n\t *\n\t * A map which optionally configures parameters declared in the `url`, or\n\t * defines additional non-url parameters.

This implicitly sets this parameter as optional.\n\t *\n\t * When UI-Router routes to a state and no value is\n\t * specified for this parameter in the URL or transition, the\n\t * default value will be used instead. If `value` is a function,\n\t * it will be injected and invoked, and the return value used.\n\t *\n\t * *Note*: `undefined` is treated as \"no default value\" while `null`\n\t * is treated as \"the default value is `null`\".\n\t *\n\t * *Shorthand*: If you only need to configure the default value of the\n\t * parameter, you may use a shorthand syntax. In the **`params`**\n\t * map, instead mapping the param name to a full parameter configuration\n\t * object, simply set map it to the default parameter value, e.g.:\n\t *\n\t * // define a parameter's default value\n\t * params: {\n\t * param1: { value: \"defaultValue\" }\n\t * }\n\t * // shorthand default values\n\t * params: {\n\t * param1: \"defaultValue\",\n\t * param2: \"param2Default\"\n\t * }\n\t *\n\t * - ** array ** - {boolean=}: *(default: false)* If true, the param value will be\n\t * treated as an array of values. If you specified a Type, the value will be\n\t * treated as an array of the specified Type. Note: query parameter values\n\t * default to a special `\"auto\"` mode.\n\t *\n\t * For query parameters in `\"auto\"` mode, if multiple values for a single parameter\n\t * are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values\n\t * are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`). However, if\n\t * only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single\n\t * value (e.g.: `{ foo: '1' }`).\n\t *\n\t * params: {\n\t * param1: { array: true }\n\t * }\n\t *\n\t * - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when\n\t * the current parameter value is the same as the default value. If `squash` is not set, it uses the\n\t * configured default squash policy.\n\t * (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})\n\t *\n\t * There are three squash settings:\n\t *\n\t * - false: The parameter's default value is not squashed. It is encoded and included in the URL\n\t * - true: The parameter's default value is omitted from the URL. If the parameter is preceeded and followed\n\t * by slashes in the state's `url` declaration, then one of those slashes are omitted.\n\t * This can allow for cleaner looking URLs.\n\t * - `\"params: {\n\t * param1: {\n\t * value: \"defaultId\",\n\t * squash: true\n\t * } }\n\t * // squash \"defaultValue\" to \"~\"\n\t * params: {\n\t * param1: {\n\t * value: \"defaultValue\",\n\t * squash: \"~\"\n\t * } }\n\t * \n\t *\n\t *\n\t * @example\n\t * \n\t * // Some state name examples\n\t *\n\t * // stateName can be a single top-level name (must be unique).\n\t * $stateProvider.state(\"home\", {});\n\t *\n\t * // Or it can be a nested state name.

The first\n\t * ui-sref-active found at the same level or above the ui-sref will be used.\n\t *\n\t * Will activate when the ui-sref's target state or any child state is active. If you\n\t * need to activate only when the ui-sref target state is active and *not* any of\n\t * it's children, then you will use\n\t * {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}\n\t *\n\t * @example\n\t * Given the following template:\n\t *
