* @assertion Object encode(Object value, {toEncodable(object)})
* Converts value to a JSON string.
* If value contains objects that are not directly encodable to a JSON string
* (a value that is not a number, boolean, string, null, list or a map with
* string keys), the toEncodable function is used to convert it to an object
* that must be directly encodable.
* If toEncodable is omitted, it defaults to calling .toJson() on the
* unencodable object.
* @description Checks that if a value is any other type than num, String, bool,
* Null, List, or Map, a "toJson()" method is invoked on the object and the
* result, which must be a directly serializable value, is serialized instead of
* the original value.
