-   * Returns a new `Uri` based on this one, but with some parts replaced.
-   *
-   * This method takes the same parameters as the [new Uri] constructor,
-   * and they have the same meaning.
-   *
-   * At most one of [path] and [pathSegments] must be provided.
-   * Likewise, at most one of [query] and [queryParameters] must be provided.
-   *
-   * Each part that is not provided will default to the corresponding
-   * value from this `Uri` instead.
-   *
-   * This method is different from [Uri.resolve] which overrides in a
-   * hierarchial manner,
-   * and can instead replace each part of a `Uri` individually.
-   *
-   * Example:
-   *
-   *     Uri uri1 = Uri.parse("a://b@c:4/d/e?f#g");
-   *     Uri uri2 = uri1.replace(scheme: "A", path: "D/E/E", fragment: "G");
-   *     print(uri2);  // prints "A://b@c:4/D/E/E/?f#G"
-   *
-   * This method acts similarly to using the `new Uri` constructor with
-   * some of the arguments taken from this `Uri` . Example:
-   *
-   *     Uri uri3 = new Uri(
-   *         scheme: "A",
-   *         userInfo: uri1.userInfo,
-   *         host: uri1.host,
-   *         port: uri1.port,
-   *         path: "D/E/E",
-   *         query: uri1.query,
-   *         fragment: "G");
-   *     print(uri3);  // prints "A://b@c:4/D/E/E/?f#G"
-   *     print(uri2 == uri3);  // prints true.
-   *
-   * Using this method can be seen as a shorthand for the `Uri` constructor
-   * call above, but may also be slightly faster because the parts taken
-   * from this `Uri` need not be checked for validity again.
