Uri.http constructor Null safety

Creates a new http URI from authority, path and query.

Examples:

// http://example.org/path?q=dart.
Uri.http("example.org", "/path", { "q" : "dart" });

// http://user:pass@localhost:8080
Uri.http("user:pass@localhost:8080", "");

// http://example.org/a%20b
Uri.http("example.org", "a b");

// http://example.org/a%252F
Uri.http("example.org", "/a%2F");

The scheme is always set to http.

The userInfo, host and port components are set from the authority argument. If authority is null or empty, the created Uri has no authority, and isn't directly usable as an HTTP URL, which must have a non-empty host.

The path component is set from the unencodedPath argument. The path passed must not be encoded as this constructor encodes the path.

The query component is set from the optional queryParameters argument.
