    required: bool = True,
    default: Any = None,

Bases: Field

Argument	Description
`required`	Whether the field is required. Defaults to `True`.
`default`	Default value for the field. Can be a static value or a callable. Defaults to `None`.
`schemes`	URL/URI scheme list to validate against. If not provided, the default list is ["http", "https"].
`pattern`	A regex pattern that the string must match. Defaults to `None`.
`one_of`	List of values that the field value must be one of. Defaults to `None`.
`messages`	Dictionary of error codes to custom error message templates. These override the default error messages for this specific field. Example: {"required": "This field cannot be empty"}.

Even if the format is valid, it cannot guarantee that the URL is real. The purpose of this function is to alert the user of a typing mistake.

Perform an UTS-46 normalization of the domain, which includes lowercasing (domain names are case-insensitive), NFC normalization, and converting all label separators (the period/full stop, fullwidth full stop, ideographic full stop, and halfwidth ideographic full stop) to basic periods.
