lookup static method Null safety

Future<List<InternetAddress>> lookup(
  1. String host,
  2. {InternetAddressType type = InternetAddressType.any}
)

Looks up the addresses of a host.

If type is InternetAddressType.any, it will lookup both IP version 4 (IPv4) and IP version 6 (IPv6) addresses. If type is either InternetAddressType.IPv4 or InternetAddressType.IPv6 it will only lookup addresses of the specified type. The order of the list can, and most likely will, change over time.

Implementation

external static Future<List<InternetAddress>> lookup(String host,
    {InternetAddressType type = InternetAddressType.any});
