at_auth_io library

The dart:io half of at_auth: everything that needs a filesystem, a raw socket, or the dart:io HTTP stack.

package:at_auth/at_auth.dart holds the parts that do not — key material, the stores' interfaces, the auth and enrollment flows — so that a client compiled to WASM can authenticate. Anything a browser cannot do lives here instead, and importing this barrel is the statement that you are on a platform that can.

A dart:io program typically wants both of these, and neither is applied for you:

import 'package:at_auth/at_auth.dart';
import 'package:at_auth/at_auth_io.dart';
import 'package:at_lookup/at_lookup_io.dart';

retrofitSerializer = fileRetrofitSerializer;      // lock the keyfile
final atLookUp = secureSocketLookUps()(
    atSign: atSign, rootDomain: rootDomain, authenticator: null);
final enrollmentId = await activateAtSign(
    atSign: atSign,
    cramSecret: secret,
    keys: FileAtKeysIo(),                         // write keys to disk
    signingAlgo: SigningAlgoType.rsa2048,
    atLookUp: atLookUp,
    awaitProvisioning: true);
await atLookUp.close();

Each has a working default without this barrel — no serialiser and no keyfile — so a WASM build needs neither, and a dart:io build opts in to the behaviour it wants.
