signOutUser static method
Signs out a user from the server and deletes all authentication keys. This means that the user will be signed out from all connected devices.
Implementation
static Future<void> signOutUser(Session session, {int? userId}) async {
userId ??= (await session.authenticated)?.userId;
if (userId == null) return;
await session.db
.deleteWhere<AuthKey>(where: AuthKey.t.userId.equals(userId));
await session.messages
.authenticationRevoked(userId, RevokedAuthenticationUser());
session.updateAuthenticated(null);
}
