Can't login to GMail w/ valid credentials about imap_client

Hi, r'...' tells dart to treat the text as a regular expression. You can escape special characters with a backslash: 'xxxx\$xxxx'. Other than that I cannot see any apparent mistakes.

My understanding is that r is raw string. From https://www.learndartprogramming.com/fundamentals/strings-and-raw-strings-in-dart/
Maybe I'm confused, but I don't think so (at least, at this moment)

Defining raw Strings in Dart
What is a raw strings in Dart: In Dart programming language, raw strings are a type of strings where special characters such as \ do not get special treatment.

Raw strings are useful when you want to define a String that has a lot of special characters.

Wrong language, my bad - you are correct. Your code seems to be equal to the example which has been tested with gmail, so it should be alright...

I created a Google account with userid/password shown below. It still fails. You can try this code

import 'dart:io';

import 'package:imap_client/imap_client.dart';

Future<void> main() async {
  // print log, helpful for debugging
  printImapClientDebugLog();

  var client = ImapClient();
  // connect
  await client.connect('imap.gmail.com', 993, true);
  // authenticate
  final response = await client.authenticate(
      ImapPlainAuth('[email protected]', r'ujbzZ4uhmd'));

  print('reponse ok? ${response == ImapTaggedResponse.ok}');
  if (response != ImapTaggedResponse.ok) {
    exit(1);
  }
  // get folder
  var inbox = await client.getFolder('Inbox');
  // get "BODY" for message 1
  print(await inbox.fetch(['BODY'], messageIds: [1]));
  // get "BODYSTRUCTURE" for message 1
  print(await inbox.fetch(['BODYSTRUCTURE'], messageIds: [1]));
  // close connection
  await client.logout();
}```

Logs:

Did you enable imap in gmail's options? Other than that I really cannot see why this shouldn't work

[bartonhammond]

When I went to check the Google Settings, I was prompted with warning that a call from an unsecure app had been blocked because it didn't meet the standards Google has. It asked if the block was correct or if I were the person trying to access the account. Once I replied that I was blocked, it took me through these screens about reducing the security. Sorry I didn't get a picture of the first dialog.

So I updated

And now it works:
