To Reproduce Steps to reproduce the behavior:

1. sign in with magic link
2. call the method supabase.auth.mfa.getAuthenticatorAssuranceLevel()

Expected behavior The method returns the assurance level.

Version (please complete the following information):

─ supabase_flutter 2.5.7
│   ├── supabase 2.2.3
│   │   ├── functions_client 2.2.0
│   │   ├── gotrue 2.8.2

Additional context The toList()of the piece of code throws the exception:

  final amr = (payload['amr'] as List)
        .map((e) => AMREntry.fromJson(Map.from(e)))
        .toList();

My amr payload is :

{
  "amr": [
    {
      "method": "magiclink",
      "timestamp": 1720269381
    }
  ]
}

    {

      "timestamp": 1725530782
    }

@dshukertjr Could you ask the auth team what possible values the method can be? Here's a long list, but I'm unsure if all of those can appear on the client.

[dshukertjr]

@Vinzent03 Auth tema confirmed that this list is all the possible values for AMRMethod. If you would like to create a PR to add all the missing ones, that would be awesome!
