Here is a fix:

final primaryKeys = (json['columns'] as List)
        .where((e) => (e['flags'] as List?)?.contains('key') == true)
        .map((e) => e['name'] as String)
        .toList();

@dshukertjr what do you think?

[offline-first]

The error is not in supabase-flutter but in supabase-dart...

[dshukertjr]

Sorry for the late reply!

@offline-first Yup, your fix looks amazing! Would you like to open a PR this repo?

[dshukertjr]

@offline-first BTW, I wonder why e['flags'] was null in your case. Would you be able to share the scheme of your messages table?

@dshukertjr PR is on the way

create table public.messages (
  id            bigint generated by default as identity primary key,
  inserted_at   timestamp with time zone default timezone('utc'::text, now()) not null,
  message       text,
  user_id       uuid references public.users not null,
  channel_id    bigint references public.channels on delete cascade not null
);
comment on table public.messages is 'Individual messages sent by each user.';

@dshukertjr Realtime Security (WALRUS) no longer sends flags but the old Realtime still does. I think #65 will help to maintain backwards compatibility.
