Authentication persistence issues when upgrading Supabase Flutter from v1 to v2

🔵Flutter

auth

I want to ensure that users only need to log in the first time after downloading my mobile app, and save their user sessions so they don't need to re-authenticate every single time they open the app.

Previously on v1.10.0 of the

supabase_flutter

supabase_flutter

package (https://pub.dev/packages/supabase_flutter) I was able to make my authentication persist by storing the sessionString and recovering it when necessary with recoverSession:

String? sessionString = locator<SupabaseClient>().auth.currentSession?.persistSessionString;

await locator<SharedPreferences>().setString(
  supabaseSessionKey,
  sessionString,
);

await locator<SupabaseClient>().auth.recoverSession(sessionString);

String? sessionString = locator<SupabaseClient>().auth.currentSession?.persistSessionString;

await locator<SharedPreferences>().setString(
  supabaseSessionKey,
  sessionString,
);

await locator<SupabaseClient>().auth.recoverSession(sessionString);

Now that I have upgraded my Flutter and Supabase versions to the latest stable (v2),

persistSessionString

persistSessionString

is deprecated and I'm struggling to figure out how to get my authentication tokens to persist.

I've seen in the docs (https://supabase.com/docs/reference/dart/upgrade-guide) you can check if a session is expired with

Session? currentSession = locator<SupabaseClient>().auth.currentSession;
final isSessionExpired = session?.isExpired;

Session? currentSession = locator<SupabaseClient>().auth.currentSession;
final isSessionExpired = session?.isExpired;

but it seems like there isn't/ I shouldn't need to cache my session in v2. When I close and reopen the app I do not have an auth token anymore.

I am initializing in main as so:

await Supabase.initialize(
  url: supabaseUrl,
  anonKey: supabaseKey,
);

await Supabase.initialize(
  url: supabaseUrl,
  anonKey: supabaseKey,
);

Any help much appreciated, thanks!
