I’m writing a flutter app that interacts with some API, the first time I log in, the backend returns me a token that I save in SecureStorage. Then for each call I pass it in the header. To recover it from storage I do this:
String token = await SecureStorage.getToken();

class SecureStorage {
 static const _storage = FlutterSecureStorage();

 static Future<String> getToken() async {
   String token = await _storage.read(key: "authToken") ?? "";
   return token;
 }

static Future<bool> setToken(String authToken) async {
   await _storage.write(key: "authToken", value: authToken);
   return true;
 }
}

It has always worked, however once I put the app on testflight, we noticed that sometimes it happens that the token cannot be retrieved and therefore it is passed in vain. It seems like a question of timing. However I don’t understand why since I use await.

Could you kindly help me understand what the problem is?
Thank you!
