I am facing an issue when I use firebase to authenticate with GCP Secret Manager in Flutter:
[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: Null check operator used on a null value
#0 clientViaApplicationDefaultCredentials (package:googleapis_auth/auth_io.dart:77:49)On Mac I launch in iTerm:
export GOOGLE_APPLICATION_CREDENTIALS="PATH_TO_JSON_FILE/service-account-file.json"Then my code is:
import 'package:googleapis/secretmanager/v1.dart';
import 'package:googleapis_auth/auth_io.dart' as auth;
import 'package:googleapis/firestore/v1.dart';
final client = await auth.clientViaApplicationDefaultCredentials(scopes: [FirestoreApi.cloudPlatformScope]);
final api = SecretManagerApi(client);
final secrets = await api.projects.secrets.versions.access('my_secret_key');
print(secrets.payload!.data.toString());When I launch the app, I have Platform.environment['GOOGLE_APPLICATION_CREDENTIALS']: null
What is the proper ways to set this variable?
