Hello, I had the same problem.

To solve it, it is necessary to import the external files, to your pubspec.yaml, in the assets section:

assets:
- .env

done that, you can import the load in the file in your main function:

await dotenv.load(fileName: ".env");

Hope this helps!

It doesn't work for me.

Same for me, Only when app is builded, then after a reload its works. Testing on a android emulator
here is my main func:

Future<void> main() async {
  initializeDateFormatting('pt_BR', null);

  WidgetsFlutterBinding.ensureInitialized();

  await dotenv.load(fileName: '.env');

  BlocOverrides.runZoned(
    () {
      runApp(const MyApp());
    },
    blocObserver: LogObserver(),
  );
}

I had the same problem.

The only way to make it work was to rename the .env file and remove the dot.

This works

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await dotenv.load(fileName: 'env.module');

  runApp(const MyApp());
}

To make it clear: this is only an Add-to-app problem (integrating a Flutter module in an existing Android/iOS app).
It works flawless in a normal Flutter project

await dotenv.load(fileName: "config.env");

• config.env
