Env file not readable in an isolate

[ciprianteletin]

Hi, currently I am running flutter_dotenv 5.1.0, with dart --version 3.1.5
Inside my isolate code, I am calling dotenv.load(file) since I need in my process some of the environment variables defined in the file. The error does not appear if I remove the dotenv.load(file) call from the isolate.

The error is the following:

[VERBOSE-2:dart_vm_initializer.cc(41)] Unhandled Exception: UI actions are only available on root isolate.

I see that the load method is calling WidgetsFlutterBinding.ensureInitialized() in the background which is causing the error from above.
