Version

9.1.0

Steps to Reproduce

Create app from template:

flutter create -t app my-app
cd my-app
flutter pub add sentry_flutter

Modify main.dart:

Future<void> main() async {
  await SentryFlutter.init((options) {
    options.dsn = 'some-dsn'; // insert dsn here
    options.diagnosticLevel = SentryLevel.debug;
  }, appRunner: () => runApp(const MyApp()));
}

Build and run:

flutter build linux
flutter run

Expected Result

Sentry builds and launches successfully.

Actual Result

Several warnings while compiling flutter build linux, still builds though.
