The version of the SDK (See pubspec.lock): 6.4.0

I have initialized Sentry using the runZonedGuarded approach and there are 3 messages (included in Actual Result section) logged to the console. Initialization roughly looks like as shown below:

Steps to reproduce

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

      await ConfigReader.initialize();
      await KeyValueStorageBase.init();

      // Lock app orientations to just potrait.
      SystemChrome.setPreferredOrientations([
        DeviceOrientation.portraitUp,
        DeviceOrientation.portraitDown,
      ]);

      // Reads the environment variable for APP_ENV.
      final appEnv = AppConfig.AppEnv;

      // Initialize app with Sentry only when running in "production" or "stage".
      if ([AppEnv.production.name, AppEnv.stage.name].contains(appEnv)) {
        debugPrint('App running in $appEnv .. initializing Sentry.');
        debugPrint('Got Sentry DSN: ${AppConfig.SentryDSN}');

        await SentryFlutter.init(
          (options) => options
            ..dsn = AppConfig.SentryDSN
            ..environment = appEnv
            ..tracesSampleRate = 1.0,
          appRunner: () => runApp(
            const App(),
          ),
        );
      } else {
        debugPrint('App running in development mode.');
        runApp(const App());
      }
    },
    (error, trace) async {
      await Sentry.captureException(error, stackTrace: trace);
    },
  );
}

With the aforementioned rough initialization and running the app in debug mode using flutter run, the issue can be reproduced.

Solutions tried

Here are few things I have tried to verify that this issue occurs on any device:

The device I usually run this app, is configured to use the SD card as the internal storage. My first thought was regarding this, so I changed devices but still getting the same error.
Last month, I had used Sentry (v6.3.0) with another app, which had no issues whatsoever. So, I downgraded to v6.3.0 but still the same issue.
After searching for similar issues (surprisingly the results were scarce and not related to Dart), few people suggested to add the "external storage" permissions in AndroidManifest.xml, still the same issue.
```
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
```
This is related to point 3, that the "external storage" permissions are required to be obtained during runtime, which was done using the permission_handler package but to no avail.

Actual result

Sentry does not catch any exceptions. Instead, it throws the following logs:

# The following 2 logs show up during the initial booting of the application.
D/Sentry  ( 6892): SU isn't found on this Device.

W/pool-3-thread-1( 6892): type=1400 audit(0.0:2417): avc: denied { read } for name="version" dev="p:s0:c216,c256,c512,c768 tcontext=u:object_r:proc_version:s0 tclass=file permissive=0

# This is logged whenever Sentry encounters an exception.
I/Sentry  ( 6892): Not possible to read external files directory

Expected result

Sentry should report the exceptions produced within the app.
