Framework not being set

[mgalgs]

Ever since I upgraded from 0.2.0-beta (yes, I was a few years out of date) to 1.5.0 my Rollbar items from my Flutter app haven't been getting a "Framework" value. So I have to filter by "UKNOWN" framework in my Rollbar items view in order to see issues from my app.

You can see in the following screenshot that after I shipped the new version of my app the framework field went empty (except for the odd report or two from folks running an old version of the app):

Am I missing something in initialization to get this set or this is a bug in the package?

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  PackageInfo packageInfo = await PackageInfo.fromPlatform();

  var config = Config(
    accessToken: '...',
    package: '...',
    codeVersion: packageInfo.version,
    handleUncaughtErrors: true,
    includePlatformLogs: true,
  );

  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );

  await RollbarFlutter.run(config, () => runApp(MyApp()));
}

It's strange because if I click on an item and view its parameters I do see "flutter" in the framework field. But somehow that's not being populated in the rest of the UI or something.

Old rollbar version (note the Flutter logo):

New rollbar version (note the lack of Flutter logo):

So whatever is causing the Flutter logo to be populated must be separate from the "framework" value in the "Params" list.
