Do I need to do anything to be able to see context (local variables, etc) in my Flutter stack traces? Currently it always says No context to show!

This is how I'm initializing Rollbar in my app:
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()));
}
