return context.res.send(bytes, 200, {'Content-Type': 'application/pdf'});

type 'Uint8List' is not a subtype of type 'String' of 'body'
#0 main (package:generate_pdf/main.dart)

#1 Future.any.onValue (dart:async/future.dart:615)

Future<dynamic> main(final context) async {
  final pdf = PDF();
  final order = FakeOrder();
  var fakeOrder = order.createFakeOrder();
  context.log(fakeOrder.toJson().toString());
  final Uint8List? bytes = await pdf.createAndSave(fakeOrder);

  if (bytes != null) {
    context.log('PDF created.');
    context.log(bytes);

    return context.res.send(bytes, 200, {'Content-Type': 'application/pdf'});
  }

  return context.error("Someting gone wrong");
}

Hmm it's a little hard to tell from what you provided. Can you figure out exactly what's throwing the error?

this line return context.res.send(bytes, 200, {'Content-Type': 'application/pdf'});

ahhhh i see. that 1st parameter is supposed to be a string: https://github.com/open-runtimes/open-runtimes/blob/4044ed47c488e269a66fc381748f3af1e179e60b/runtimes/dart-3.0/src/function_types.dart#L42

Can you create a feature request for supporting non-strings?

I have created a pull-request

https://github.com/open-runtimes/open-runtimes/pull/212

Thanks for contributing ✨ Could you please also implement a test for it?

You will need to add a new case here: https://github.com/Shiba-Kar/open-runtimes/blob/main/tests/resources/functions/dart-3.0/lib/tests.dart#L118

In there, write a code that creates Uint8List, and sends it as response. To create it, you can read file, create it from string Hello World, or any other method that makes sense to you.

Next, you will need to add execution to a test script, which can be seen here: https://github.com/Shiba-Kar/open-runtimes/blob/main/tests/Base.php#L377-L388

In there you should expect specific response. Maybe bytes? Maybe multibytes? Maybe value after utf8 encoding? Not sure, do whatever feels natural to you and I will take a look during PR review.

Doing this will make tests in all other runtimes fail, but you can ignore that if you want to only focus on Dart. I can do the remaning languages, or we could ask other contributors. Just make sure they pass in Dart 3.0

Please let me know if you are intereste in continuing this PR, and if you have any questions 🙏

yes I am actively working on it
