Launch new, external Activity, from Flutter android MainActivity

Question

I'm trying to write some native code in my Flutter app to integrate with Zendesk using their SDK. Thus far, my Flutter app has not required me to drop down and write any actual native code, so I'm getting a bit stuck here. What I have looks like this:

public class MainActivity extends FlutterActivity {
    private static final String ZENDESK_CHANNEL = "zendesk";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        GeneratedPluginRegistrant.registerWith(this);
        new MethodChannel(getFlutterView(), ZENDESK_CHANNEL).setMethodCallHandler(
                this::invokeZendesk);
    }

    private void invokeZendesk(MethodCall call, MethodChannel.Result result) {
        if (call.method.equals("init")) {
            Zendesk.INSTANCE.init(this, "https://myapp.zendesk.com",
                    "myappid",
                    "myclientid");
            Identity identity = new AnonymousIdentity();
            Zendesk.INSTANCE.setIdentity(identity);

            Support.INSTANCE.init(Zendesk.INSTANCE);
        } else if (call.method.equals("launch")) {
            RequestActivity.builder().show(this);
        }
    }
...

When I invoke the "launch" code I get this error:

When googling for that particular error I find some things about ensuring that you create an AppCompat theme for your activity, etc. but since this is not my own activity that I'm trying to launch, I'm not really sure what to do here.

There is not enough data here to answer your question. If I understand correctly this line has the problem - "RequestActivity.builder().show(this);" ? — crazyPixel, Mar 30 '20 at 23:28
@crazyPixel - yes, that is the line that's causing the issue. What other information would be helpful for me to provide? — cloudwalker, Mar 30 '20 at 23:32
Where does RequestActivity comes from? is it a local activity you created? was it provided by some SDK? — crazyPixel, Mar 30 '20 at 23:35
It is provided by the Zendesk SDK, so it's not one of my activities. — cloudwalker, Mar 31 '20 at 00:01
