Java.lang.RuntimeException: An error occurred while executing doInBackground() in Release mode

Hello,

I seem to be having issues when building the app in release mode as when I initiate the task I get the following exception:

E/AndroidRuntime(28329): FATAL EXCEPTION: AsyncTask #1

However when on debug mode the app runs flawlessly. What could be the issue?

I've tried different devices and flutter versions, I still have the same issues I'm afraid.

Here is the relevant code:

  void handleSuccess(ip, bssid) {
    completed = true;
    Get.to(SuccessPage(ip, bssid));
  }

  void handleFail(sub) async {
    sub.cancel();
    print("cancelled!!!!");
    if (!completed) {
      Get.off(FailPage());
    }
  }

  void espSetup() async {
    print("WiFi: " + wifiName);
    print("BSSID: " + wifiBSSID);
    print("PSK: " + wifiPSK);

    final task = ESPTouchTask(
      ssid: wifiName,
      bssid: wifiBSSID,
      password: wifiPSK,
    );
    stream = task.execute();
    final sub = stream.listen((r) {
      handleSuccess(r.ip, r.bssid);
    });
    Future.delayed(Duration(minutes: 1), () {
      handleFail(sub);
    });
  }

  Stream<ESPTouchResult> stream;

Could you provide us a minimal reproducible example with code and instructions on how to reproduce the issue?

I managed to fix the issue at the end, I belive I had to tweak the API version
