      await _requestPermissions();
      final ImagePicker picker = ImagePicker();
      final XFile? image = await picker.pickImage(source: ImageSource.camera);

      if (image != null) {
        setState(() `{`
          selectedImage = File(image.path);
        });
      } catch (e, stackTrace) {

I cannot reproduce the issue with the latest stable, do you experience the problem with the code sample below?

I'm facing this issue specifically for this device version Device Model: OnePlus A5000 Android Version: 9.0 (Pie)

@akshaykap11 It seems you mistyped the package name as I don't see image_capture on pub.dev. So I updated the description to image_picker instead (based on the issue title). Please correct me if I'm wrong (in case you have a private package named image_capture)

When the issue happens, is the app terminated? Can you provide the entire crash stack trace?

Also, what is the current image_picker version? Can you confirm with the sample code Iapicca shared above?

[akshaykap11]

The app is not terminated. The flow is something like this 1) I click the cta action 2) camera preview opens 3) i click the pic which shows me a tick icon with the captured image. 4) once i click the tick icon, i get back to the app 5) Here expectation - image captured should show in the image container actual results - placeholder is still there

-> I dont have the device with me now. Will share the entire crash stack trace in few days once I get the device -> Image picker version - image_picker: ^1.1.2

-> Also will try the sample code with the device and update here again

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now. If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones. Thanks for your contribution.
