No output when Loading images from camera

[KanyantaM]

When I use the textAndImage method to get a response and the images are form the camera, I am not getting a response from Gemini.

ChatInputBox(
          controller: controller,
          onClickCamera: () async {
            showDialog(
                context: context,
                builder: ((context) {
                  return AlertDialog(
                    title: const Text('Image Selection'),
                    content: const Text(
                        'Do you want to use your camera or select an image from the gallery?'),
                    actions: [
                      TextButton(
                        onPressed: () async {
                          Navigator.pop(context);
                          // Capture a photo.
                          final XFile? photo = await picker.pickImage(
                              source: ImageSource.camera);

                          if (photo != null) {
                            photo.readAsBytes().then((value) => setState(() {
                                  selectedImage = value;
                                }));
