After Adding the image picker my images are not printed in a flutter the screen is blank. I added import 'dart: io'; and import 'package:image_picker/image_picker.dart'; My image picker is in the alert dialog box, but when I choose an image from a file or gallery, it doesn't appear on that screen.

  GestureDetector(
                        onTap: () async {
                          await Permission.photos.request();
                          var status = await Permission.photos.status;
                          if (status.isGranted) {
                            File _pickedImage = await ImagePicker().pickImage(
                              source: ImageSource.gallery,
                              maxWidth: 100,
                              maxHeight: 100,
                            ) as File;
                            if (_pickedImage != null) {
                              setState(() {
                                pickedImage = _pickedImage;
                              });
                            }
                          } else if (status.isDenied ||
                              status.isPermanentlyDenied) {
                            showDialog(

                        ),
                      ),

I added dependencies: image_picker: ^0.8.5 3

Where you're printing the image, try this:

import 'dart:io';
...
...    
Image.file(
   File(pickedImage.path),
   fit: BoxFit.contain,
)
