           builder: (context) => TakePicturePage(camera: camera)));

   setState(() {
     _path = result;
   });
 }

CodePudding user response：

Try to initialize ImagePicker like this

final ImagePicker _picker = ImagePicker();
final XFile? image = await _picker.pickImage(source: ImageSource.gallery);

Then you can access pickImage
