Problems with image picker-CodePudding

I am trying to use the image picker dependency, but I am running into a. a bit of a problem. Here is the function I created for the image picker:

 pickImage(ImageSource source)async{
    final ImagePicker imagePicker = ImagePicker();

   XFile? file =await imagePicker.pickImage(source: source);
   if(file != null){
     return file.readAsBytes();
   }else{
     print('no image selected');
   }
  }

this was created in a class called _authController. I then created another function for it to pick from the gallery specifically

Uint8List? _image;
  final AuthController _authController = AuthController();

  gallarypick()async{
   Uint8List im = await _authController.pickImage(ImageSource.gallery);
   setState(() {
     _image = im;
   });
  }

when i called the function, it gave me this error

I do not understand what is wrong. Help would be very much appreciated

CodePudding user response：

You probably installed the package and tries to execute its code directly, the image_picker package needs to get into native functionalities from the device, so it needs a re-run of your app, not hot restart/reload :

stop your app from running
run the flutter clean command
run the flutter pub get command

then run your debug app again, and it should work

CodePudding user response：

please add the necessary android permissions like below in android manifest file and let me know if it works

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

please refer to the link below which is of same kind.
