I am using image_picker: ^0.8.5 3 to help me pick images from either camera or gallery. I used getx in implementing the logic and I have added android:requestLegacyExternalStorage="true" to the Android manifest file because my android version is 29 . The problem is I keep getting this disturbing error

Unhandled Exception: MissingPluginException(No implementation found for method pickImage on channel plugins.flutter.io/image_picker_android)

I have researched it and in doing that i came across

below are samples of my code

This is the logic for picking the images

import 'dart:io';
import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'package:image_picker/image_picker.dart';

class ImageController extends GetxController {
var selectedImagePath = ''.obs;
var selectedImageSize = ''.obs;

void getImage(ImageSource imageSource) async {
final pickedFile = await ImagePicker().pickImage(source: imageSource);
if (pickedFile != null) {
  selectedImagePath.value = pickedFile.path;
  selectedImageSize.value =
      ((File(selectedImagePath.value).lengthSync() / 1024 / 1024)
              .toStringAsFixed(2)  
          "Mb");
} else {
  selectedImagePath.value = '';
  selectedImageSize.value = '';

  Get.snackbar(
    "Please Select Image",
    "No Image Selected",
    snackPosition: SnackPosition.BOTTOM,
    backgroundColor: Colors.red,
    colorText: Colors.white,
    borderRadius: 10,
    margin: EdgeInsets.all(10),
    borderColor: Colors.red,
    borderWidth: 2,
    duration: Duration(seconds: 2),
    icon: Icon(
      Icons.error,
      color: Colors.white,
    ),
  );
}

} }

And I am picking the images using this code

                  GestureDetector(
                  onTap: () {
                    Get.bottomSheet(
                      Container(
                        height: currentOrientation == Orientation.portrait
                            ? screenHeight * 0.10
                            : screenHeight * 0.22,
                        width: double.infinity,
                        decoration: BoxDecoration(
                          color: ProjectColors.kPrimaryColor,
                          borderRadius: BorderRadius.only(
                            topLeft: Radius.circular(
                              currentOrientation == Orientation.portrait
                                  ? screenHeight * 0.02
                                  : screenHeight * 0.05,
                            ),
                            topRight: Radius.circular(
                              currentOrientation == Orientation.portrait
                                  ? screenHeight * 0.02
                                  : screenHeight * 0.05,
                            ),
                          ),

                                imageController
                                    .getImage(ImageSource.camera);

                        : Image.file(
                            File(imageController.selectedImagePath.value),
                            fit: BoxFit.cover,
                          ),
                  ),
                ),

And this is the error message I keep getting.
