Flutter: ImagePicker: await picker.pickImage(source: ImageSource.gallery) doesn't return

When I triggers the pickimage function, it pops up the gallery view to select an image. And when I choose an image, the app returns to app view. But the pickimage function doesn't return, and hangs forever. Here's my code:

import 'package:flutter/material.dart';
import 'dart:async';
import 'dart:io';

import 'package:flutter/foundation.dart';
import 'package:google_ml_kit/google_ml_kit.dart';
import 'package:image_picker/image_picker.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Text Scanning Demo'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);
  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {

  late String result;
  File? _image;
  InputImage? inputImage;
  final ImagePicker picker = ImagePicker();

  Future pickImageFromGallery() async {
    print("starting get image");
    final XFile? pickedFile = await picker.pickImage(source: ImageSource.gallery);
    //final pickedFile = await picker.pickImage(source: ImageSource.gallery);
    print("getting image.....");
    setState(() {
      if (pickedFile != null) {
        print("file not null");
        _image = File(pickedFile.path);
        inputImage = InputImage.fromFilePath(pickedFile.path);

        imageToText(inputImage);
      } else {
        print('No image selected.');
      }
    });
  }

  Future captureImageFromCamera() async {
    final pickedFile = await picker.pickImage(source: ImageSource.camera);
    setState(() {
      if (pickedFile != null) {
        _image = File(pickedFile.path);
        inputImage = InputImage.fromFilePath(pickedFile.path);
        imageToText(inputImage);
      } else {
        print('No image selected.');
      }
    });
  }

  Future imageToText(inputImage) async {
    print("starting");
    result = '';

    final textDetector = GoogleMlKit.vision.textDetector();
    print("loaded textDetector");
    final RecognisedText recognisedText = await textDetector.processImage(inputImage);
    print("loaded recognisedText");

    setState(() {
      String text = recognisedText.text;
      for (TextBlock block in recognisedText.blocks) {
        //each block of text/section of text
        final String text = block.text;
        print("block of text: ");
        print(text);
        for (TextLine line in block.lines) {
          //each line within a text block
          for (TextElement element in line.elements) {
            //each word within a line
            result += element.text + " ";
          }
        }
      }
      result += "\n\n";
    });
  }


  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Row(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Container(
              width: 100,
              child: TextField(
                textAlign: TextAlign.center,
                style: TextStyle(color: Colors.black),
              ),
            ),
            Container(
                height: 70,
                width: 150,
                child: TextButton(
                  style: TextButton.styleFrom(
                    primary: Colors.blue,
                  ),
                  onPressed: () {
                    pickImageFromGallery();
                  },
                  child: Text('Pick Image'),
                ))
          ],
        ),
      ),
      // This trailing comma makes auto-formatting nicer for build methods.
    );
  }
}

Here's screenshot of my Info from xcode: [note the privacy for gallery and camera][1]

I am at my wits end here, I followed every documentation, and it just doesn't even produce any error, and just hangs there. [1]: https://i.stack.imgur.com/XC6aP.png
