Image is not picked in imagepicker - flutter

Question

I am trying to work with image picker where I will pick an image from gallery and it will change in aa given circle avatar when picked.
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';
//import 'package:firebase_core/firebase_core.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'package:image_picker/image_picker.dart';
class AddDoctor extends StatefulWidget {
#override
State<AddDoctor> createState() => AddDoctorState();
}
class AddDoctorState extends State<AddDoctor> {
File? _image;
pickImage() async {
final ImagePicker imagePicker = ImagePicker();
final galleryFile =
await imagePicker.pickImage(source: ImageSource.gallery) as File;
if (galleryFile == null) {
return galleryFile.readAsBytes();
} else {
print('No Image Selected');
}
setState(() {
_image = galleryFile;
});
}
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: const Color(0xFFD9E4EE),
appBar: AppBar(
title: const Text('Add Doctor'),
actions: [
IconButton(
icon: const Icon(Icons.menu),
onPressed: () {},
),
],
),
body: ListView(
padding: const EdgeInsets.all(16),
children: <Widget>[
CircleAvatar(
radius: 40,
backgroundImage: _image != null ? FileImage(_image!) : null,
),
const SizedBox(height: 10),
ElevatedButton(
onPressed: () {
pickImage();
},
child: const Text('Upload Image'),
),
const SizedBox(height: 10),
],
),
);
}
}
But in the debug console it's showing problem like Image not selected (which is set in my if condition at the beginning) and something like: Unhandled Exception: type 'XFile' is not a subtype of type 'File' in type cast

Answer 1

final galleryFile =
await imagePicker.pickImage(source: ImageSource.gallery) as File;
here "As file" type cast is causing the problem because
The image picked is type of Object XFile and you're declaring it a File object so it's giving error type 'XFile' is not a subtype of type 'File' in type cast.
you can convert or use file path like this
final pickedXFile = await imagePicker.pickImage(source: ImageSource.gallery);
final galleryFile = File(pickedXFile.path);
