1. Buka browser di https://pub.dev/ :

kemudian masukkan code dibawah pada dile .yaml :

2. Import code pad file main.dart:

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

void main() => runApp(MaterialApp(
 home: AksesKamera(),
 debugShowCheckedModeBanner: false,
));

class AksesKamera extends StatefulWidget {
 @override
 _AksesKameraState createState() => _AksesKameraState();
}

class _AksesKameraState extends State<AksesKamera> {
 File image;
 aksesCamera()async{
   print('Picker is Called');
   File img = await ImagePicker.pickImage(source: ImageSource.camera);
   if (img != null){
     image = img;
     setState(() {

     });
   }
 }

 @override
 Widget build(BuildContext context) {
   return Scaffold(
     appBar: AppBar(
       title: Text('Akses Kamera'),
       backgroundColor: Colors.green,
     ),
     body: Center(
       child: Container(
         child: image == null ? Text('No Image To Show') :
    Image.file(image),
       ),
     ),
     floatingActionButton: FloatingActionButton(
       backgroundColor: Colors.green,
       child: Icon(Icons.add_a_photo),
       onPressed: aksesCamera,
     ),
   );
 }
}

3. Agar dapat berjalan lancar pada saat kita running aplikasi kita didalam iOS kita perlu menambahkan script dibawah ini pada file ​ info.plist ​ tepatnya didalam folder ​ ios​ / ​ Runner/info.plist ​ kita ketikan script berikut ini

....
<​ key​ >NSPhotoLibraryUsageDescription</​ key​ >
<​ string​ >We need this ​ key​ ​ to​ ​ get​ photo ​ from​ gallery </​ string​ >
<​ key​ >NSCameraUsageDescription</​ key​ >
<​ string​ >We need this ​ key​ ​ to​ ​ get​ photo ​ from​ camera source </​ string​ >
<​ key​ >NSMicrophoneUsageDescription</​ key​ >
....

4. Setelah itu coba jalankan pada emulator atau samartphone, dan tampilannya :
