Gallery Access in Flutter

Difficulty Level : Expert
Last Updated : 30 Aug, 2020

We can add images from the gallery using the image_picker package in Flutter. For this, you’ll need to use your real device.

Follow the below steps to display the images from the gallery:

Step 1: Create a new flutter application:

flutter create <YOUR_APP_NAME>

Step 2: Now, delete the code from the main.dart file to add your own code.

Step 3: Add the dependency to your pubspec.yaml file:

pubspec

Step 4: Use the below code in the main.dart file :

main.dart

Dart

import 'dart:io'; 
import 'package:flutter/material.dart'; 
import 'package:image_picker/image_picker.dart'; 
  
void main() { 
  runApp(new MyApp()); 
} 
  
class MyApp extends StatelessWidget { 
  @override 
  Widget build(BuildContext context) { 
    return new MaterialApp( 
      home: new GalleryAccess(), 
      debugShowCheckedModeBanner: false, 
    ); 
  } 
} 
  
class GalleryAccess extends StatefulWidget { 
  @override 
  State<StatefulWidget> createState() { 
    return new GalleryAccessState(); 
  } 
} 
  
class GalleryAccessState extends State<GalleryAccess> { 
  File galleryFile; 
  
  @override 
  Widget build(BuildContext context) { 
    //display image selected from gallery 
    imageSelectorGallery() async { 
      galleryFile = await ImagePicker.pickImage( 
        source: ImageSource.gallery, 
        // maxHeight: 50.0, 
        // maxWidth: 50.0, 
      ); 
      setState(() {}); 
    } 
  
    return new Scaffold( 
      appBar: new AppBar( 
        title: new Text('Gallery Access'), 
        backgroundColor: Colors.green, 
        actions: <Widget>[ 
          Text("GFG",textScaleFactor: 3,) 
        ], 
      ), 
      body: new Builder( 
        builder: (BuildContext context) { 
          return Center( 
            child: new Column( 
              mainAxisAlignment: MainAxisAlignment.center, 
              children: <Widget>[ 
                new RaisedButton( 
                  child: new Text('Select Image from Gallery'), 
                  onPressed: imageSelectorGallery, 
                ), 
                SizedBox( 
                  height: 200.0, 
                  width: 300.0, 
                  child: galleryFile == null 
                      ? Center(child: new Text('Sorry nothing selected!!')) 
                      : Center(child: new Image.file(galleryFile)), 
                ) 
              ], 
            ), 
          ); 
        }, 
      ), 
    ); 
  } 
} 

Output:

When no image is selected, it will result:

interface

When the button is pressed, it will ask for accessing photos, media, and files on your device as shown below:

When the permission is given to access photos and any image is selected from the gallery, it will be displayed on the screen as shown below:

Explanation:

import image_picker package in main.dart file.
for a gallery image, we have async function imageSelectorGallery() and await for gallery image.
the image will be displayed after loaded.
