How to change the application launcher icon on Flutter?

Flutter Launcher Icons has been designed to help quickly generate launcher icons for both Android and iOS: https://pub.dartlang.org/packages/flutter_launcher_icons

Add the package to your pubspec.yaml file (within your Flutter project) to use it

Within pubspec.yaml file specify the path of the icon you wish to use for the app and then choose whether you want to use the icon for the iOS app, Android app or both.

Run the package

Voila! The default launcher icons have now been replaced with your custom icon

I'm hoping to add a video to the GitHub README to demonstrate it

Video showing how to run the tool can be found here.

If anyone wants to suggest improvements / report bugs, please add it as an issue on the GitHub project.

Update: As of Wednesday 24th January 2018, you should be able to create new icons without overriding the old existing launcher icons in your Flutter project.

Update 2: As of v0.4.0 (8th June 2018) you can specify one image for your Android icon and a separate image for your iOS icon.

Update 3: As of v0.5.2 (20th June 2018) you can now add adaptive launcher icons for the Android app of your Flutter project

Setting the launcher icons like a native developer

I was having some trouble using and understanding the flutter_launcher_icons package. This answer is how you would do it if you were creating an app for Android or iOS natively. It is pretty fast and easy once you have done it a few times.

Android

Android launcher icons have both a foreground and a background layer.

(image adapted from Android documentation)

The easiest way to create launcher icons for Android is to use the Asset Studio that is available right in Android Studio. You don't even have to leave your Flutter project. (VS Code users, you might consider using Android Studio just for this step. It's really very convenient and it doesn't hurt to be familiar with another IDE.)

Right click on the android folder in the project outline. Go to New > Image Asset. (Try right clicking the android/app folder if you don't see Image Asset as an option. Also see the comments below for more suggestions.) Now you can select an image to create your launcher icon from.

Note: I usually use a 1024x1024 pixel image but you should certainly use nothing smaller that 512x512. If you are using Gimp or Inkscape, you should have two layers, one for the foreground and one for the background. The foreground image should have transparent areas for the background layer to show through.

This will replace the current launcher icons. You can find the generated icons in the mipmap folders:

If you would prefer to create the launcher icons manually, see this answer for help.

Finally, make sure that the launcher icon name in the AndroidManifest is the same as what you called it above (ic_launcher by default):

application android:icon="@mipmap/ic_launcher"

Run the app in the emulator to confirm that the launcher icon was created successfully.

iOS

I always used to individually resize my iOS icons by hand, but if you have a Mac, there is a free app in the Mac App Store called Icon Set Creator. You give it an image (of at least 1024x1024 pixels) and it will spit out all the sizes that you need (plus the Contents.json file). Thanks to this answer for the suggestion.

iOS icons should not have any transparency. See more guidelines here.

After you have created the icon set, start Xcode (assuming you have a Mac) and use it to open the ios folder in your Flutter project. Then go to Runner > Assets.xcassets and delete the AppIcon item.

https://i.stack.imgur.com/lb9io.png

After that right-click and choose Import.... Choose the icon set that you just created.

That's it. Confirm that the icon was created by running the app in the simulator.

If you don't have a Mac...

You can still create all of the images by hand. In your Flutter project go to ios/Runner/Assets.xcassets/AppIcon.appiconset.

The image sizes that you need are the multiplied sizes in the filename. For example, Icon-App-29x29@3x.png would be 29 times 3, that is, 87 pixels square. You either need to keep the same icon names or edit the JSON file.

Follow simple steps:

1. Add flutter_launcher_icons Plugin to pubspec.yaml

e.g.

dev_dependencies: 
  flutter_test:
    sdk: flutter

  flutter_launcher_icons: "^0.9.0"

flutter_icons:
  image_path: "icon/icon.png" 
  android: true
  ios: true
  # optionally, as transparency is not allowed on app store
  # remove_alpha_ios: true

2. Prepare an app icon for the specified path. e.g. icon/icon.png

3. Execute command on the terminal to Create app icons:

$ flutter pub get

$ flutter pub run flutter_launcher_icons:main

To check check all available options and to set different icons for android and iOS please refer this

Update:

flutter_launcher_icons 0.8.0 Version (12th Sept 2020) has Added flavours support

Flavors are typically used to build your app for different environments such as dev and prod

The community has written some articles and packages you might find useful. These articles address flavors for both iOS and Android.

I have changed it in the following steps:

1) please add this dependency on your pubspec.yaml page

 dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_launcher_icons: ^0.7.4

2) you have to upload an image/icon on your project which you want to see as a launcher icon. (i have created a folder name:image in my project then upload the logo.png in the image folder). Now you have to add the below codes and paste your image path on image_path: in pubspec.yaml page.

flutter_icons:
  image_path: "images/logo.png"
  android: true
  ios: true

3) Go to terminal and execute this command:

flutter pub get

4) After executing the command then enter below command:

flutter pub run flutter_launcher_icons:main

5) Done

N.B: (of course add an updated dependency from

https://pub.dev/packages/flutter_launcher_icons#-installing-tab-

)

You have to replace the Flutter icon files with images of your own. This site will help you turn your png into launcher icons of various sizes:

App Icon Creator

Step-1: upload The Image,

Step-2: Make necessary Changes And Click on download(dont change the file name)

Step-3: Extract the Downloaded Zip File In the respective folder

android/app/src/main/res

Best & Recommended way to set App Icon in Flutter.

I found one plugin to set app icon in flutter named flutter_launcher_icons. We can use this plugin to set the app icon in flutter.

Add this plugin in pubspec.yaml file in project root directory. Please check below code,

dependencies:    
 flutter:    
  sdk: flutter    
 cupertino_icons: ^0.1.2    
 flutter_launcher_icons: ^0.7.2+1**    

Save the file and run flutter pub get on terminal.

Create a folder assets in the root of the project in folder assets also create a folder icon and place your app icon inside this folder. I will recommend to user 1024x1024 app icon size. I have placed app icon inside icon folder and now I have app icon path as assets/icon/icon.png Now, in pubspec.yaml add the below code,

flutter_icons:    
 android: "launcher_icon"    
 ios: true    
 image_path: "assets/icon/icon.png"

Save the file and run flutter pub get on terminal. After running command run second command as below

flutter pub run flutter_launcher_icons:main -f pubspec.yaml 

Then Run App

Flutter has its own default icon for every app in its Android and Ios folder so there are few steps that I would like to show to change the app icon.

Head over to https://appicon.co/ and generate your own icon using icon image (the zip file contains two main folders android and Assets.xcassets) For android: Go inside android\app\src\main\res in your flutter app and there paste the android folder content. For IOS: Go inside ios\Runner in your flutter app and there paste the Assets.xcassets content Restart your emulator or rebuild your application 😁

Best way is to change launcher icons separately for both iOS and Android.

Change the icons in iOS and Android module separately. The plugin produces different size icons from the same icon which are distorted.

Follow this link: https://flutter.dev/docs/deployment/android

Follow these steps:-

1. Add dependencies of flutter_luncher_icons in pubspec.yaml file.You can find this plugin from here.

2. Add your required images in asstes folder and pubspec.yaml file as below .

pubspec.yaml

name: NewsApi.org
description: A new Flutter application.

# The following line prevents the package from being accidentally published to
# pub.dev using `pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

3. Then run the command in terminal flutter pub get and then flutter_luncher_icon.This is what I get the result after the successfully run the command . And luncher icon is also generated successfully.

My Terminal

[E:\AndroidStudioProjects\FlutterProject\NewsFlutter\news_flutter>flutter pub get
Running "flutter pub get" in news_flutter...                       881ms

I use few methods for chaging flutter app lancher icon but only the manuall method is a bit easy and good. Because you will know how it work.

So to change flutter ios icon. First get copy of your icon 1024×1024 pixel and generate set of icons for android and ios using appicon.co generator. When you get zip file it work contact two folder ios and android open ios folder and copy folder and replace the one in your ios/runner directory.

For android copy all folder present in android folder and replace the ones present in the android/app/src/main/res/drawable here.

After replacing folder on both ios and android stop the app and re run and your icons will be changed.

Try IconKitchen, the successor to the Android Asset Studio, and a great new way to make highly customizable app icons for Android, iOS, and the web.

---

the easy way is to use flutter_launcher_icons package but doesn't work perfectly so I prefer to use this website app icon to make app icons for android and ios then you only need to replace the mipmap folders for ANDROID under android/app/src/main/res/ and assets Assets.xcassets for IOS under ios/Runner/

The flutter_launcher_icons package recommended in many answers above hasn't been updated for quite some time now and is throwing an uncaught exception.

You can use the package icons_launcher instead though.

Update the pubspec.yaml

dev_dependencies:
  icons_launcher: ^1.1.7

flutter_icons:
  image_path: 'assets/ic_logo_border.png'
  ios: true
  android: true

Run the package

flutter pub get
flutter pub run icons_launcher:main

---

you can achieve this by using flutter_launcher_icons in pubspec.yaml

another way is to use one for android and another one for iOS
