How to change the application launcher icon on Flutter?

Question

When I create an app with a flutter create command, the flutter logo is used as an application icon for both platforms.

If I want to change the app icon, shall I go to both platforms directories and replace images there?, by platforms directories I mean myapp/ios/Runner/Assets.xcassets/AppIcon.appiconset for iOS and myapp/android/app/src/main/res for Android.

Or is it possible to define an image as a Flutter Asset and the icons are generated somehow?.

you can update appicon with two way, i have mention both way check [here](https://stackoverflow.com/a/62401560/8265484) — Mayur Dabhi, Jun 16 '20 at 05:38

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

Is there any requirement for the image? – camino Aug 21 '18 at 00:32

Do you have a recommended image size for the `image_path` image? – Suragch Jan 24 '19 at 21:52
I wouldn't be able to say with confidence which is the best @Suragch. In my tests I've always used 3 different sizes. You can find these within the test directory of the GitHub project page: https://github.com/fluttercommunity/flutter_launcher_icons/tree/master/test – Mark O'Sullivan Jan 25 '19 at 14:08
2

I only found a reference to one size, `710x599`. What was the reason for choosing that? I would have expected `512x512` or `1000x1000` or something square anyway. – Suragch Jan 25 '19 at 17:16
2

@Suragch just did a quick search for an icon on Google so I could quickly test it. I included two other icon sizes so people could try out the package (1024x1024 and 128x128), you can find these here: https://github.com/fluttercommunity/flutter_launcher_icons/tree/master/example/assets/images – Mark O'Sullivan Jan 25 '19 at 23:57
@MarkO'Sullivan, I haven't looked deeply into how your package resizes the images, so correct me if I'm wrong, but I would think that 128x128 would not be a desirable size. Is there a use case for it (outside of testing)? Wouldn't it require upscaling for the some of the larger image requirements of Android and iOS? Anyway, 1024x1024 sounds reasonable and I'll go with that. – Suragch Jan 26 '19 at 01:26
Yep I've always noticed better performance with 1024x1024 out of all the example assets – Mark O'Sullivan Oct 10 '19 at 09:23

Can I suggest that the packages read.me should provide recommendations on images sizes. – Brett Sutton Nov 09 '19 at 07:18
Great tool, works like a charm. .svg support would be nice, but works well with .png – Jens Jan 20 '20 at 00:32

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.

(lion clipart from here)

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.

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.

@MarkO'Sullivan, thank you. My guess is that the package is fine. It is just that the documentation was hard for me to follow. For example, what size to use for the initial image, are the background layers getting created for Android, etc. It would be really helpful to have a detailed tutorial to guide a beginner through the process. – Suragch Apr 12 '19 at 21:22
Good alternative to the package, which is not official, does not seem to work anymore, and has not been updated for 6 months... – Yann39 May 21 '19 at 12:33

This helped. Within Android Studio, there is no option to add *Image Asset*. The work around I learnt from a github/flutter issue is to open the /android folder (within the flutter project) as a standard alone "Android" project within Android Studio. The option will appear when you right-click on the /res folder. – MwamiTovi Jan 02 '20 at 05:26
5

@MwamiTovi is right, however you need to wait for gradle sync before right-clicking or even sync manually, otherwise "new -> image asset" will not show. – Daniel Feb 06 '20 at 14:25
This is a far better and easier solution. You only need to create one 1024x1024 background image and one foreground image that size or smaller. The Image Asset dialog takes care of the rest! – johnw182 Mar 14 '20 at 15:27

I can't found New>Image Asset option after right clicking on both android and android/app folder on latest version of android studio. – mrb Mar 18 '20 at 12:43

So good to see a step-by-step answer with relevant screenshots etc. – DroidOS Apr 01 '20 at 13:20

Thank you so much! This solution actually did the trick for Android. For whatever reason, the icons generated flutter_launcher_icons were showing small in the launcher, not covering the whole thing. Maybe I missed something, but it appears as straight forward as other have mentioned, yet it didn't work. Using Android Studio worked perfectly! Thank you! – davidcv5 Aug 21 '20 at 02:33
In the Asset Studio window I have an error saying: Project must be built with SDK 26 or later to use adaptive icons. The error prevents me for saving the icon. any approach for that? – Taba Sep 03 '20 at 09:01
1

@Taba Try opening the just `android` folder of your Flutter project using Android Studio. https://stackoverflow.com/questions/50778020/can-i-use-android-8-0-adaptive-icons-for-a-flutter-app – Suragch Sep 03 '20 at 11:25
3

For me, when I clicked on New > Image Asset, nothing happens. For anybody having this problem, just go to File > Open, navigate to the "android" folder of your flutter project and open it. Wait for it Android Studio to sync (it took about 2 minutes for me). Once it's loaded, open the "app" folder, right click on the "res" folder, then New > Image Asset. That worked for me. (Source: https://github.com/flutter/flutter-intellij/issues/3512#issuecomment-516252436) – Derence Feb 02 '21 at 01:50

@Derence, thanks for adding that comment. – Suragch Feb 02 '21 at 01:53
Thank you! this worked perfectly, and was much easier since everything just worked out with the sizing. the pub.dev flutter lib for making this "easy" was not doing very well with the image size. – Eradicatore Feb 11 '21 at 01:07

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

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.

Hope this will helps others.

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

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

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.

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

When a new Flutter app is created, it has a default launcher icon. To customize this icon, you might want to check out the flutter_launcher_icons package.

Alternatively, you can do it manually using the following steps. This step covers replacing these placeholder icons with your app’s icons:

Android

Review the Material Design product icons guidelines for icon design.
In the <app dir>/android/app/src/main/res/ directory, place your icon files in folders named using configuration qualifiers. The default mipmap- folders demonstrate the correct naming convention.
In AndroidManifest.xml, update the application tag’s android:icon attribute to reference icons from the previous step (for example, <application android:icon="@mipmap/ic_launcher" ...).
To verify that the icon has been replaced, run your app and inspect the app icon in the Launcher.

iOS

Review the iOS App Icon guidelines.
In the Xcode project navigator, select Assets.xcassets in the Runner folder. Update the placeholder icons with your own app icons.
Verify the icon has been replaced by running your app using a flutter run.

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.

  ios: false

# The following section is specific to Flutter.

  # For details regarding fonts from package dependencies,
  # see https://flutter.dev/custom-fonts/#from-packages

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

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.
