How to change the application launcher icon on Flutter?

**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][1]

**Update:**

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][1] instead though.

1. Update the pubspec.yaml
```
dev_dependencies:
icons_launcher: ^1.1.7

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

2. Run the package
```
flutter pub get
flutter pub run icons_launcher:main
```

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 create 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.

Without any packages

**Android**

1. Create an adaptive launcher icon in your Flutter project's root directory using the [Android Asset Studio.][1]

2. Add the generated launcher icon files to the project's `android/app/src/main/res/mipmap-*/` directories.

3. Edit the `android/app/src/main/AndroidManifest.xml` file and add the following line below the <application> tag:

`<application android:icon="@mipmap/ic_launcher">`

4. Run the `flutter build apk` command to generate an APK with the new launcher icon.

**iOS**

1. Create an Adaptive App Icon in your Flutter project's root directory using the [App Icon Generator][2].

2. Add the generated app icon files to the project's `ios/Runner/Assets.xcassets/AppIcon.appiconset/` directory.

3. Edit the `ios/Runner/Info.plist` file and add the following line below the <dict> tag:
```
<key>CFBundleIconName</key>
<string>AppIcon</string>
```
4. Run the flutter build ios command to generate an IPA with the new launcher icon.
