I Tried changing my app's Icon on apk but it's not changing. I generated an icon on https://appicon.co/ and try changing but it's showing flutter's default app icon.

Try this flutter_launcher_icons

In pubsec.yaml

 dev_dependencies:
  flutter_launcher_icons: "^0.10.0"

flutter_icons:
  android: true
  ios: true
  image_path: "assets/icon/icon.png"
  min_sdk_android: 21 # android min sdk min:16, default 21

And then run this on your terminal (from android studio)

flutter pub run flutter_launcher_icons:main

The command will regenerate icons for android and ios. You can check it in the corresponding folders (eg for android : app/src/main/res/drawable-xxx/ic_launcher)

If you are coming from the future and you have difficulty using the flutter_launcher_icons package.

In July 2022, I tried using the flutter_launcher_icons package (version: "^0.9.2") but it did not work when running the

flutter pub run flutter_launcher_icons:main

and got the famous error 255 code.

After a little search on google, I came across this (very short) and followed this article here: https://www.codewithflutter.com/how-to-change-application-launcher-icon-in-flutter/.

This is what I did to get a launcher icon for the devices that my app would run on. It's a simple 3 step method to change the app launcher icon.

Step 1:

Go to https://appicon.co/ and use select your launcher's image file.

For best results, it should be 1024 x 1024 pixels. Select the devices for which you would like the app icon to be generated for. Click on the "Generate" button and a zip file would be downloaded.

When you open the downloaded zip file, it would normally contain the "android" and the "Assets.xcassets" folders (assuming you are generating for both android and ios devices).

Step 2:

Changing the icons manually.

This process is just copying and pasting the folders.

For android:

Open the AppIcons\Android folder and copy all the sub folders. Then go the android\app\src\main\res folder and paste it (replace the existing file to new files).

For ios:

Open the AppIcons folder and copy the Assets.xcassets folder. Then go the ios/Runner and paste it (replace the existing file to new files).

Step 3:

Run the command flutter run

Thank you!
