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  gt  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  quot  mipmap ic launcher quot   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  gt  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

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
