You can use package so it will take care of all this issue.

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
