just checking.. did you place flutter_launcher_icons inside dev_dependencies and respected the indentation?

dev_dependencies:
  flutter_launcher_icons: "^0.5.2"
  flutter_test:
    sdk: flutter

# ... the other lines in your file ...

flutter_icons:
  android: true 
  ios: true
  image_path: "assets/icon/icon.png"

Tried both indentation each giving a different error

Error: The parameter 'path' of the method 'ConfigFilesystemLoader::loadConfig' has type dart.core::String, which does not match the corresponding type in the overridden method (dynamic).
Change to a supertype of dynamic (or, for a covariant parameter, a subtype).
 Future<String> loadConfig(String path) { ...

This last error means you fixed the problem you had! 😀 It was the yaml, you can close the issue.

This error you are currently getting is apparently a problem with the tool and flutter.

See the issue #39.
