【flutter】モバイルアイコンを設定する際のエラー対処方法

flutter_launcher_icons設定

pubspec.yaml

dev_dependencies:
  flutter_launcher_icons: ^0.7.0
flutter_icons:
  image_path: "assets/images/icon.png"
  ios: true
  android: true

flutter_launcher_iconsを使いアプリアイコンを設定したところ下記エラーが出ました。

flutter_launcher_icflutter packages pub run flutter_launcher_icons:main
