[BUG] Web icons generation using package source does not work

[masus04]

:information_source: Info

Version: 0.10.0

:scroll: Pubspec.yaml

flutter_icons: image_path_android: "packages/flutter_utils/assets/launcher_icon_android.png" adaptive_icon_foreground: "packages/flutter_utils/assets/launcher_icon_android.png" adaptive_icon_background: "#ffffff" image_path_ios: "packages/flutter_utils/assets/launcher_icon_ios.jpg" web: generate: true image_path: "packages/flutter_utils/assets/mtc_launcher_icon.png"

:speech_balloon: Description

While for android I was able to specify an asset from an imported package, the same is not possible for the web platform.

When generating the icons using the pubspec.yaml above I receive the following output:

  ════════════════════════════════════════════
     FLUTTER LAUNCHER ICONS (v0.10.0)
