[BUG] cannot create launcher icons on web

[piratkin]

I'm trying to create a favicon for the web version and I'm getting the following error:

$ flutter pub run icons_launcher:create --path icons_launcher.yaml


╔════════════════════════════════════════════════════╗

This is my config file:

$ cat icons_launcher.yaml
# flutter pub run icons_launcher:create

    web:
      enable: true
      image_path: 'assets/images/favicon.png'
      favicon_path: 'assets/images/favicon.png'

Hello, @piratkin
Thank you for reporting. Now I have fixed this issue with the released v2.0.4.

You are right, it is. I updated and everything works.

Is it possible to make the background transparent?
