@devsontx please use markdown so your config has its original format

@christian-muertz I updated it. Thanks.

@MarkOSullivan94 any luck? :)

MarkOSullivan94 · 2018-07-20T09:01:20Z

Earliest I'll get a chance to have a quick look over it will be tomorrow.

@franzsilva could you investigate?

laughingpain · 2018-07-23T13:01:41Z

with flutter 0.5.1 beta no problems

volkangurol · 2018-07-23T18:44:55Z

i switched to flutter channel dev branch and updated - fixes the issue

As @volkangurol stated, after flutter channel dev, it worked as expected.

Damn ! I switched back to beta, then it worked 8°

flutter channel beta
flutter pub get
flutter pub pub run flutter_launcher_icons:main

Black voodoo magic, I tell you

MarkOSullivan94 · 2018-10-06T17:51:16Z

Is there anyone still having this issue?

christian-muertz · 2018-10-06T17:53:30Z

Gone! :D

Djameleddine21 · 2019-08-16T19:55:10Z

Hi ,
the problem is in the url of icon, because it's obligatory to make the icon in the folder icon like this :
flutter_icons:
image_path: "icon/icon.png"
android: true
ios: true
because if ou make in the path image_path: "assets/icon/icon.png" create a problem when you use the command flutter pub pub run flutter_launcher_icons:main

saif97 · 2019-09-02T16:58:58Z

In my case, this happened because I've used firebase (https://pub.dev/packages/cloud_firestore) for flutter web but the official dart plugin doesn't supported Flutter web yet.
