[BUG] Using `dart run flutter_launcher_icons` destroys ios-project

[Manuel Rauber]

ℹ️ Info

Version: 0.13.1
Flutter: 3.10.5

💬 Description

I've set up my project according to the documentation with flavors.
Then I run dart run flutter_launcher_icon and afterwards I can not compile for iOS anymore due to:

Exception: Unable to get Xcode project information:

xcodebuild: error: Unable to read project 'Runner.xcodeproj'.
	Reason: The project ‘Runner’ is damaged and cannot be opened due to a parse error. Examine the project file for invalid edits or unresolved source control conflicts.

In the diff I can see:

As you can see at the bottom, there is this

roject object */;
}

inserted. I don't know, where it comes from. But it comes reliably everytime I run the command.

  # fonts:

I have this same problem. It doesn't respect flavors either

Reverting these changes works, but it makes automation difficult

I still have this problem, I try to use it with the flavor setup, but it directly breaks the ios build.

Update :

I fixed it with the following :

#491 (comment)

Before I did the procedure in this link, I rollback the changes in the 'project.pbxproj' file. In this way, I first solved the corruption problem of the iOS build.

Then I updated the app icons one by one as in this link. It worked.
