IMPORTANT - Error with null-safety about shifting_tabbar

[pMertDogan]

I have the same problem with this package and git. Error is simple to fix. There is a casting problem like @emem365 mentioned.

'Class? ' cant be cast as 'Class' that's null safety

[emem365]

@MisterB2B That seems right. The error is originating from:
https://github.com/mahdizakizadeh/shifting_tabbar/blob/15ea24350e9871f3290ceb2edf8e58bfdd15a217/lib/shifting_tabbar.dart#L118

The return type for the function is List<_ShiftingTabWidget?> while the type Cast expects the type List<_ShiftingTabWidget>.
The fix is simple enough:
https://github.com/mahdizakizadeh/shifting_tabbar/blob/15ea24350e9871f3290ceb2edf8e58bfdd15a217/lib/shifting_tabbar.dart#L131-L150
Every _ShiftingTabWidget? should be replaced with _ShiftingTabWidget, which seems correct from the point of null safety as well, since no _ShiftingTabWidget can be null.
I tried cloning the repository but there seems to be an error with some path, which makes it so that I can't clone the repository, nor does a git ref work in pubspec.yaml, since even that cannot clone the repository.
This is the error I face while cloning the repo

Resolving deltas: 100% (115/115), done.
error: invalid path 'example/build\ios/Runner.build/Release-iphoneos/Runner.build/dgph'
fatal: unable to checkout working tree
warning: Clone succeeded, but checkout failed.
You can inspect what was checked out with 'git status'
and retry with 'git restore --source=HEAD :/'                                                                                                                           

So I cannot really drop a PR or a fix for this issue as of now

Hello everyone,
I apologize for the late reply to the issue. Because I am a full-time student, I do not have much free time, and it's been a long time that I have not worked with Flutter. I would be happy if someone solves the problem and send a pull request. It may take a few weeks if I want to solve the problem myself.
@emem365, if you can solve the problem somehow, please send a pull request, and I'll merge your code to the repository. And If I can help somehow, please let me know.

best regards
--Mahdi

@mahdizakizadeh as I mentioned, I tried to but I can't clone the project. There seems to be error with a files path

[mzakizadeh]

@emem365 Is that a Git problem? I don't have any issue with cloning the project.

So nobody can fix it ? Even if we already know how to do it ?
