Hi, I was looking to trying out Redux in Flutter. So I was creating a new Flutter project was installing this package and got the following error.

[flutter_redux] flutter packages get
Running "flutter packages get" in flutter_redux...
Error on line 19, column 3 of pubspec.yaml: A package may not list itself as a dependency.
  flutter_redux: ^0.5.2
  ^^^^^^^^^^^^^
pub get failed (65)
exit code 65

I was looking for solution, but didn't seems to find any with Google. Does anyone have the same problem?

Thanks

I deleted the project and started a new project and it somehow it just magically work. I'll leave it to the mod to see if the ticket should be closed or not.

Thanks

Hrm -- truly odd! It looks to me like you created your own project called "flutter_redux" and then tried to import the flutter_redux package into that project.

The problem: At that point, Dart will think your package is called flutter_redux and won't be able to import the third-party library.

Could that be the problem?

[panuavakul]

Thanks for your reply, that seems to be the problem.
That was really stupid of me.
Since this is solved, I will just close it. Thanks again.

It makes no sense that you can't name projects the same as the libraries' names. Why would it be dumb calling your app image_picker and then not being able to use a library called image_picker in it because someone already used up the name for the name of a library? That makes no sense. There's going to be thousands of libraries, are you telling me all those names will then be taken and you wouldn't be able to call your app that name if you need that resource that has the same name? That just makes no sense
