Unable to run the app

[TanujChaniyari07]

I am getting this error 66 - Could not find a file named "pubspec.yaml". Even when it is present. I am a beginner in flutter so could you please help me out.

Run cd app to navigate the app directory before running the flutter command you are trying to use.
It appears you are running the command in the root directory and the pubspec.yaml file is located at app/pubspec.yaml and not at the root.

This what I get when I open the folder and click on get packages

The Nima-Flutter project is on another repo https://github.com/2d-inc/Nima-Flutter and is added as a submodule to this project.
I believe that the Nima-Flutter directory you have is currently empty (please confirm). You need to run the following command to get it on your machine

git submodule init
git submodule update

The Usage section of the README.md file includes the above command https://github.com/2d-inc/HistoryOfEverything#usage

You can take a look at the instructions there if you've not seen it already.

Sorry about that. I don't have insight into why it might be taking long. I would do a fresh clone of this repo and try to set it up to see if I might run into the same issue.

So when did a fresh clone this what I am getting

Delete the .packages file. Then run the pub get command again, flutter will generate a new one with the correct/up-to-date path.

Delete the .packages file. Then run the pub get command again, flutter will generate a new one with the correct/up-to-date path.

Warning! This package referenced a Flutter repository via the .packages file that is no longer available. The repository from which the 'flutter' tool is currently executing will be used instead.
running Flutter tool: C:\Users\Tanuj Chaniyari\flutter
previous reference : C:\Flutter\HistoryOfEverything\dependencies\Nima-Flutter\Users\luigirosso\Projects\flutter
This can happen if you deleted or moved your copy of the Flutter repository, or if it was on a volume that is no longer mounted or has been mounted at a different location. Please check your system path to verify that you are running the expected version (run 'flutter --version' to see which flutter is on your path).

Running "flutter pub get" in Nima-Flutter... 4.3s

The screenshot that I sent before contains this error

[TanujChaniyari07]

I deleted .packages file and ran the command but still, I am getting some errors Please help

[Alameen688]

I see you are running the flutter pub get command in the root directory. cd app to navigate to app directory then flutter pub get to get packages.

Did that but still all files show errors

[Alameen688]

Did the command run successfully? And what do you mean by "all files show errors"?
Do you mean the red underline in VS code when referenced packages are not installed? If pub get command is still running, you might need to wait for it to complete before those lines diappear.

Yeah it did run successfully here's a screenshot

[Alameen688]

I see it installed some packages and didn't install some. For example, the timeline package.
Go ahead and delete the both .packages pubspec.lock lock file and do the package get again

[Alameen688]

It seems it was successful. The timeline import is no longer underlined in red.
You can restart VS Code so that it will reflect for all the other files.
