Looks like VSCode has failed to correctly check out dependencies. I'd shutdown VSCode, confirm the code works from the command line with flutter run and then open up VSCode again on the specific step you are interested in.

I've found VSCode can be a bit iffy with checkouts that contain multiple flutter projects.

/cc @DanTup this might be of interest to you. =)

I'm not familiar with the project mentioned here - is there a repo/document I can try out to see if I can repro?

Generally when opening a new project that has no .packages file, there should be a prompt to run pub get like this:

VS Code will collapse these notifications after some time (10 seconds?) though (something we can't control) so if you miss it, you'll have issues like this until you manually run Dart: Get Packages from the VS Code Command prompt or click the bell icon in the bottom right corner and run it from the collapsed notification.

If you modify the pubspec.yaml, pub get should be run automatically by default.

If you see situations where any of this might not be working reliably, do file issues at https://github.com/Dart-Code/Dart-Code with as much info as you can that might help reproduce it. Thanks!

@DanTup the repository in question is https://github.com/googlecodelabs/flutter-cupertino-store

I just tried it myself against VSCode Version: 1.46.1 with Flutter 3.11.0 and it indeed shows the Get packages pop up. The various projects show as red until flutter pub get has been run by VSCode in each step sub directory.

@acendre can you replicate?

Hello !
Thanks for answering so fast. I did what you suggested but it didn't work.

I will detail what I have and what I did to have this.

Sorry if I'm not that familiar with Git process but I'm new to it.
VScode Version: 1.46.1
Where did you see Flutter version ? It's recent

I just downloaded the project, put it in my developement repository where flutter repo is. Then launch VScode and open the project cupertino_store. Then I did flutter pub get or/and package get. It didn't change errors that much. (PS : I already achieve to create the app "start_up").

@acendre if you run flutter analyze from the terminal in the same folder, do you see the same errors reported?

Yes exactly the same ...

flutter pub get and packages get are the same command ?

Yep, they're the same command. For the project (or one of the projects) that are showing errors like this, is there a .packages file in the root of the project? Does it contain a line for flutter_test?

Yes, there is file .packages :

@acendre can you check you have this in your pubspec.yaml?

dev_dependencies:
  flutter_test:
    sdk: flutter

I think it's probably missing. It should be in the default pubpsec.yaml created by the Flutter: New Project command.

Ok thank you, it's good now. Does it exist processes to follow into avoiding that manipulation when we open an existing project ?

@acendre I'm not sure how you ended up without that dependency. It's included automatically when you create a project with flutter create or Flutter: New Project. Is it possible you accidentally removed it while modifying the pubspec.yaml? Or did you build the project manually from following some instructions? (in which case, maybe they are missing this?).

Closing this out as the debugging conversation appears to have gone stale.
