Unable to execute the newly created project using vgv_cli.

[NaagAlgates]

Description I was able to successfully create a project using vgv cli. After opening the created project in Vs Code, I get 216 errors.

Steps To Reproduce

1. Create a project using cli
2. open it in vs code

Expected Behavior The expected behaviour is to get an executable project without any errors and in an executable condition.

Screenshots

Additional Context When I tried to run the pug upgrade command, I get the following message

[my_first_project_using_vgv_cli] flutter pub upgrade
Running "flutter pub upgrade" in my_first_project_using_vgv_cli...     
The current Dart SDK version is 2.10.5.

Because my_first_project_using_vgv_cli requires SDK version >=2.12.0-0 <3.0.0, version solving failed.

Please let me know what I'm missing here.

Hi @NaagAlgates 👋 Thanks for opening an issue!

Because the generated project uses null safety, please make sure to use the beta channel:

$ flutter channel beta
$ flutter upgrade

Hope that helps 👍

@NaagAlgates we updated the documentation to specify that the generated code requires the beta channel due to null safety. If after switching channels you're still having trouble let us know and we're happy to help 👍
