fix: dart template should not rely on `flutter` commands

[Mr.Minnu]

Description
I'm trying to create a cli using very_good_cli, but I noticed that it uses Flutter to get packages. But Why? We can actually use Dart and Flutter according to the project types, right?

Steps To Reproduce

1. Install cli
2. create a dart_cli project
3. Observe the logs

Expected Behavior
Should Ideally, use dart cli to get package dependencies

I believe you're correct, only dart pub get should be needed.
