When asking to add a platform to a project, it should use flutter create --empty #5494
Description
Describe the bug
When I run a project on a platform that isn't currently supported by the project, the extension asks me to add the desired platforms, which makes sense.
But when it adds it, it uses the flutter create --platform=linux command, which not only adds the platform, it also creates things like a test/main_test.dart, which are unrelated to adding a platform, and are confusing if you already have a project with a main.dart, but no test called main_test.dart, since now you have a test that fails if you run it, and you have no idea where that came from.
The flutter create command has an --empty argument which limits the creation of new files and simplifies the files it does create to the minimum.
Adding platforms should use that.
The --empty arg should probably write fewer things too (it currently writes a plain README.md which is unnecessary), but that's not an extension bug.
To Reproduce
Steps to reproduce the behavior:
- Create a project that has no platform directories.
- Try to run the main.
- When asked, say you want to add the desktop platform you're running on.
- Notice that there is a test/test_main.dart file.
Expected behavior
Adding a platform should only add a platform, not create extra files.
