New project screen - when project location is changed, name isn't appended to the end

Not sure if this is a bug or intended.

I typed in project name, a default directory is shown with `new_project` as the last subdirectory:

Since I'm making a new project, I would expect that the directory is going to be made for me.

Default (non-Flutter) new project shows a line below of where the project will go:
