Drawbacks of not having a global Flutter version?

[Isuru-Nanayakkara]

Hi, I'm quite new to fvm and Flutter as a whole and I have a question regarding the global configuration. First I'll briefly explain the ideal development environment that I'm aiming for.

I don't want a globally installed Flutter version. I work with multiple Flutter projects, all using different Flutter versions. So I simply set project-specific Flutter versions using fvm. Therefore, I don't see the use of having a default, global Flutter version.

However, the official docs of fvm states the following:

We recommend installing the Flutter SDK globally using the official installation guide here. This will be the main version of Flutter across your machine.

Can I know why this is recommended? Is it required to have a default, global Flutter version for fvm to function without problems? Are there any drawbacks with my default-less approach?
