Access user in AppServiceProvider?

I need to be able to pass data to all views when the user is logged in.

Here is what my AppServiceProvider currently looks like:

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        if (Auth::check())
        {
            View::share('key', 'value');
        }
    }
}

However, the data is never passed to the view because I can't use Auth (for some reason) in AppServiceProvider so the if statement condition is never met.

Following a previous solution I found, I tried doing this:

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        View::composer('*', function ($view)
        {
            if (Auth::check())
            {
                View::share('key', 'value');
            }
        }
    }
}

This worked, but the problem is that the closure is called whenever a view is rendered. For example, if my blade template includes 3 other blade templates (which it does), then the closure above will be called 4 times. Explained further here.

So how can I access the user correctly in AppServiceProvider?
