Update clear button example

update clear button with wrong example on 'Simple app state management' #2906

Hi @aloksingh3112, well spotted! Thanks for the contribution!

This sample excerpt is tested. You'll find the source over in https://github.com/flutter/website/blob/master/examples/state_mgmt/simple/lib/src/performance.dart#L101. Could you please update also that line (in a way that still passes tests)? That probably means adding removeAll() to CartModel, or calling something else (.items.clear()?).

More info about how sample excerpts are tested can be found over at https://github.com/dart-lang/site-shared/blob/master/doc/examples.md.
