Request a collapsible left navigation menu on the online Flutter documentation

[pstricks-fans]

When reading Flutter documentation (in flutter.io, flutter.dev, etc), the left navigation menu is really distracting. We can automatically collapse it by zooming in (ctrl+mouse scroll in Windows). Unfortunately, this action makes the font size is too huge so forcing us to horizontally scroll the code snippet provided on the screen. It is very unpleasant for on screen reading.

If you don't mind please kindly provide us with a button to manually collapse the distracting left navigation menu (and the upper bar with twitter, youtube and git icons, occasional sub menu on the right).

And/or a collapsible right navigation menu. Having both expanded seems like a waste of space and makes it difficult to read the code on smaller screens.
