I have a nav drawer with a few buttons. When i click or tap a button wothin the nav drawer it often doesnt fire its click event. I have hooked them up to some custom method, but all that method does is close the nav drawer, change the text held within the app bar and change screen on a screen view. I often tap or click a nav drawer button, see the ripple effect but then nothing else happens. The mav drawer stays open etc. I saw the aame happen when the buttons were hooked up to the default close nav drawer method before i changed it.
