TabContoller inside pageview causes indicator to change index.

[dickverweij]

Inside a PageIndicator I have a PageView which hosts a DefaultTabcontroller with 2 tabs.

If i change the active tab index inside the page a ScrollNotification with depth = 1 will be send to the _onScroll method in the PageIndicator causing incorrect behavior (cause the tab is changed not the page in the PageView)

if i change the index of the PageView a ScrollNotificaiton with depth = 0 will be send to the _onScroll method in the PageIndicator

Typically a ScrollNotification Listener should respond to a scrollnotification with depth of only 0,

could this be changed?
