TabBarController

API Reference: UI.TabBarController

TabBarController organizes and allows navigation between groups of Page_s that are related and navigation controller. Pages can be created and added on onPageCreate() function. TabBar indicator shows which bar is selected. Divider helps to seperate _TabBars on only Android.

onPageCreate on Android

To improve performance, the onPageCreate event is fired differently on Android and iOS. When the page is changed, iOS fires the method for the newly created page but Android fires the onPageCreate event for the second next page as well, calling the method for two pages at the same time.

AutoCapitalize

Known issue; In Android, if lower-case text in the tab items required, the autoCapitalize property must be assigned each time when the tab item's appearance updated.
