i have check a lot of posts related to Tab icon changes in NS
I know we can implement tab active color change by
<TabView :selectedIndex="selectedIndex" iosIconRenderingMode="alwaysTemplate" selectedTabTextColor="#FF8000">
There is also suggestion by NickIliev, however it doesn’t work
<TabViewItem title="Connections" iconSource=" selectedIndex == 1 ? '~/assets/images/footer-icons/profile.png' : '~/assets/images/footer-icons/profile-active.png'" :onPress="toggleTab2">
However, such solution is just an overlay color change but cannot change the source of icon, i found such problem already for a year, it is something need to code by us or NativeScript not support yet.
