Hey, can somebody help me to remove the bottom border on the tab view?

It's not border, it's acutally shadow,
You can remove using this:
<Tabview
...
style={{
shadowOffset: { height: 0, width: 0 },
shadowColor: 'transparent',
shadowOpacity: 0,
elevation: 0
}}
/>
If you use renderTabbar Props, Default Bottom Style is in TabBar Component. So you should pass props style in TabBarComponent.
<TabView
...
renderTabBar={props =>
<TabBar
style={{
shadowOffset: { height: 0, width: 0 },
shadowColor: 'transparent',
shadowOpacity: 0,
elevation: 0
}}
/>
}
/>
@springkjw thanks man it really worked for me. I was been looking for a whole day just for this. Now it has been solved. Thank you so much! And I think just elevation: 0 this one is enough to take out the tab bar shadow.
Was finding a solution for Android version and elevation: 0 has worked ✅
