Style the tab bar

[mordechaim]

I'd like to style the tab bar beyond just the background color (through the barTintColor) such as setting the height, adding a top border (to visually distinguish it from the content above), or add rounded corners.

Hey, unfortunately this is not possible to achieve across platforms.

Opt-ing in to using native tab bar brings in some constrains. If you want to have full customisability you can use JavaScript Tab Bar from React Navigation.
