React Native elements searchbar border lines not clearing

For anyone else looking to remove those borders try setting the width of every border separately:

containerStyle={{
    borderWidth: 0, //no effect
    borderTopWidth: 0, //works
    borderBottomWidth: 0, //works
}}

in new version of react native elements

containerStyle={{
    backgroundColor:"#FBFBFB",
    borderBottomColor: 'transparent',
    borderTopColor: 'transparent'
}}

Use borderBottomColor and borderTopColor as transparent with searchcontainer

searchcontainer: {
 backgroundColor: 'white',
 borderWidth: 0, //no effect
 shadowColor: 'white', //no effect
 borderBottomColor: 'transparent',
 borderTopColor: 'transparent'
}

Hope this will help
