Button Margin Right or Margin End Not working

[harshalone]

I have added a simple Done button and want to give it a margin 30 but its not working

My Code:

<Button style={styles(colors).done}
          title={'Done'} 
          buttonStyle={{
            marginEnd: 30,
          }}
          containerViewStyle={{
            marginEnd: 30,
          }}    
        /> 

followed the example code

I don't know what's wrong, but I'm pretty sure there is another way to achieve the desired layout. :)
