React-native footer within scrollview - react-native

Question

As I wanted to create a footer, I followed the advices saying I had to put a scrollview within a view to make it right.
Well, that's almost perfect but could you help me with one detail ? in the red circle of the picture, we can see that my view is visible. I would like to make the top of it disappear. I tried marginTop: 0 and paddingTop: 0, but it didn't work.
Thanks for any help !
My code for this page :
import React, { Component } from "react";

import Footer from "../../Components/Footer/Footer";
import { Header } from "react-native-elements";
import MenuButton from "../../Drawer/MenuButton";
export default class Welcome extends React.Component {
render() {
return (
<View style={styles.footer}>
<Header
rightComponent={<MenuButton navigation={this.props.navigation} />}
centerComponent={{ text: 'Bienvenue au Gavroche', style: {fontFamily: "Parisienne", fontSize: 24, color: '#fff' } }}
containerStyle={{
backgroundColor: "#013243",
justifyContent: "space-around"
}}
