How do I put space between each element of a list? – React native

I have an appendable list of View and I want to add space to between each element of my list.

Here is an overview of my code –

    list = []
    function func(){
        button(){
            list.append(
                 <View style = {1}> 
                      ...
                      ...
                      ...
                 <View>
             )
        }

        return(
            <View>
                 <View>
                      <Text onPress = {() => button()}> + </Text> 
                 <View>

                 <ScrollView style = {3}>
                      <View style = {2}>
                          {list}
                      <View>
                 <ScrollView>
            <View>
        ) 
}

My app currently looks something like this –

My question is which CSS component should I style – {1}, {2} or {3}?

Here is my actual code –

import React, { Component, useState, useEffect } from "react";
import {
  View, 
  Text,
  StyleSheet,
  TextInput, 
  ScrollView
} from 'react-native';

function WeatherApp(){
    const [data, setData] = useState([])
    const[i, setI] = useState(0)
    
    const dates = [1, 2, 3, 4, 5, 6, 7, 8, 9]
    const temperatures = [20, 21, 26, 19, 30, 32, 23, 22, 24]
    const cities = ['LA', 'SAN', 'SFO', 'LGA', 'HND', 'KIX', 'DEN', 'MUC', 'BOM']

    const buttonPressed = () => {
        if(i < 9){
            data.push(
                <View style = {styles.weatherBoard}>
                    <Text key = {dates[i]} style = {styles.date}>{dates[i]}</Text>
                    <Text key = {temperatures[i]} style = {styles.temperature}>{temperatures[i]}</Text>
                    <Text key = {cities[i]} style = {styles.cityName}>{cities[i]}</Text>
                </View>
            )
            setData(data)
            setI(i => i + 1)
        }
    }
    useEffect(()=>{}, [i])
    return(
        <View style = {styles.appBackground}>
            <View style = {styles.searchBar}>
                <TextInput style = {styles.searchText} placeholder = "Search City"></TextInput>
                <Text onPress={() => buttonPressed()} style = {styles.addButton}>+</Text>
            </View>
            
            {/* ScrollView can only have one view in it */}
            <ScrollView style = {styles.weatherPanel} >
                <View>
                    {data}
                </View>
            </ScrollView>

        </View>
    )
}

Here is my css file –

const styles = StyleSheet.create({
    appBackground:{
        flex: 1,
        backgroundColor: 'black', 
        flexDirection: 'column'
    },

    searchBar:{
        flex: 0.1,
        flexDirection: 'row',
        backgroundColor: 'white', 
        fontSize: 25
    },
    searchText:{
        flex: 8,
        borderWidth: 1
    },
    addButton:{
        flex: 2,
        textAlign: 'center',
        fontSize: 40,
        borderWidth: 1
    },
    // Place where all cities' weather are shown
    weatherPanel:{
        flex: 0.9,
        flexDirection: 'column',
        padding: 15
    },

    // Style for each city 
    weatherBoard:{
        flex: 9, 
        backgroundColor: 'blue',
        borderRadius: 10,
        padding: 10
    },

    // Temorary styles - 
    date: {
        fontSize: 20,
        color: 'white'
    },
    temperature:{
        fontSize: 30
    },
    cityName:{
        fontSize: 30
    }
})
