I am trying to implement a SrollView in my project however for some reason when I try to scroll through all the elements inside it, it springs back to the top of the ScrollView. I've looked around and some other questions were resolved by adding flex:1 to the ScrollView, however when I try that the entire ScrollView goes off screen. I've tried to add position:'absolute' to the ScrollView however that only leads to the scrollView not moving anymore
I've also tried experimenting with <KeyboardAwareScrollView> however the screen doesn't seem to adjust to the Input.
Here is my code:
import React from "react";
import {
View,
Dimensions,
Platform,
ActivityIndicator,
Alert,
Image,
KeyboardAvoidingView,
TouchableHighlight,
Keyboard
} from "react-native";
import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'
import { Form, Item, Input, Label, Button, Text, Picker } from "native-base";
import * as firebase from "firebase";
import { ScrollView } from "react-native-gesture-handler";
import { LinearGradient, ImagePicker, Permissions } from "expo";
import Modal from "react-native-modal";
import uuid from "uuid";
import axios from "axios";
<View style={{borderBottomLeftRadius:20, borderBottomRightRadius:20, marginTop:20}}>
<TouchableHighlight onPress={this.toggleModal} underlayColor="white">
<Image source={{ uri: this.state.imageUrl }} style={{ width: SCREEN_WIDTH, height: SCREEN_HEIGHT/3, borderRadius: 20, marginBottom:20 }}/>
</TouchableHighlight>
</View>
}
{!this.state.loading ? (
