<RefreshableWrapper
	Loader={() => (
		<LottieView
			style={styles.lottie}
			autoPlay
			source={require('./assets/lottie/refresh.json')}
		/>
	)}
	isLoading={isLoading}
	onRefresh={() => {
		refreshHandler();
	}}
>
	<AnimatedFlatlist />
</RefreshableWrapper>

-- Example

import { StatusBar } from 'expo-status-bar';
import React, { useState } from 'react';
import { StyleSheet, Text, View, FlatList, Dimensions } from 'react-native';
import Animated from 'react-native-reanimated';
import RefreshableWrapper from 'react-native-fresh-refresh';
import LottieView from 'lottie-react-native';

const AnimatedFlatlist = Animated.createAnimatedComponent(FlatList);
const data = ['1', '2', '3', '4', '5', '6'];
const { width } = Dimensions.get('screen');

const EmptyComponent = (props) => {
	return (
		<View>
			<Text>LIST EMPTY COMPONENT</Text>
		</View>
	);
};
const ListItem = (props) => {
	return (
		<View style={{ height: 200 }}>
			<Text>LIST Item COMPONENT</Text>
			<Text> {props.item}</Text>
		</View>
	);
};

export default function App() {
	const [isLoading, setIsLoading] = useState(false);
	const [listData, setListData] = useState([]);

	const refreshSimulationHandler = () => {
		setListData([]);
		setIsLoading(true);
		setTimeout(async () => {
			setListData(data);
			setIsLoading(false);
		}, 1500);
	};

	return (
		<View style={styles.container}>
			<StatusBar style='auto' />
			<View style={styles.header}></View>
			<RefreshableWrapper
				Loader={() => (
					<LottieView
						style={styles.lottie}
						autoPlay
						source={require('./assets/lottie/refresh.json')}
					/>
				)}
				isLoading={isLoading}
				onRefresh={() => {
					refreshSimulationHandler();
				}}
				EmptyComponent={EmptyComponent}
			>
				<AnimatedFlatlist
					data={listData}
					bounces={false}
					keyExtractor={(item) => item}
					renderItem={({ item }) => {
						return <ListItem item={item} />;
					}}
					style={styles.scrollList}
					contentContainerStyle={styles.contenContainer}
					showsVerticalScrollIndicator={false}
					scrollEventThrottle={16}
					ListEmptyComponent={() => <EmptyComponent />}
				/>
			</RefreshableWrapper>
		</View>
	);
}

const styles = StyleSheet.create({
	container: {
		flex: 1,
		backgroundColor: '#fff',
		alignItems: 'center',
		justifyContent: 'center',
	},
	header: { width, height: 100, backgroundColor: 'grey' },
	contenContainer: {
		paddingVertical: 10,
		paddingHorizontal: 16,
		paddingBottom: 100,
		alignItems: 'center',
	},
	lottie: {
		width: 50,
		height: 50,
	},
	scrollList: { width, paddingTop: 20 },
});
