expo-asset useAssets hook returns undefined while there is cached image on the disk

When internet access is on, useAssets returns the localUri as expected. But after going offline, it returns undefined. Even the cached file still exists in the cache folder, it does not reference it. The code is below:

import React from "react";
import { useAssets } from "expo-asset";
import { Image, View } from "react-native";

export default function Avatar({ imageUrl}) {
  const [assets, error] = useAssets([imageUrl]);

  return (
    <View style={[styles.avatar, style]}>
      <Image
        source={{
          uri: assets[0].localUri
        }}
      />
    </View>
  );
}

So I want to access downloaded and cached images offline with useAssets hook but it seems that expo-assets has not such feature, isn't it?
