react-native-0.51-save-image-from-app-to-local.js

import RNFetchBlob from 'react-native-fetch-blob';
import RNFS from'react-native-fs';

  let dirs = RNFetchBlob.fs.dirs
  const file_path = dirs.DCIMDir + '/' + 'wechat.jpg';
  RNFS.copyFileAssets('wechat.jpg', file_path)
  .then(() => {
    RNFetchBlob.fs.scanFile([{ path: file_path }])
  })
  .catch((error) => console.log(error));

I hope it save your time.
I spend 30 minute on this. it's ridiculous

if you want test if file exist under /android/app/src/main/assets/

import RNFS from'react-native-fs';

RNFS.existsAssets('wechat.jpg').then((result) => console.log(result));
