body: <p>I am using react-native-fetch-blob to download excel file and these files are stored inside app/documents folder which I am not able to open in iphone and I don't know the absolute path of the iphone's document folder to save the file there.</p>

  <pre><code>downloadFile(){
      const dirs = RNFetchBlob.fs.dirs;
      let context = this,
          userBarRelationId = context.state.userBarId;
      RNFetchBlob
    .config({
      fileCache : true,
      path : dirs.DocumentDir + '/excel.xlsx'
    })
    .fetch('GET', 'http://localhost:5000/getExcel/'+userBarRelationId, {
    })
    .then((res) =&gt; {
      console.log('The file saved to ', res.path(), res.data)
    })
    }
