How to use the react-native-background-upload.startUpload function in react-native-background-upload

Upload.getFileInfo(opts.path).then((metadata) => {
      const options = Object.assign({
        method: 'POST',
        headers: {
          'content-type': metadata.mimeType // server requires a content-type header
        }
      }, opts)

      Upload.startUpload(options).then((uploadId) => {
        console.log(`Upload started with options: ${JSON.stringify(options)}`)
        this.setState({ uploadId, progress: 0 })
        Upload.addListener('progress', uploadId, (data) => {
          this.handleProgress(+data.progress)
          console.log(`Progress: ${data.progress}%`)
        })
        Upload.addListener('error', uploadId, (data) => {
          console.log(`Error: ${data.error}%`)
        })
        Upload.addListener('completed', uploadId, (data) => {
          console.log('Completed!')
        })
      }).catch(function(err) {
        this.setState({ uploadId: null, progress: null })
        console.log('Upload error!', err)
      })
