file-upload - 如何将额外的参数传递给上传按钮组件？验证

Question

我正在使用vuetify-upload-button组件来上传文件。fileChangedCallback使用仅加载文件的函数回调。但是，我需要有额外的参数才能做出逻辑。是否可以向此函数传递额外的参数？

这是我的代码：

v-flex.listFilesUpload(v-for="(file, index) in attachments" :key="index")
  p
    span
      | {{ index + 1 }}
  .btns-upload-download
    upload-btn(title="File" :fileChangedCallback="fileChanged" color="default")

import UploadButton from 'vuetify-upload-button'

export default {
  [..]
  methods: {
    fileChanged (file) {
      // Here I need my other variable file because it have the filename.
      if (file) {
        formData.append('filenames[]', file)
      }
    },
    components: {
      'upload-btn': UploadButton
    }
  }
}
