ng2-file-upload pass static data from input to onBeforeUploadItem

Question

I am new on angular and stuck while using one lib name ng2-file-upload.

I want to pass the static value from input value to onBeforeUploadItem function.

So here is my code.

`<div class="main" *ngFor="let att of attachment">
   {{att.name}}
   <div ng2FileDrop [uploader]="uploader" 
        (click)="fileInput2.click()">
      <span class="drop-text">Drop your
          document here, or <span class="browser-text">browse</span> 
      </span>
      <input type="file" #fileInput2 ng2FileSelect 
           [uploader]="uploader" style="display: none" />
   </div>
</div>`

Here I have 5 different attachments and parse them on html DOM and If I drop any file on any of the uploader then I also want to pass that attachment name along with file data.

ts file code.

`ngOnInit(): void {
   this.uploader = new FileUploader({
      url: url,
      autoUpload: true,
      authToken: `Bearer ${this.token}`,
      headers: [
        { name: "x-requested-with", value: "XMLHttpRequest" },
      ],
      maxFileSize: 2000,
    });
   this.uploader.onBeforeUploadItem = (item: FileItem) => {
      console.log("3", item);
      this.uploader.options.additionalParameter = {
        name: name, // here I want to pass that attachment name
        
      };
  `  };  
}

Any feedback will be helpful for me.
