FormData is null

Hi, I need help in image upload with vuejs and Laravel. I am using this package to upload image https://github.com/lekhang2512/vue-upload-multiple-image

<template>
<div>

    <vue-upload-multiple-image
      @upload-success="uploadImageSuccess"
      @before-remove="beforeRemove"
      @edit-image="editImage"
      @data-change="dataChange"
      ></vue-upload-multiple-image>
</div>
</template>

methods:{
        
       
    uploadImageSuccess(formData, index, fileList) {
        //console.log('data', formData, index, fileList)
    

axios.post('/images',fileList,{headers: {
        'Content-Type': 'multipart/form-data' }
         }).then(response => {
            console.log(response);
    })},
    beforeRemove (index, done, fileList) {
      console.log('index', index, fileList)
      var r = confirm("remove image")
      if (r == true) {
        done()
      } else {
      }
    },
    editImage (formData, index, fileList) {
      console.log('edit data', formData, index, fileList)
    },
    dataChange (data) {
      console.log(data)
    }

controller:

public function Images(Request $request){
       return($request->formData);
	
     
    }

I want to get filename and save in file in public directory and image in db But I am getting null form data.
