javascript - Ajax to php retrieving formdata ← (PHP, Laravel, JavaScript, Vue.js)

one text

I'm sending my files through vue.js to my laravel backend but I'm not able to retrieve the data correctly.

Vue.js :

<b-form-file
    v-model="files"
    :state="Boolean(files)"
    placeholder="Choisissez un fichier..."
    drop-placeholder="Glisser ici..."
    multiple
    accept=".jpg, .png"
    class="textOverflow"
    name="file[]"
></b-form-file> 

Ajax :

onSubmit(){
    let formData = new FormData();
    for( var i = 0; i < this.files.length; i++ ){

        let file = this.files[i];

        formData.append("filePos: "+ i, file, this.id);
    }

    axios.post('/pictures', formData, 
    {headers: {'Content-Type': 'multipart/form-data'} })
    .then((res) => { 
        console.log(res);
    })
    .catch((err) => {
        console.log(err);
    });
} 

Laravel php :

public function store(Request $request)
{
    $images = $request->all();

    info($images);
}

So this gives me :

[2020-04-26 15:40:48] local.INFO: array (
  'filePos:_0' => 
  Illuminate\Http\UploadedFile::__set_state(array(
     'test' => false,
     'originalName' => '25',
     'mimeType' => 'image/png',
     'error' => 0,
     'hashName' => NULL,
  )),
)  
[2020-04-26 15:40:50] local.INFO: array (
  'filePos:_0' => 
  Illuminate\Http\UploadedFile::__set_state(array(
     'test' => false,
     'originalName' => '25',
     'mimeType' => 'image/png',
     'error' => 0,
     'hashName' => NULL,
  )),
) 

Which is perfect, but I can't retrieve specific data like if I just want the originalName and do ->request('name'), I can the weird chain of characters as if I wasn't the correct encoding.

Does someone know how to retrieve specific information for separating the images, manipulate them and so.

Thanks for reading

Edit :

If I use dd instead of info :

array:1 [
  "filePos:_0" => Illuminate\Http\UploadedFile {#343
    -test: false
    -originalName: "25"
    -mimeType: "image/png"
