          ->afterStateUpdated(function (?string $state, Set $set, Get $get, TemporaryUploadedFile $file) {
              dd($file->getSize(), $file->dimensions());
          }),

->getUploadedFileNameForStorageUsing(function (Set $set, Get $get, TemporaryUploadedFile $file){
    $fileSize = $file->getSize(); 
    $fileDimensions = $file->dimensions();

    $set('size', round($fileSize / 1024, 2));
    $set('width', $fileDimensions[0]);
    $set('height', $fileDimensions[1]);
    
    $hash = str()->random(30);
    $timestamp = now()->timestamp;  
    $extension = '.' . $file->getClientOriginalExtension();

    return $hash.$timestamp.$extension;
