So, Go to resources/views and create file-upload.blade.php and update the following code into it:

<!DOCTYPE html>
<html>
<head>
  <title>Laravel 10 File Upload Example - Tutsmake.com</title>

  <meta name="csrf-token" content="{{ csrf_token() }}">

  <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">


</head>
<body>

<div class="container mt-4">

  <h2 class="text-center">File Upload in Laravel 10 - Tutsmake.com</h2>

      <form method="POST" enctype="multipart/form-data" id="upload-file" action="{{ url('store') }}" >
                
          <div class="row">

              <div class="col-md-12">
                  <div class="form-group">
                      <input type="file" name="file" placeholder="Choose file" id="file">
                        @error('file')
                        <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
                        @enderror
                  </div>
              </div>
                
              <div class="col-md-12">
                  <button type="submit" class="btn btn-primary" id="submit">Submit</button>
              </div>
          </div>     
      </form>
</div>

</div>  
</body>
</html>

  @error('file')
  <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
  @enderror
