Facebook 像素在 Flutter Web

Question

I have a website made in flutter web that works very well I recently decided to insert a facebook tool the facebook Pixel I used the code provided by facebook to insert on my website

我编辑了 index.html 文件并将标签插入到头部

<!-- Facebook Pixel Code -->
  <script>
  var ran = false;
    !function(f,b,e,v,n,t,s)
    {if(f.fbq)return;n=f.fbq=function(){n.callMethod?
    n.callMethod.apply(n,arguments):n.queue.push(arguments)};
    if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
    n.queue=[];t=b.createElement(e);t.async=!0;
    t.src=v;s=b.getElementsByTagName(e)[0];
    s.parentNode.insertBefore(t,s)}(window,document,'script',
    'https://connect.facebook.net/en_US/fbevents.js');

      if (rotated == false) {
    rotated = true;
    fbq('init', '########');
   }


    console.log(fbq);
    fbq('track', 'PageView');



</script>x
  <noscript>
    <img height="1" width="1"
         src="https://www.facebook.com/tr?id=########&ev=PageView
&noscript=1"/>
  </noscript>
  <!-- End Facebook Pixel Code -->

现在我正在使用扩展程序（Facebook Pixel Helper）检查安装是否正确并收到以下消息“Facebook 像素在此 web 页面上激活了 2 次，这可能会导致您的事件跟踪出现错误。”

在使用 flutter 时，有人知道如何解决这个问题吗？

如果可以在 flutter web 站点中使用此工具
