WebViewX(
        initialContent: '',
        javascriptMode: JavascriptMode.unrestricted,
        ignoreAllGestures: false,
        onWebViewCreated: (_controller) {
          webviewController = _controller;
          _loadHtmlFromAssets();
        },
        onPageFinished: (strURL) {
          setState(() {
            _isLoading = false;
          });
        },
        height: MediaQuery.of(context).size.height,
        width: MediaQuery.of(context).size.width,
      ),

I created a WebViewX and using Javascript to play some audios and set image source on the webview. It worked on flutter web version, but not on android. How do I make it work?

onSuccess: function(result) {
                document.getElementById("imgres").src = "https://animagesourceslink.com/static/anim_success.gif"
                document.getElementById('txtdariorangberseragam').innerHTML  = "Press back to continue"
                document.getElementById('audioSuccess').play();
              },
