'flutter webview disallowed user agent

I am trying to openning sign-in google with webview in flutter application. I installed flutter_inappwebview: ^3.1.0 and this is my code:

child: InAppWebView(
  initialUrl: url.toString(),
  initialHeaders: {},
  initialOptions: InAppWebViewGroupOptions(
      crossPlatform: InAppWebViewOptions(
    userAgent:
        "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36",
    debuggingEnabled: true,
  )),

but when i open google sin in page i got this error:

change userAgent to random like -> userAgent: "random". works perfectly! but then it will most likely low end mobile interface for google page. that's the only drawback. else works perfectly fine !

Using webview_flutter package you can fix the problem by adding userAgent: 'random', in the web view constructor. So, it will look like this:

WebView(
       initialUrl: 'https://abdulrazakzakieh.com/',
       userAgent: 'random',
)
