In webview_platform, UnimplementedError: createPlatformNavigationDelegate is not implemented on the current platform.

[mosil]

Steps to reproduce

In my project I use the libreary webview_flutter_web 0.2.3+2.
When I impletement it in my project and run on chrome

I got the log: createPlatformNavigationDelegate is not implemented on the current platform.
So, I try implement it in main function

WebViewPlatform.instance = WebWebViewPlatform();
WebViewPlatform.instance!.createPlatformNavigationDelegate(PlatformNavigationDelegateCreationParams());

It's show same log.

Expected results

I wanted it to run normally in chrome or the browser on the mobile phone, and then monitor its onstart or onFinished during loadRequest.

Actual results

Get log:
DartError: UnimplementedError: createPlatformNavigationDelegate is not implemented on the current platform.

    )
      ..setPlatformNavigationDelegate(
        PlatformNavigationDelegate(
          const PlatformNavigationDelegateCreationParams(),
        )
          ..setOnPageStarted((url) {
            print("..........setOnPageStarted");
          })
          ..setOnProgress((progress) {
            print("..........setOnProgress");
          })
          ..setOnPageFinished(
            (url) {
              print("..........setOnPageFinished");
              // I need get something in url, in this stage
              });
            },
          ),
      )
      ..loadRequest(params);

...
// use PlatformWebView on  page widget, run it on chrome
PlatformWebViewWidget(PlatformWebViewWidgetCreationParams(controller: controller)).build(context)
