[desktop_webview_window] Can't open URL about:srcdoc on macOS

Can't open URL about:srcdoc on macOS...
Is there any reason why the URL "about" is not on the scheme guard block?
Thank you.

On WebViewLayoutController.swift:

extension WebViewLayoutController: WKNavigationDelegate {
  func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
    guard let url = navigationAction.request.url else {
      decisionHandler(.cancel)
      return
    }

    guard ["http", "https", "file"].contains(url.scheme?.lowercased() ?? "") else {
      decisionHandler(.cancel)
      return
    }

    methodChannel.invokeMethod("onUrlRequested", arguments: [
      "id": viewId,
      "url": url.absoluteString,
    ] as [String: Any])

    decisionHandler(.allow)
  }

Version:

• Flutter Version: v3.24.0
• OS: macOS
• plugin: desktop_webview_window: 0.2.3

Start in the macOS WebViewLayoutController.swift WKNavigationDelegate method shown in the issue and inspect how navigation URL schemes are filtered. Reproduce the about:srcdoc navigation on macOS, then verify that the intended URL opens without breaking the existing http, https, and file handling.
