urlLoading method

  1. @override
void urlLoading(
  1. WebView webView,
  2. String url
)

When a URL is about to be loaded in the current WebView.

If a WebViewClient is not provided, by default WebView will ask Activity Manager to choose the proper handler for the URL. If a WebViewClient is provided, setting shouldOverrideUrlLoading to true causes the current WebView to abort loading the URL, while returning false causes the WebView to continue loading the URL as usual.

Implementation

@override
void urlLoading(android_webview.WebView webView, String url) {
  if (!handlesNavigation) {
    return;
  }

  final FutureOr<bool> returnValue = onNavigationRequestCallback!(
    url: url,
    isForMainFrame: true,
  );

  if (returnValue is bool && returnValue) {
    loadUrl!(url, <String, String>{});
  } else if (returnValue is Future<bool>) {
    returnValue.then((bool shouldLoadUrl) {
      if (shouldLoadUrl) {
        loadUrl!(url, <String, String>{});
      }
    });
  }
}
