  8. void onHttpError(
    1. HttpResponseError error
    )?,
  9. void onSslAuthError(
    1. SslAuthError request
    )?,
})

Constructs a NavigationDelegate.

onNavigationRequest: invoked when a navigation request is pending. onPageStarted: invoked when a page starts loading. onPageFinished: invoked when a page finishes loading. onProgress: invoked when page loading progress changes. onWebResourceError: invoked when a web resource loading error occurs. onUrlChange: invoked when the underlying web view changes to a new URL. onHttpAuthRequest: invoked when the web view is requesting authentication. onHttpError: invoked when an HTTP error status code is received. onSslAuthError: invoked when the web view receives a recoverable SSL error for a certificate. The host application must call either SslAuthError.cancel or SslAuthError.proceed.

Implementation

  void Function(String url)? onPageStarted,
  void Function(String url)? onPageFinished,
  void Function(int progress)? onProgress,
  void Function(WebResourceError error)? onWebResourceError,
  void Function(UrlChange change)? onUrlChange,
  void Function(HttpAuthRequest request)? onHttpAuthRequest,
  void Function(HttpResponseError error)? onHttpError,
  void Function(SslAuthError request)? onSslAuthError,
}) : this.fromPlatformCreationParams(
       const PlatformNavigationDelegateCreationParams(),
       onNavigationRequest: onNavigationRequest,
       onPageStarted: onPageStarted,
       onPageFinished: onPageFinished,
       onProgress: onProgress,
       onWebResourceError: onWebResourceError,
       onUrlChange: onUrlChange,
       onHttpAuthRequest: onHttpAuthRequest,
       onHttpError: onHttpError,
       onSslAuthError: onSslAuthError,
