WebResourceError class

Error returned in WebView.onWebResourceError when a web resource loading error has occurred.

Platform specific implementations can add additional fields by extending this class.

{@tool sample} This example demonstrates how to extend the WebResourceError to provide additional platform specific parameters.

When extending WebResourceError additional parameters should always accept null or have a default value to prevent breaking changes.

class IOSWebResourceError extends WebResourceError {
  IOSWebResourceError._(WebResourceError error, {required this.domain})
      : super(
          errorCode: error.errorCode,
          description: error.description,
          errorType: error.errorType,
        );

  factory IOSWebResourceError.fromWebResourceError(
    WebResourceError error, {
    required String? domain,
  }) {
    return IOSWebResourceError._(error, domain: domain);
  }

  final String? domain;
}
