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.

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;
}
