PlatformNavigationDelegateCreationParams class

Object specifying creation parameters for creating a PlatformNavigationDelegate.

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

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

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

class AndroidNavigationDelegateCreationParams extends PlatformNavigationDelegateCreationParams {
  AndroidNavigationDelegateCreationParams._(
    // This parameter prevents breaking changes later.
    // ignore: avoid_unused_constructor_parameters
    PlatformNavigationDelegateCreationParams params, {
    this.filter,
  }) : super();

  factory AndroidNavigationDelegateCreationParams.fromPlatformNavigationDelegateCreationParams(
      PlatformNavigationDelegateCreationParams params, {
      String? filter,
  }) {
    return AndroidNavigationDelegateCreationParams._(params, filter: filter);
  }

  final String? filter;
}
