PlatformNavigationDelegateCreationParams class

Object specifying creation parameters for creating a PlatformNavigationDelegate.

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

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;
}
