Summary

#

RouteInformation.location and related APIs were deprecated in the favor of RouteInformation.uri.

Context

#

The RouteInformation needs the authority information to handle mobile deeplinks from different web domains. The uri field was added to RouteInformation that captures the entire deeplink information and route-related parameters were converted to the full Uri format. This led to deprecation of incompatible APIs.

Description of change

#
  • The RouteInformation.location was replaced by RouteInformation.uri.
  • The WidgetBindingObserver.didPushRoute was deprecated.
  • The location parameter of SystemNavigator.routeInformationUpdated was replaced by the newly added uri parameter.

Migration guide

#

Code before migration:

dart
const RouteInformation myRoute = RouteInformation(location: '/myroute');

Code after migration:

dart
final RouteInformation myRoute = RouteInformation(uri: Uri.parse('/myroute'));

Code before migration:

dart
final String myPath = myRoute.location;

Code after migration:

dart
final String myPath = myRoute.uri.path;

Code before migration:

dart
class MyObserverState extends State<MyWidget> with WidgetsBindingObserver {
  @override
  Future<bool> didPushRoute(String route) => _handleRoute(route);
}

Code after migration:

dart
class MyObserverState extends State<MyWidget> with WidgetsBindingObserver {
  @override
  Future<bool> didPushRouteInformation(RouteInformation routeInformation) => _handleRoute(
    Uri.decodeComponent(
      Uri(
        path: uri.path.isEmpty ? '/' : uri.path,
        queryParameters: uri.queryParametersAll.isEmpty ? null : uri.queryParametersAll,
        fragment: uri.fragment.isEmpty ? null : uri.fragment,
      ).toString(),
    )
  );
}

Code before migration:

dart
SystemNavigator.routeInformationUpdated(location: '/myLocation');

Code after migration:

dart
