  • Example lib/core/config/push_notifications_config.dart

    final FirePushNotificationsConfig pushNotificationsConfig = FirePushNotificationsConfig(
      registerDeviceTokenApiEndpoint: (params) {
        return Uri.parse(EnvironmentConfig.api_url + ApiEndpoints.devices());
      },
      removeDeviceTokenApiEndpoint: (params) {
        return Uri.parse(EnvironmentConfig.api_url + ApiEndpoints.devices());
      },
      removeDeviceRequestMapper: (request, info, params) {
        if (params?.containsKey("authToken") ?? false) {
          request.headers.addAll({
            "Authorization": params!["authToken"],
          });
          return request;
        }
        return request;
      },
    );
    

• Create a wrapper container to setup some config and have better control

  • Example lib/core/presentation/containers/app_push_notifications_container.dart

    import 'package:flutter/material.dart';
    import 'package:flutter_bloc/flutter_bloc.dart';
    import 'package:flutter_gb_app_notifications/application/bloc/bloc.dart';
    import 'package:flutter_gb_authentication_basic/flutter_gb_authentication_basic.dart';
    import 'package:flutter_gb_fire_push_notifications/flutter_gb_fire_push_notifications.dart';
          
    class AppPushNotificationsContainer extends StatelessWidget {
      final Widget child;
      const AppPushNotificationsContainer({
        Key? key,
        required this.child,
      }) : super(key: key);
          
      @override
      Widget build(BuildContext context) {
        String? sessionToken;
        return FirePushNotificationsProvider(
          config: FirePushNotificationsBlocConfig(
            logEvents: true,
            paramBuilder: (event) {
              return event.maybeMap(
                removeToken: (value) {
                  return {
                    "authToken": sessionToken,
                  };
                },
                orElse: () {
                  return {};
                },
              );
            },
          ),
          child: AuthenticationBasicBlocListener(
            onLogout: (context, token) {
              sessionToken = token;
              context.read<FirePushNotificationsBloc>().removeToken();
            },
            child: Builder(
              builder: (context) {
                return PushNotificationListener(
                    onEvent: (context, event) {
                      event.mapOrNull(
                        notificationReceived: (value) {
                          context.read<AppNotificationBloc>().getNotifications();
                          context.read<AppNotificationBloc>().getUnreadCount();
                        },
                      );
                    },
                    child: child);
              },
            ),
          ),
        );
      }
    }
    

  • Use that container to wrap your widget tree at your main widget tree, we recommend wrapping a widget that is behind an authentication guard
