codifyiq_notification_center

A Play Store-style notification center for tracking long-running, user-initiated tasks (uploads, downloads, multi-step background work) without blocking the UI.

Widgets

• NotificationBellButton — an AppBar action with a stoplight-coded Material 3 badge. Opens an anchored dropdown on wide viewports and a full-screen NotificationCenterPage on narrow ones.
• NotificationCenterController — a ChangeNotifier exposing start / updateProgress / complete / fail / dismiss / clearCompleted / clearAll / markAllSeen. The widget is UI-only; you drive it from your own task layer.
• NotificationCenterPanel / NotificationCenterPage — list view with In progress, Failed, and Completed sections.
• NotificationCenterScope — an InheritedNotifier for ambient controller lookup.

Installation

dependencies:
  codifyiq_notification_center: ^1.0.0

Usage

import 'package:codifyiq_notification_center/codifyiq_notification_center.dart';

final controller = NotificationCenterController();

controller.start(id: 'job-1', title: 'Uploading invoice.pdf', progress: 0);
controller.updateProgress('job-1', progress: 0.42);
controller.complete(
  'job-1',
  description: 'Saved to Documents/invoice.pdf',
  action: NotificationItemAction(label: 'Open', onPressed: openFile),
);

AppBar(actions: [NotificationBellButton(controller: controller)]);

The bell is a stoplight, not a count: error → running → success → none, with the icon swapping to a filled variant whenever items are tracked (state conveyed by shape as well as color, per WCAG 1.4.1).
