Demonstrates how to use the notification_channel_manager plugin.
A small channel-manager UI that exercises the whole API:
- browse the app's notification channels and groups (with pull-to-refresh),
- create channels with every option the plugin supports — importance, group, badge, lights with a color, vibration (lib/channel_form_page.dart),
- inspect a channel as Android stored it and update the fields Android allows changing (lib/channel_detail_page.dart),
- create/update groups (lib/group_form_page.dart),
- delete individual channels and groups, or everything at once,
- send a test notification to any channel to hear/see its settings in action (lib/test_notifier.dart — posting is out of scope for the plugin, so the example brings its own tiny sender in MainActivity.kt, including the Android 13+ permission request),
- send a test bubble notification (Android 11+): a MessagingStyle
conversation tied to a long-lived shortcut with BubbleMetadata expanding
into BubbleActivity. Note that bubbles only float once the user allows
bubbles for the app (Settings → Notifications → Bubbles, or
adb shell cmd notification set_bubbles <package> 1); otherwise the notification shows with a bubble affordance instead.
Run it on an Android device or emulator with flutter run.
The plugin's integration tests also live here; run them with a device attached:
