flutter_notification_channel
Androidで通知チャンネルを設定するためのプラグイン
firebase_messaging のバージョン 7.0.3(現在のバージョン)およびそれ以下のバージョンでは、通知チャンネルの設定が許可されていないため、通知は音を鳴らさず、ロック画面に表示されず、バブル表示されないなどになります。このプラグインは、Androidで異なる設定を持つ通知チャンネルを作成する目的だけです。その後、firebase_messaging と一緒に使用できます。

This plugin is made to register notification channels with custom configurations on Android. For more details read this https://developer.android.com/training/notify-user/channels Why is it necessary? E.g. firebase_messaging version 7.0.3 (current) and lower do not allow to set up a notification channel, thus notifications don't play any sounds or do not display on locked screen, or don't bubble and so on. This plugin is made merely for the purpose of creation a notification channel with custom configurations on Android. The channels then can be used along with firebase_messaging.
Simply call it like this
var result = await FlutterNotificationChannel().registerNotificationChannel(
description: 'Your channel description',
id: 'your_channel_id',
importance: NotificationImportance.IMPORTANCE_HIGH,
name: 'Your channel name',
visibility: NotificationVisibility.VISIBILITY_PUBLIC,
allowBubbles: true,
enableVibration: true,
enableSound: true,
showBadge: true,
);
print(result);
The plugin supports the following notification importance levels:
NotificationImportance.IMPORTANCE_MIN (1): Minimal importance, might not be shownNotificationImportance.IMPORTANCE_LOW (2): Low importance, shows in shade and potentially status bar but not audibly intrusiveNotificationImportance.IMPORTANCE_DEFAULT (3): Default importance, shows everywhere and makes noise but doesn't visually intrudeNotificationImportance.IMPORTANCE_HIGH (4): Higher importance, shows everywhere, makes noise and peeks, may use full screen intentsNotificationImportance.IMPORTANCE_MAX (5): Maximum importance, most intrusive level, should be used sparingly for critical notifications onlyFor critical notifications that require immediate user attention:
var result = await FlutterNotificationChannel().registerNotificationChannel(
description: 'Critical system alerts',
id: 'critical_channel_id',
importance: NotificationImportance.IMPORTANCE_MAX,
name: 'Critical Alerts',
visibility: NotificationVisibility.VISIBILITY_PUBLIC,
allowBubbles: true,
enableVibration: true,
enableSound: true,
showBadge: true,
);
Then, when you send a message to firebase like this, specify your android_channel_id and sound: "default" in order to play a default sound if you set "enableSound" in plugin. If you don't do this, the sound wont play at all on android 9 (I have no idea why)
