Flutter 本地通知正文未顯示所有通知文本（flutter_local_notifications 包）

Question

我在我的 Flutter 應用程序中使用flutter_local_notifications: ^0.7.1+3來推送日程通知。 這一切都很好，但我的通知正文中的問題是它只顯示一行文本，我無法擴展或拉伸通知以顯示所有通知正文文本。

這是我的嘗試：

class NotificationUtil {
  final notifications = FlutterLocalNotificationsPlugin();
  final int checkOutNotifyId = 0;

  NotificationUtil(BuildContext context) {
    final settingsAndroid = AndroidInitializationSettings('ic_notify_icon');
    final settingsIOS = IOSInitializationSettings(
        onDidReceiveLocalNotification: (id, title, body, payload) =>
            onSelectNotification(context));
    notifications.initialize(
        InitializationSettings(settingsAndroid, settingsIOS),
        onSelectNotification: (context) async => onSelectNotification);
  }

  Future<void> showCheckOutNotify([int maximumCheckoutHours]) async {
    await notifications.periodicallyShow(
        checkOutNotifyId,
        AttendanceConstants.SCHEDULE_NOTIFICATION_TITLE,
        AttendanceConstants.SCHEDULE_NOTIFICATION_BODY +
            '$maximumCheckoutHours Hour/s of your attendance',
        RepeatInterval.Hourly,
        _ongoing);
  }

  NotificationDetails get _ongoing {
    final androidChannelSpecifics = AndroidNotificationDetails(
      'your channel id',
      'your channel name',
      'your channel description',
      importance: Importance.Max,
      priority: Priority.High,
      ongoing: true,
    );
    final iOSChannelSpecifics = IOSNotificationDetails();
    return NotificationDetails(androidChannelSpecifics, iOSChannelSpecifics);
  }

Answer 1

在 [ AndroidNotificationDetails() ] 中添加 [ BigTextStyleInformation('') ]

NotificationDetails get _ongoing {
    final androidChannelSpecifics = AndroidNotificationDetails(
      'your channel id',
      'your channel name',
      'your channel description',
      importance: Importance.Max,
      priority: Priority.High,
      ongoing: true,

      styleInformation: BigTextStyleInformation(''),
    );

Answer 2

如果有人在這里接收 package awesome_notifications，請使用：

notificationLayout: NotificationLayout.BigText,

內部通知內容。
