NotificationParams

NotificationParams controls the appearance of two notification types:

Missed call notification — shown when an incoming call times out without being answered. Assigned to CallKitParams.missedCallNotification.
Calling notification — shown persistently while a call is in progress (outgoing or accepted). Assigned to CallKitParams.callingNotification.

import 'package:flutter_callkit_incoming/flutter_callkit_incoming.dart';

const params = CallKitParams(
  id: '44d915e1-5ff4-4bed-bf13-c423048ec97a',
  nameCaller: 'Jane Doe',
  missedCallNotification: NotificationParams(
    showNotification: true,
    isShowCallback: true,
    subtitle: 'Missed call',
    callbackText: 'Call back',
  ),
  callingNotification: NotificationParams(
    showNotification: true,
    isShowCallback: true,
    subtitle: 'Calling...',
    callbackText: 'Hang Up',
  ),
);

Constructor

const NotificationParams({
  int? id,
  bool? showNotification,
  String? subtitle,
  String? callbackText,
  bool? isShowCallback,
  int? count,
})

Fields

showNotification

bool?

default:"true"

Whether to show the notification at all.

For missedCallNotification: controls whether a missed-call notification appears when the incoming call times out.
For callingNotification: controls whether a persistent notification is shown during an active/outgoing call.

isShowCallback

bool?

default:"true"

Whether to display a callback action button inside the notification.

For missedCallNotification: shows a “Call back” action that triggers Event.actionCallCallback when tapped.
For callingNotification: shows a “Hang Up” action to end the call from the notification.

subtitle

String?

Secondary text displayed below the caller name in the notification.Typical values:

Missed call notification: "Missed call"
Calling notification: "Calling..."

callbackText

String?

Label for the callback/action button in the notification.Typical values:

Missed call notification: "Call back"
Calling notification: "Hang Up"

int?

Internal notification ID used by the Android notification manager. If not set, the plugin assigns one automatically. Only relevant when you need to update or cancel the notification programmatically outside of the plugin.

count

int?

Badge count shown on the notification. Used by some Android launchers to display a numeric badge on the app icon.

Usage context

NotificationParams is reused for both notification slots but the semantics of each field differ slightly depending on which slot it occupies:

Field	`missedCallNotification`	`callingNotification`
`subtitle`	”Missed call"	"Calling…”
`callbackText`	”Call back"	"Hang Up”
`isShowCallback`	Shows recall action	Shows hang-up action
`showNotification`	Show on timeout	Show during active call
