autoCancel: Auto cancel Notification

By using this property we can cancel the Notification on click by set value true

How to show the Progress notification

By using the progress property we can achieve this.

In the example i am going to show the notification progress update by every 2 seconds

import 'package:flutter/material.dart';

import 'package:flutter_local_notifications/flutter_local_notifications.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(

primarySwatch: Colors.pink,
),
home: MyHomePage(title: 'Flutter Push Local Notification'),
);
}
}

class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);

final String title;

@override
_MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State {

GlobalKey _scaffoldKey = GlobalKey();
FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
new FlutterLocalNotificationsPlugin();
@override
void initState() {

print("Initialize 1");
initNotifications();
super.initState();
}
@override
Widget build(BuildContext context) {

return Scaffold(
appBar: AppBar(
// Here we take the value from the MyHomePage object that was created by
// the App.build method, and use it to set our appbar title.
title: Text(widget.title),
),
body: Center(
child: RaisedButton(
child: Text("Generate Notification",style: TextStyle(color: Colors.white,fontSize: 20),),
onPressed: _onTap,
color: Colors.pink,
),
),
// This trailing comma makes auto-formatting nicer for build methods.
);

}
_onTap() async {
for(var k=0;k<10;k++)
{
var msg="Downloading...";
if(k==9)
msg="Completed";
await Future.delayed(Duration(seconds: 5),() async {
var androidPlatformChannelSpecifics = AndroidNotificationDetails(
'1', 'rrtutors', 'flutter snippets',
importance: Importance.Max, priority: Priority.High,
showProgress: true,progress: (k+1)*10,autoCancel: false,maxProgress: 100,color: Colors.pink,
icon: 'like'
);
var iOSPlatformChannelSpecifics = IOSNotificationDetails();
var platformChannelSpecifics = NotificationDetails(
androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
await flutterLocalNotificationsPlugin.show(0, 'rrtutors',
msg, platformChannelSpecifics,
payload: 'item x');

});
}

}
void initNotifications() async{

var initializationSettingsAndroid =
new AndroidInitializationSettings('ic_launcher');
var initializationSettingsIOS = new IOSInitializationSettings(
onDidReceiveLocalNotification: (i, string1, string2, string3) {
print("received notifications");
});
var initializationSettings = new InitializationSettings(
initializationSettingsAndroid, initializationSettingsIOS);
flutterLocalNotificationsPlugin.initialize(initializationSettings,
onSelectNotification: (string) {
print("selected notification $string");
});

}

While run the above code the notification will update its progress.

Flutter Notification click events to navigate other screen

How to Navigation other screen while open Notification

flutterLocalNotificationsPlugin.initialize(initializationSettings,
onSelectNotification: (string) {
print("selected notification $string");

Navigator.push(context, MaterialPageRoute(builder: (context){

return Scaffold(
appBar: AppBar(title: Text("Notification Screen"),),

body: Center(
child: Container(
color: Colors.pink,
padding: EdgeInsets.all(8),
child: Text("Navigation from Notifiation ",style: TextStyle(color: Colors.white,fontSize: 20),),
),
)
);
}));
});
