Answer 1

You can achieve this in Android but Its not possible in iOS for now, For android its Full-screen intent notifications and for iOS most you can do is set an custom ringtone when notification is received, You can use the below mentioned library for most of your notification needs:-pub.dev/packages/flutter_local_notifications

Answer 2

yes, obviously it's possible
u can do like this
demo video link : click here for watch video
Future<void> _showNotification() async {
const AndroidNotificationDetails androidPlatformChannelSpecifics =
AndroidNotificationDetails(
'your channel id',
'your channel name',
channelDescription: 'your channel description',
importance: Importance.max,
priority: Priority.high,
