I don't need a server or anything, but basically I want to do a scheduled notification locally.
I tried using react-native-push-notification but it says I need firebase?
I just want to schedule a notification when the app is opened for a certain time
If you want to use only local notification with react-native-push-notification and avoid using firebase, refer to this part of readme:screenshot of readme
Don't worry about IOS, this library won't be used there

I'm new to react native and I need some help.
I need to implement a feature that the application informs the client if it has an appointment on the day and if it does, notify him, if not, not notify.
However, I believe that the application needs to check in the API if it has any scheduling and if it has to check if it is on the scheduling day and if it is, send a notification to the client
Correct me if I'm wrong
I'm using react-native-push-notification
But I can't make the logic for this to happen, I can offer my code so they can help me
Suggestion:
You can opt to go with the react-native-push-notification with firebase so that You can able to send the push notification whenever you want through the blackened.
Firebase documentation:Cloud Messaging
I am using OneSignal in my Flutter application to receive notifications. I have created my own table within Flutter to save notifications but I cannot save messages that have been sent whilst the app has been terminated. However, I have found that the OneSignal package has it's own database installed on the device which captures everything no matter what state the application is in! So, to avoid duplicating data I want to use this database instead. It is located outside of the flutter app folder which is my issue (see image below).
How do I access this database? Does anybody know if it is the same on iOS (I haven't been able to check at this time).
Many thanks.
It's important to understand that if an app has been terminated, any onReceived handler will not be fired. We don't recommend using the local db at all. Your best bet is to use the respective notification extender services for each platform. Though you will have to write native code for this! Cheers
Edit:
ANDROID - NotificationExtenderService - This can be setup to receive silent notifications when your app is not running or to override how notifications are shown in the notification shade. See the Background Data and Notification Overriding section to set this up.
I have developed a simple android app using Firebase database to store stuff.
Now, I want to set up notifications for each time a button is clicked.
Each time the button is clicked, it will take some info from firebase (text mostly) and will send a notification to anyone who downloaded the app.
I understood that simply creating a notificationManager won't work as needed.
I also heard about Firebase Cloud Messaging but im pretty new to this so I must know what I should start learning to make that work out.
So, if you have any good tutorials or anything helpful, that would be great!
Thanks!
You need to receive for the FCM in android app. Refer this doc. And you need to can use database triggers in firebase cloud functions to send FCM notification, or you need to deploy a cloud http function to do so.
Is it possible to send permanent notification from firebase cloud functions? User can't dismiss that notification?
For iOS you cannot, but Android you could setup a local notification using remote config.
iOS Remote Notifications
While you could send the same notification over and over again, control of the notifications is at the OS level of the client device. iOS would never let you create a local or remote notification that cannot be dismissed because it would be a poor user experience. In addition, I think you would find that your users would not be happy about it as well.
An alternative, would be to create a custom UI Header in your app that includes a label. You could then use Firebase Remote Config to set a value for that label, that way you can deliver the same message to all users of your app.
Android Push Notifications
In Android, it looks like you can have permanent notifications. However, it looks like this is controlled at the client level. So I still recommend the remote config option here as well. Set the value of the remote config, and then generate a local notification and set the notification to not clear.
notification.flags |= Notification.FLAG_NO_CLEAR;
Perhaps, a key/value pair could be sent from your Firebase Cloud Message call, but you will run into other issues as well. When should the function be called? Will you generate a new notification for every new user added to Firebase? This could become more expensive versus the remote config route.
Google Chrome Notifications
The remote config option should scale to this as well. A quick Google search didn't show anything that would suggest you can do a permanent notification like Android. And even if you could then your solution wouldn't work in Safari and other browsers.
I want to notify updates from server to a set of android applications. I want to know whether it is possible with Firebase push notification service without manually registering the apps. If it is not, please help me with any other solution.
