Step 1: Set Up an Adalo Account

• Go to the Adalo website and create an account or log in if you already have one.
• Start a new project to build your app or open an existing project where you want to add notifications.

Step 2: Create a Collection for Notifications

• In the Adalo editor, navigate to the "Database" section on the left sidebar.
• Click "+ Add Collection" and name it "Notifications".
• Add properties to the Notifications collection such as "Title", "Message", "User", "Read" (boolean), and "Timestamp".

Step 3: Set Up User Collection

• Ensure you have a "Users" collection in your database. If not, create one.
• Add necessary properties like "Name", "Email", and "Device ID" (for push notifications). The Device ID will be used to target notifications specifically to each user.

Step 4: Define Notification Triggers

• Determine the events in your app that will trigger notifications (e.g., a new message, a comment on a post, a like, etc.).
• Go to the screen where these events occur and add actions to create notification records in the "Notifications" collection.
• For example, in a messaging app, when a new message is sent, add an action to create a new notification entry with relevant details.

Step 5: Display Notifications in the App

• Design a "Notifications" screen or component in your app where users can view their notifications.
• Add a list component to this screen and connect it to the "Notifications" collection.
• Filter the list to show only notifications related to the logged-in user and sort them by "Timestamp" for recent ones first.
• Add visual elements (e.g., icons, badge) to indicate unread notifications by checking the "Read" status.

Step 6: Mark Notifications as Read

• Configure the behavior when a user views a notification (e.g., click or tap on it).
• Add an action to update the "Read" status to true, so the notification is marked as read.

Step 7: Enable Push Notifications (Optional)

• Go to Adalo's marketplace and install a push notification component (e.g., OneSignal or Firebase Cloud Messaging).
• Set up the push notification provider by creating an account on the chosen service (OneSignal or Firebase).
• Obtain the necessary keys and IDs, configure them in the Adalo push notification component settings.
• Add actions to send a push notification alongside creating a notification record when the defined event triggers.

Step 8: Test Your Notification System

• Publish or preview your app and perform actions that are supposed to trigger notifications.
• Verify that notification entries are created in the database.
• Check the notifications screen to ensure they appear correctly for the logged-in user.
• If using push notifications, ensure they are received on the user's device.

Step 9: Debug and Optimize

• Fix any issues observed during testing (e.g., missing notifications, incorrect user targeting).
• Ensure database queries and actions are optimized for performance.
• Regularly review the notification system for improvements and user feedback.
