This feature allows users to store data locally on their device using SQLite and upload it to a remote database when required. The data is stored offline in SQLite, ensuring accessibility even without an internet connection. To upload the stored data, the user can simply click on the "Upload" option available in the Settings menu. This action requires an active internet connection. Once triggered, the app retrieves the locally stored data from SQLite and sends it to the remote server. If the upload is successful, the user receives confirmation, and the data can be marked as synced to prevent duplicates. If the internet connection is unavailable, the user is notified to try again later. This ensures a smooth experience for managing and uploading data while providing offline functionality.
