Building Completed Task Page | To Do App | FlutterFlow for Beginners

Step-by-Step Tutorial: Building a Completed Task Page in a To-Do App using FlutterFlow

1. Duplicate the Completed Page:

   • Start with a completed page that shows different items/tasks.
   • Right-click on the completed page and duplicate it.

2. Update Text to Completed:

   • Change the text on the duplicated page to "Completed".

3. Filter Completed Tasks:

   • Edit the list view to show tasks where the completed field is equal to false.
   • Change the filter to true to show only completed tasks.

4. Add Logic to Checkbox:

   • Double-click into the component containing the checkbox.
   • Go to the checkbox and add logic by going to the action flow editor.

5. Define, Bind, and Pass Action Parameter:

   • Click on the canvas to access parameters.
   • Add a parameter of type action called "check action".
   • Bind the action to the toggle on action.
   • Pass the action by going to the component properties and selecting the action (updating a document).

6. Update Document Reference:

   • Open the document reference with a backend query.
   • Set the completed property to true for completed tasks.

7. Display Completed Tasks:

   • Set the initial page to the completed tasks page.
   • Reload the page to view completed tasks.

8. Disable Checkbox and Enable Navigation:

   • Disable the checkbox by setting a variable in the disabled options.
   • Remove the navigate action from the completed page to prevent unintended navigation.

9. Manage Nested Tap Actions:

   • Flutter efficiently manages nested tap actions using hit testing and gesture disambiguation.
   • Ensure the most specific widget responds to the event.

10. Implement Unchecking Completed Tasks:

• Create a parameter to handle toggling off the completed status when the checkbox is unchecked.
• Update the database by referencing the document and setting the completed field to false.

11. Test and Verify:

• Turn off the disabling component on the checkbox.
• Test the functionality by checking and unchecking tasks to ensure they are completed or reverted.

12. Finalize and Review:

• Confirm that completing a task updates the backend and displays it on the completed tasks page.
• Ensure navigation and checkbox behavior align with the desired app functionality.

By following these steps, you can successfully build a completed task page in your To-Do app using FlutterFlow.
