Google Tasks Sync

As a user of both the ByDesign and Google Tasks, I want to enable a two-way synchronization between them, so that my tasks and their statuses are consistently updated across both platforms, providing me with a single source of truth for my to-do list.

Acceptance Criteria:

• Given I have an active sync with Google Tasks, when I create a task in ByDesign, then a corresponding task is created in Google Tasks.

• Given I have an active sync with Google Tasks, when I create a task in Google Tasks, then a corresponding task is created in ByDesign.

• Given a task is synced, when I edit its details (e.g., title, due date) in one application, then the changes are reflected in the other.

• Given a task is synced, when I mark it as complete in one application, then it is marked as complete in the other.

• Given I create a sub-task under a synced parent task in ByDesign, then a corresponding sub-task is created under the parent task in Google Tasks.

• Given I create a sub-task under a synced parent task in Google Tasks, then a corresponding sub-task is created under the parent task in ByDesign.

• Given a synced task or sub-task is deleted in one application, then it is also deleted in the other.
