TimeTextEditingController class
Custom TextEditingController that handles cursor positioning during text transitions
This controller provides atomic text and cursor updates, ensuring that when text changes occur (especially during formatting transitions), the cursor is positioned correctly without flickering or jumping to unexpected positions.
Key features:
- Atomic text/cursor updates via setTextWithCursor
- Automatic cursor position clamping to valid ranges
- Prevents cursor position loss during text transformations
