There could be several reasons why the Listener is failing to identify the drag action from one ListView to another in Flutter, such as:

  1. Incorrect Implementation: The drag and drop functionality requires accurate implementation of the drag API, and incorrect implementation can lead to errors in the detection of drag actions.

  2. Overlapping Gesture Detectors: If there are multiple Gesture Detectors on the page or widgets that are overlapping, the Listener may not be able to recognize the drag action properly.

  3. Incorrect Widget Hierarchy: The widget hierarchy may not have been set up correctly, which can lead to issues with detecting drag actions.

  4. Performance Issues: If the app has performance issues, it may not be able to keep up with the drag and drop actions, leading to errors in recognition.

To address these issues, developers can review their implementation of the drag API, ensure there are no overlapping Gesture Detectors, correct the widget hierarchy, and optimize the code for better performance.
