Implementing GestureDetector

Widgets & Design

HI FFs,

I have stacked a Carousal Over a Google map, the issue is that when the user slides/swaps the carousel the map also moves with his gesture... I want to limit Google Map gesture response except when the user intends to use the map.

anyone can show me how to implement this?

What have you tried so far?

I asked ChatGPT and this is its response:

Step-by-Step Solution

  1. Wrap the Carousel in a GestureDetector:

    • Use a GestureDetector to detect swaps on the carousel and prevent them from propagating to the map.

  2. Set Up the GestureDetector:

    • You can handle the onPanUpdate gesture to capture the swaps events.

Example Implementation

  1. Wrap the Carousel with GestureDetector:

    • In your FlutterFlow project, wrap your carousel widget with a GestureDetector.

  2. Disable Map Interaction:

    • When the user swaps on the carousel, disable the map's gestures.

Example Code Snippet

Stack(
  children: [
    GoogleMap(
      // Your Google Map configuration
      gestureRecognizers: Set(), // Prevents gestures from being recognized
    ),
    GestureDetector(
      onPanUpdate: (details) {
        // Handle swaps gestures here
      },
      child: CarouselSlider(
        items: [
          // Your carousel items
        ],
        options: CarouselOptions(
          // Carousel settings
        ),
      ),
    ),
  ],
)

Final Touches

  • Make sure to set the gestureRecognizers to an empty set in the Google Map widget to prevent any gestures from being recognized while swiping the carousel.

  • You can also manage enabling/disabling gestures based on user interactions if you want to allow map gestures at other times.

This approach should effectively prevent the map from moving when swiping the carousel. Let me know if you need further assistance!
