I have a list builder which listens for changes to a riverpod provider state property ‘isScrolling’ and as part of a Listener onPointerDown event I set the ‘isScrolling’ state to true.

The ListView does not automatically start scrolling even though it has detected and rendered the change, I have to take my finger off and start scrolling again, or add a second finger to start the scroll. Is there a way to get the physics to apply whilst the initial finger that started the event stays on the device?

I am new to Flutter so I am open to any solutions to allow the requirement to be met.

final isScrolling = ref.watch(provider.select((s) => s.isScrolling));


Listener(
      onPointerDown: (event) {
        // gesture logic here
        ref.read(provider.notifier).setIsScrolling(true);
      },

      child: ListView.builder(
        itemCount: 3,
        scrollDirection: Axis.vertical,
        physics: isScrolling == true ? const AlwaysScrollableScrollPhysics() : const NeverScrollableScrollPhysics(),
        itemBuilder: (context, index) {
          return Column(
            children: [
             ///
            ],
          );
        },
      ),
    )
},

The requirement is because I have child widgets that listen to ‘isScrolling’ state and disable canvas drawing to allow the user to scroll, pan & zoom.
