[BUG] Swiping through gallery doesn't work sometimes

[ashilkn]

Describe the bug When using photo_view to swipe through photos in a gallery, swiping (horizontal drag gesture) doesn't work sometimes. I enabled debugPrintGestureArenaDiagnostics and the logs gives an idea of what's happening internally.

When swiping works:

I/flutter (26426): Gesture arena 170  ❙ ★ Opening new gesture arena.
I/flutter (26426): Gesture arena 170  ❙ Adding: DoubleTapGestureRecognizer#b7996(debugOwner: PhotoViewGestureDetector)
I/flutter (26426): Gesture arena 170  ❙ Adding: PhotoViewGestureRecognizer#36e70(debugOwner: PhotoViewGestureDetector)
I/flutter (26426): Gesture arena 170  ❙ Adding: HorizontalDragGestureRecognizer#3afc9(start behavior: start)
I/flutter (26426): Gesture arena 170  ❙ Closing with 3 members.
I/flutter (26426): Gesture arena 170  ❙ Accepting: HorizontalDragGestureRecognizer#3afc9(start behavior: start)
I/flutter (26426): Gesture arena 170  ❙ Self-declared winner: HorizontalDragGestureRecognizer#3afc9(start behavior: start)

When swiping doesn't work:

I/flutter (26426): Gesture arena 169  ❙ ★ Opening new gesture arena.
I/flutter (26426): Gesture arena 169  ❙ Adding: DoubleTapGestureRecognizer#b7996(debugOwner: PhotoViewGestureDetector)
I/flutter (26426): Gesture arena 169  ❙ Adding: PhotoViewGestureRecognizer#36e70(debugOwner: PhotoViewGestureDetector)
I/flutter (26426): Gesture arena 169  ❙ Adding: HorizontalDragGestureRecognizer#3afc9(start behavior: start)
I/flutter (26426): Gesture arena 169  ❙ Closing with 3 members.
I/flutter (26426): Gesture arena 169  ❙ Accepting: PhotoViewGestureRecognizer#36e70(debugOwner: PhotoViewGestureDetector)
I/flutter (26426): Gesture arena 169  ❙ Self-declared winner: PhotoViewGestureRecognizer#36e70(debugOwner: PhotoViewGestureDetector)

So at times PhotoViewGestureRecognizer wins instead of HorizontalDragGestureRecognizer which is causing this issue.

To Reproduce Use the example app (https://github.com/bluefireteam/photo_view/releases/tag/0.14.0) and go to "gallery". Open the first photo from the gallery and swipe to the next photo. The first swipe doesn't work, the second does. The bug comes up randomly too while swiping through photos.

What is the current behaviour? Swiping (horizontal drag gesture) doesn't work sometimes.

Expected behaviour Swiping will always work and shows next/prev photo.

Which versions of Flutter/Photo View, and which browser / OS are affected by this issue? Did this work in previous versions of Photo View? Flutter v3.10.6 photo_view v0.14.0 Reproducible on both Android and iOS.

Same issue. Every first swipe it doesn't work:

I/flutter (26851): Gesture arena 581 ❙ ★ Opening new gesture arena. I/flutter (26851): Gesture arena 581 ❙ Adding: DoubleTapGestureRecognizer#2dfb4(debugOwner: PhotoViewGestureDetector) I/flutter (26851): Gesture arena 581 ❙ Adding: PhotoViewGestureRecognizer#7fa14(debugOwner: PhotoViewGestureDetector) I/flutter (26851): Gesture arena 581 ❙ Adding: HorizontalDragGestureRecognizer#d9dac(start behavior: start) I/flutter (26851): Gesture arena 581 ❙ Closing with 3 members.

Then on the second on it works: I/flutter (26851): Gesture arena 582 ❙ ★ Opening new gesture arena.

Is there a workaround ?

same issue

I think it's related to "android gesture navigation" because when this is disabled it works without issue.
