I have the same problem, can someone suggest a solution?

Wonder if this is related to mouse zoom issue as well with iOS #1414

[ibrierley]

and #1354

[FeofanGreek]

Don't work zoom with fingers multi_finger_gesture.dart

Hey @FeofanGreek, if you're still interested, can you try this out with the latest 'master' and Flutter 3.10?

[JosefWN]

I think we might need some more context if this issue persists on v5.0.0, last I tried on v4.0.0 on iOS it worked.

Do you see the issue both in the emulator and in the deployed app?

[ibrierley]

I was wondering if this was related to #1543 ?

[JosefWN]

It could be, especially if only the emulator is impacted since the touch behavior on MacOS is a bit different from iOS. I don't run the emulator, I only test on actual devices, where I haven't seen this issue personally. Better test on v5.0.0 before digging deeper at least.

[JaffaKetchup]

Very similar to #1634.

Rarely: Occurs every so often

Might not be entirely related, but on MacOS I have a similar issue occurring somewhat rarely, regardless of which app I am using (including Mac apps shipped with the OS, like Preview). I think that's a touchpad driver issue.

It would be very interesting if anyone with the problem could run the latest tagged version of flutter_map on an actual device, to try to provoke it and capture any errors/warnings in the logs. It hasn't happened to me personally yet, so there might be some slight difference in how we've set things up, so a MWE to reproduce would be nice too.

@JosefWN may I ask you to check if your descibed MacOS bug gets fixed in #1733 and test the PR for apple devices in general? Most of the gesture bugs are currently on MacOS or iOS but I'm not able to test them because of the lack of (nearly up to date) apple devices.
