Description

When using 3 or more fingers on the Google Map, then the app throws an exception.
After this exception is thrown once, it also gets thrown when using any other gesture (one or two fingers).
The problem then persists until the app is restarted.

Test Environment

I tested this on a Xiaomi Mi9T Pro with the Xiaomi.eu rom version 20.10.29 using my main app, a custom made app for this testing purpose and it even affects the example app itself.
Edit 1: Also tested now on COL-L29 (Honor 10) with Android 9, EMUI 9.1.0
Edit 2: Also tested by @takinok on Galaxy S20 5G with Android 10 (see AndreHaueisen/flushbar#161)
Edit 3: Also tested by @rakeshlanjewar on Redmi Note 6 Pro (tulip)

Version used

According to my own pubspec.lock, I am using google_maps_flutter 1.0.6 (still exists in 2.0.2) and location 3.0.2 (still exists in 4.1.1).
Edit 1: Also, this affects the example app, which only has google_maps_flutter.
Edit 2: It doesn't only affect google_maps_flutter, but also various other libraries and widgets

Fix

A workaround can be found in the PRs #72611, #82013, and #78874 (especially notice the different approaches mentioned in #78874 (comment)).

A real fix would need the engine to be modified. Right now, when a 3-fingers (or more) gestures is registered on the device, the engine registers the gesture as some pointer down events, one for every finger. After that a position update, then a cancel pointers, and another position update event follow. Since the downTimeMillis get reset and the pointerPositions and pointerProperties lists have inconsistent lengths, the toAndroidMotionEvent function fails when either unpacking the downTimeMillis or when mapping the pointerPositions or pointerProperties lists to their corresponding pointers (since pointerPositions.length > pointerProperties.length).

flutter doctor -v

It should be worth noting, that I am also affected by #11940 and have not applied any workaround or whatsoever (the flutter and dart plugins are installed of course in Android Studio)

Can you provide flutter doctor -v ? Also location is a 3rd party plugin. Can you remove location plugin code and try again to see if you still get exception ?
Thanks.

Without location:

As I already said, this issue also affects the example app at this specific commit (the newest one) as well, which doesn't have the location plugin installed.

Tested with official google_maps_flutter plugin using Android 8.1.0 device on latest stable and used 3 and 4 fingers simultaneously to drag the map, but didn't see the issue. The map scrolled and moved properly.

Can you check if this is only happening on specific device you have or on other emulators too ?
Thanks.

Also tested on COL-L29 (Honor 10) with Android 9, EMUI 9.1.0.
Same exception: https://pastebin.com/pbKz4ZJG

How can I simulate a three-finger gesture in the emulator or is that even possible?

That was my bad to suggest to try on emulator, didn't realize that :-)
Anyways, I also tried on Samsung S10+ device but didn't see the issue nor the exception in the log.

Since I don't have the devices you mentioned, I am not sure if it's happening only on the said specific devices.
Can you provide video of the issue ?

No problem, okay :)

Interesting, maybe it is related to my devices using a custom Android flavor (Honor 10 uses EMUI, Mi 9T Pro uses MIUI).
I uploaded a video of the issue here: https://www.youtube.com/watch?v=38tWaMTFqEQ
I hope, that this is sufficient. If not, I can record more parts of the issue or something separately again.

I am unable to replicate the issue using gestures (multiple fingers at once to scroll), but per author and video, it seem to be happening consistently. Keeping this issue open for further analysis.

You can apply the patch in the mentioned PR to your local Flutter installation.
Otherwise you have to wait for an official patch to be released. I am working on a new PR with an appropriate test such that it can get merged asap

As seen in the PR, the engine needs to get fixed. However, I don't have enough knowledge with that. So, any help is welcome from now on!

Reproducible for both Virtual Display and Hybrid-Composition implementation: https://github.com/Sunbreak/hybrid_composition.trial

Comfirmed that https://github.com/flutter/flutter/pull/72611/files fixes the problem on hybrid_composition

This fixed my issues where the app freezes after detected 3 fingers gestures

@onebuck-code This isn't a fix. It's only a workaround as explained already. This issue has to get fixed in its core, which lies inside the engine.
