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.

4 years ago 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.
flutter doctor -v:It should be worth noting, that I am also affected by https://github.com/flutter/flutter/issues/11940 and have not applied any workaround or whatsoever (the flutter and dart plugins are installed of course in Android Studio)

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.

4 years ago 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?

4 years ago @ThexXTURBOXx 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 ?
ThexXTURBOXx
commented
4 years ago 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.

4 years ago 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.

3 years ago Hey can wrap map in listview list just like i did in above comment, Try it because i have also faced same issue but after wrapping GoogleMap in listview solved the problem for me. Please check it once.
ThexXTURBOXx
commented
3 years ago That is indeed very interesting... When wrapping GoogleMap with the correct gestureRecognizers in a ListView with correct itemExtent, the issue seems to be solved. In my opinion however, this seems like a dirty workaround, which should be investigated further. However, thank you for the time being! :)

Yes, it is bit hacky, flutter team needs to look on this.

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 https://github.com/AndreHaueisen/flushbar/issues/161) Edit 3: Also tested by @rakeshlanjewar on Redmi Note 6 Pro (tulip)
Version used
According to my own
pubspec.lock, I am usinggoogle_maps_flutter 1.0.6(still exists in2.0.2) andlocation 3.0.2(still exists in4.1.1). Edit 1: Also, this affects the example app, which only hasgoogle_maps_flutter. Edit 2: It doesn't only affectgoogle_maps_flutter, but also various other libraries and widgetsVideo

A workaround can be found in the PRs #72611, #82013, and #78874 (especially notice the different approaches mentioned in https://github.com/flutter/flutter/pull/78874#issuecomment-811111562).
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
downTimeMillisget reset and thepointerPositionsandpointerPropertieslists have inconsistent lengths, thetoAndroidMotionEventfunction fails when either unpacking thedownTimeMillisor when mapping thepointerPositionsorpointerPropertieslists to their corresponding pointers (sincepointerPositions.length>pointerProperties.length).flutter doctor -vIt 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)
