Description

Hello Mapbox team.

Since upgrading from mapbox_maps_flutter v1.1.0 to v2.8.0 we have been getting heaps of "Unable to establish connection on channel" errors in production which is taking up our Sentry quota. (As part of this upgrade I also went from flutter v3.22.0 to v3.29.0 so maybe this could have contributed?)

Here are examples of these types of errors we are seeing:

PlatformException(channel-error, Unable to establish connection on channel: "dev.flutter.pigeon.mapbox_maps_flutter._PointAnnotationMessenger.setTextIgnorePlacement.0"., null, null)

PlatformException(channel-error, Unable to establish connection on channel: "dev.flutter.pigeon.mapbox_maps_flutter._PointAnnotationMessenger.setTextOptional.0"., null, null)

PlatformException(channel-error, Unable to establish connection on channel: "dev.flutter.pigeon.mapbox_maps_flutter._PointAnnotationMessenger.setIconIgnorePlacement.0"., null, null)

PlatformException(channel-error, Unable to establish connection on channel: "dev.flutter.pigeon.mapbox_maps_flutter._PointAnnotationMessenger.setSymbolZOrder.0"., null, null)

This is happening on a range of devices and operating systems (both android and ios)

Looks like there is a similar issue that got raised 3 days before this one https://github.com/mapbox/mapbox-maps-flutter/issues/976

Any ideas on what is going wrong?

Research direction

Start by comparing the upgrade from mapbox_maps_flutter v1.1.0 to v2.8.0 and Flutter v3.22.0 to v3.29.0, then review related issue #976. Reproduce the channel errors across Android and iOS and identify why the listed PointAnnotationMessenger calls fail; done means those production errors no longer occur.
