Error while stopping the front-end service

[TT-xiaoseven]

I am using the v8.17.0 version of the plugin to implement the background positioning and activation function, but when I stopped the background service, two problems occurred:

Problem 1: Another IM plugin reported the following error

E/flutter (21410): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: MissingPluginException(No implementation found for method markC2CMessageAsRead on channel tencent_cloud_chat_sdk)

I resolved the issue by modifying the source code in ForegroundTask. kt of this plugin and logging out the FlutterEngine. destroy() method.

Problem 2: The other localization plugin flutter-bmflocation is unable to receive localization callbacks.

This positioning callback is valid after the front-end service is initially enabled. Once the front-end service is turned off, it is no longer available, and even if the positioning plugin is reinitiated, it cannot receive callbacks again.

Now, I am troubled by the second question and hope to get a solution as soon as possible.
