Old behavior

When we are checking for Permission status it was working previously and we have pushed many applications using the same . we start facing the issue after updating the permission_handler: ^12.0.1 latest

Current behavior

I/flutter ( 4361): [IMPORTANT:flutter/shell/platform/android/android_context_vk_impeller.cc(62)] Using the Impeller rendering backend (Vulkan).
I/flutter ( 4361): MissingPluginException(No implementation found for method checkPermissionStatus on channel flutter.baseflow.com/permissions/methods) ::-R #0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:365)
I/flutter ( 4361):
I/flutter ( 4361): #1 MethodChannelPermissionHandler.checkPermissionStatus (package:permission_handler_platform_interface/src/method_channel/method_channel_permission_handler.dart:17)
I/flutter ( 4361):
I/flutter ( 4361): #2 checkVideoPermission (package:test_project/video_upload/video_upload_demo_page.dart:41)
I/flutter ( 4361):
I/flutter ( 4361): #3 VideoUploadManager.pickVideo (package:test_project/video_upload/video_upload_demo_page.dart:295)
I/flutter ( 4361):

Steps to reproduce

Permission permission;
permission = Permission.videos;
/// STEP 1 -> CHECK CURRENT STATUS
PermissionStatus status = await permission.status;

then we are able to see the log i have shared below:
