[BUG] Test cases fails due to MissingPluginException for setAppGroupId

[tanmoy-tide]

Problem to solve

All the test cases of a class fails where the setAppGroupId function is called for home_widget.

MissingPluginException(No implementation found for method setAppGroupId on channel home_widget)
This test failed after it had already completed.
  Make sure to use a matching library which informs the test runner
  of pending async work.
  package:flutter/src/services/platform_channel.dart 332:7   

Proposal

Adding injectable class so that mock object can be injected to the class where HomeWidget is used
