Flutter testing fails on the CLI but not in GitHub actions pull request automations

[palisadoes]

Describe the bug

1. The flutter test or flutter test --coverage commands fail on the CLI, but pass in the GitHub action testing.
2. The sections that fail are below. Detailed output can be found later in the description

   00:04 +21 -1: loading /home/peter/GitHub/talawa/test/widget_tests/pre_auth_screens/waiting_page_test.dart [E]        
     Failed to load "/home/peter/GitHub/talawa/test/widget_tests/pre_auth_screens/waiting_page_test.dart": lock failed, path = '/home/peter/Documents/currentuser.lock' (OS Error: Resource temporarily unavailable, errno = 11)
   

   and

The cause of the issue is related to using Hive as you can see in the detailed output below.

To Reproduce
Steps to reproduce the behavior:

1. Run the command flutter test or flutter test --coverage

Expected behavior

1. The command should execute with no errors on the CLI.
2. The testing should continue to pass in the automated GitHub action when PRs are submitted.

Actual behavior
The command executes with the errors noted above. See below for detailed output.

@CyberWake Do you know why this is happening? The tests work in GitHub it seems, but not from the CLI.

[guptapriyanshu7]

Flutter test is accessing some flles concurrently from the system managed by Hive which puts a lock when it is accessed by one test so that other tests cannot touch it. My speculation is that on Github actions there is only one thread on which all tests are running so this problem doesn't occur.
One workaround can be to make different files for Hive.
I would like to work on this.
