Link to Config Item from configuration synchronize page

This would be a great feature to have. Especially with projects that are under active development / enhancements / customization, there would be a lot of time savings for its developers.

I have created a patch that adds the following link to the 'View Differences' drop-down button on the /admin/config/development/configuration page:

• "'Export this config' with a target URL of /admin/config/development/configuration/single/export/{{type}}/{{name}}

I have omitted the 'Import this config' link because there is no option for single config selection on the import page.

Kind of change will require test coverage.

Probably also submaintainer sign off.

I have added test coverage for the changes. The merge request is ready for review now.

Prashant.c → made their first commit to this issue’s fork.

Test failure.

Corrected the issue where the configuration type entity did not exist.

Applied MR !5953 on D11.x.

The Export this config button is working fine which is redirecting to export config page with parameters os selected config entity.

However the Import to this config link is not implemented.

1. Introducing a new link labeled "Import this configuration."
2. Clicking on the link will redirect the user to "/admin/config/development/configuration/single/import/[config_type]/[config_name]."
3. The "Paste your configuration here" textarea will be automatically populated with the original configurations.
4. Press the "Import" button to initiate the import of the default configurations.

However, there are still pending tasks, including code review, code cleanup, and testing.

1. Fixed phpcs issue regarding unused use statement.
2. For removed configs, single "Import this config" link leads to 'false' text in the import text area because the config doesn't exist. Added config exists check on the singe import page.
3. Added test coverage for 'Import this config' link.

MR seems to have failures. There are some backwards compatibility concerns as that path will now be broken. May need to cover that.

Refactored the code and removed 'Import this config' link for configs under Removed section.

Hi @riyas_nr

Did a code review and included few more suggestions.

1. Added below parameters as optional.
1. $sync_storage in constructor of \Drupal\config\Form\ConfigSingleImportForm
2. $entity_type_manager in constructor of \Drupal\config\Form\ConfigSync
2. Updated deprecation warning for both parameters.
3. Added change records for above parameters.

Left more comments.

1. Added typehints for method parameters and properties
2. Changed method name updateImport to getStagedConfigByName()
3. Changed access modifier of helper functions to protected
4. Moved optional parameters to end of the constructor arguments

@alexpott are we good to remove subsystem review?

Tried testing this one out.

On the configuration sync page I am seeing the dropdown for export/import

Export seems to work correctly

But import whenI click it I get redirected to the import form. Dropdown is empty and text area is also empty. Seems odd that the dropdown for config was empty at least.
