Allow to set a list of preferred countries

During the editing of the shipping method got the error

TypeError: array_combine(): Argument #1 ($keys) must be of type array, null given in array_combine() (line 90 of modules/contrib/address/src/Element/Country.php).

Had no time to investigate it. Here is a quick fix for the error.

Fabulous, thanks for moving this forward!

Unfortunately, I still can't commit this without tests (as tagged), which the latest patch does not contain.

Also, the summary has some remaining tasks

With patch in #46, I use the field in a render array I get error:

Simple form code:

/**
   * {@inheritdoc}
   */
  public function buildForm(array $form, FormStateInterface $form_state) {


    $form['address'] = [
      '#type' => 'address',
      '#title' => $this->t('Address'),
    ];

    $form['actions'] = [
      '#type' => 'actions',
    ];
    $form['actions']['submit'] = [
      '#type' => 'submit',
      '#value' => $this->t('Send'),
    ];

    return $form;
  }

The error:

Warning: Undefined array key "#preferred_countries" in Drupal\address\Element\Address::processAddress() (line 192 of modules/contrib/address/src/Element/Address.php).

Drupal\address\Element\Address::processAddress(Array, Object, Array)

Added 2 test cases for this: one for views exposed filter setting and the other for widget configuration and make sure selected countries are displayed as only options directly in select and not optgroup.
Also fixed code standards, added missing default values for Address and Country element info and fixed schema for views filter.

Thank you for the improvements, sickness29!

Since this is a major new feature and change in behavior, let's keep it limited to the 2.0.x branch. I'd like to keep the legacy 8.x-1.x branch as stress-free as possible.

Agreed, this can be 2.0.x material at this point, since it's a potentially more "disruptive" new feature.

That said, I'm really excited about this, and will try to make time to review + test soon. Probably within the first week or two of December...

Thanks!

Reworked #49 to apply to 2.0.x

Hi,

I've tested the preferred_countries-2626982-52.patch patch with the current 2.0.x branch and found that the patch doesn't apply due to code expected from the 8.x-1.x branch.

After applying the rejected hunks manually and resolving duplications in AddressDefaultWidget.php (defaultSettings, settingsForm and settingsSummary methods), I've successfully tested the module with preferred countries field.

The attached patch includes these modifications and works as expected. Please find my re-rolled patch attached for review.

Reworked #52 to apply to 2.0.x.

Hello,

Thanks, this applies and runs well against the latest dev. Would be nice to get this committed after all these years.
