How to add "Use Default Value" checkbox for custom form field

Question

I have created a form by exending Magento\Backend\Block\Widget\Form\Generic class in my class.

I am adding a field using $fieldset->addField() to my form for which I need to add "Use Default Value" checkbox field like below screenshot.

enter image description here

With dataProvider class in ui_component form, this is done by setting

'arguments' => [
 'data' => [
 'config' => [
 'dataType' => 'text',
 'formElement' => 'input',
 'componentType' => 'field',
 'label' => 'Field',
 'validation' => [
 'validate-digits' => true,
 ],
 /* 
 * Below line of code adds the checkbox which
 * Enable/Disable input field when checked 
 */
 'service' => [
 'template' => 'ui/form/element/helper/service',
 ],
 ],
 ],
]

Any idea on how to set it for my addField function? I have tried it adding as a config parameter but its not working.

$fieldset->addField(
 'field',
 'text',
 [
 'name' => 'field',
 'label' => __('Field'),
 'title' => __('Field'),
 'required' => true,
 'service' => [
 'template' => 'ui/form/element/helper/service',
 ]
 ]
);

Answer 1

Try

$fieldset->addField(
 'field',
 'checkboxes',
 [
 'name' => 'field',
 'label' => __('Field'),
 'title' => __('Field'),
 'required' => true,
 'values' => [['value'=>'1', 'label'=> 'Use Default Value']],
 'checked' =>array(1)
 ]
);

• Jaimin Sutariya: Thank you Himanshu for the answer. If you have ever seen "Use default value" checkbox in Magento admin, it is connected to another field. When the checkbox is checked, the field uses default value and is disabled. When we uncheck the checkbox, the field gets enabled and you can change its value. Its not a separate checkbox field I want to add.
