Suppose you are middle of controller or repository file and you want check if $isChecked has TRUE value or not, and if has false value you want throw error:

In controller or repository file:

return (new CustomValidationError)->setError('isChecked','HERE_TYPE_YOUR_ERROR_MESSAGE')->throwErrors();

Response:

{
    "message": "The given data was invalid.",
    "errors": {
        "isChecked": [
            "HERE_TYPE_YOUR_ERROR_MESSAGE"
        ]
    }
}
