I created a new EAV attribute using this code :

'information',
 [
 'group' => 'Content',
 'type' => 'int',
 'default' => null,
 'global' => MagentoEavModelEntityAttributeScopedAttributeInterface::SCOPE_GLOBAL,
 'visible' => false
 ]

PS: I added this attribute to the product form

this attribute is by default hidden, but I want to visible it after a condition, is there any method to do that?

You can easily do that using a plugin. Try following way to doing this. Following example will hide product name. For your custom attribute you need to modify plugin code.

app/code/SR/MagentoCommunity/etc/adminhtml/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
 <type name="MagentoCatalogUiDataProviderProductFormModifierGeneral">
 <plugin name="sr_attribute_visibility"
 type="SRMagentoCommunityPluginCatalogUiDataProviderProductFormModifierGeneral" sortOrder="1"/>
 </type>
</config>

app/code/SR/MagentoCommunity/Plugin/Catalog/Ui/DataProvider/Product/Form/Modifier/General.php

<?php
namespace SRMagentoCommunityPluginCatalogUiDataProviderProductFormModifier;


class General

 public function afterModifyMeta(
 MagentoCatalogUiDataProviderProductFormModifierGeneral $subject,
 $meta
 ) 
 // add your condition
 $meta['product-details']['children']['container_name']['children']['name']['arguments']['data']['config']['visible'] = 0;
 // print $meta and check your custom attribute index.
 return $meta;
 

[Update]

Suppose information is text attribute. Now modify following way:

<?php
namespace SRMagentoCommunityPluginCatalogUiDataProviderProductFormModifier;


class General

 public function afterModifyMeta(
 MagentoCatalogUiDataProviderProductFormModifierGeneral $subject,
 $meta
 ) 
 // add your condition
 if (isset($meta['product-details']['children']['container_information'])) 
 $meta['product-details']['children']['container_information']['children']['information']['arguments']['data']['config']['visible'] = 0;
 

 return $meta;
 

PS: the attribute visibility should be by default: true (false don't work)
