Add the star rating component from another package to the property tile component

Replace PropertyController.cls and propertyTile.html from your project with below snippet
PropertyController.cls
public with sharing class PropertyController {
@AuraEnabled(cacheable=true)
public static Property__c[] getPropertyList( String searchKey, Decimal maxPrice, Integer minBedrooms, Integer minBathrooms ) {
String key = '%' + searchKey + '%';
return [
SELECT Id, address__c, city__c, state__c, description__c, price__c, baths__c, beds__c, thumbnail__c, location__latitude__s, location__longitude__s, Rating__c, Features__c
FROM property__c
WHERE (city__c LIKE :key OR tags__c LIKE :key) AND price__c <= :maxPrice AND beds__c >= :minBedrooms AND baths__c >= :minBathrooms
// WITH SECURITY_ENFORCED
ORDER BY price__c
LIMIT 100
];
}
​
@AuraEnabled(cacheable=true)
public static PagedResult getPagedPropertyList( String searchKey, Decimal maxPrice, Integer minBedrooms, Integer minBathrooms, Integer pageSize, Integer pageNumber ) {
maxPrice = Decimal.valueOf(maxPrice + '');
minBedrooms = Integer.valueOf(minBedrooms + '');
minBathrooms = Integer.valueOf(minBathrooms + '');
pageSize = Integer.valueOf(pageSize + '');
pageNumber = Integer.valueOf(pageNumber + '');
​
Integer pSize = (Integer) pageSize;
String key = '%' + searchKey + '%';
Integer offset = ((Integer) pageNumber - 1) * pSize;
PagedResult result = new PagedResult();
result.pageSize = pSize;
result.pageNumber = (Integer) pageNumber;
result.totalItemCount = [
SELECT COUNT()
FROM property__c
WHERE (city__c LIKE :key OR tags__c LIKE :key) AND price__c <= :maxPrice AND beds__c >= :minBedrooms AND baths__c >= :minBathrooms
];
result.records = [ SELECT Id, address__c, city__c, state__c, description__c, price__c, baths__c, beds__c, thumbnail__c, Rating__c,Features__c
FROM property__c
WHERE (city__c LIKE :key OR tags__c LIKE :key) AND price__c <= :maxPrice AND beds__c >= :minBedrooms AND baths__c >= :minBathrooms
// WITH SECURITY_ENFORCED
ORDER BY price__c
LIMIT :pSize
OFFSET :offset
];
return result;
}
​
@AuraEnabled(cacheable=true)
public static List<ContentVersion> getPictures(Id propertyId) {
List<ContentDocumentLink> links = [
SELECT Id, LinkedEntityId, ContentDocumentId
FROM ContentDocumentLink
WHERE
LinkedEntityId = :propertyId
AND ContentDocument.FileType IN ('PNG', 'JPG', 'GIF')
// WITH SECURITY_ENFORCED
];
​
if (links.isEmpty()) {
return null;
}
​
Set<Id> contentIds = new Set<Id>();
​
for (ContentDocumentLink link : links) {
contentIds.add(link.ContentDocumentId);
}
​
return [
SELECT Id
FROM ContentVersion
WHERE ContentDocumentId IN :contentIds AND IsLatest = TRUE
// WITH SECURITY_ENFORCED
ORDER BY CreatedDate
];
}
}

Install 2 packages to playground 2 using CLI command sfdx force:package:install​

sfdx force:package:install -p 04t6F000001ZL7yQAG -w 30 --apexcompile package --securitytype AdminsOnly --noprompt -u playground-2
​
sfdx force:package:install -p 04t5I000001ecttQAA -w 30 --apexcompile package --securitytype AdminsOnly --noprompt -u playground-2
​
sfdx force:package:install -p 04t6F000001D6LOQA0 -w 30 --apexcompile package --securitytype AdminsOnly --noprompt -u playground-2

Deploy all changes to playground 2 using sfdx force:source:deploy command

Use the sfdx force:source:deploy command to deploy all changes to playground 2. Once the metadata is successfully committed, commit your changes to the repo.

Recap

Packages deliver functionality with a defined lifecycle. Salesforce has many forms of packaging, what we are focused is on 2GP or Second-Generation Packaging, which can be used for ISV as a managed package or for others using unlocked packages.
By completing the challenge, you have understood, how to utilise a managed package from AppExchange for your development and deploying metadata/code that depends on these components
