In iOS, how can I get the contact shared from "Recent" calls list to my app in Flutter?

Question

Please excuse me if I sound stupid, I'm new to flutter.

I have started learning flutter recently and wanted to create an app where anyone can share a contact from the "Recent" calls list to my app. I'm following this blog post which allows text share from any other app to my app.

What I have done so far:

1. This is my plist file, added the public.vcard to allow my app to appear on the tap of "Share Contact".

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>NSExtension</key>
    <dict>
        <key>NSExtensionAttributes</key>
        <dict>
        <key>NSExtensionActivationRule</key>
        <string>
            SUBQUERY (
            extensionItems, $extensionItem,
            SUBQUERY (
            $extensionItem.attachments, $attachment,
            ANY $attachment.registeredTypeIdentifiers UTI-CONFORMS-TO "public.vcard"
            ).@count >= 1
            ).@count > 0
        </string>
        </dict>
        <key>NSExtensionMainStoryboard</key>
        <string>MainInterface</string>
        <key>NSExtensionPointIdentifier</key>
        <string>com.apple.share-services</string>
    </dict>
</dict>
</plist>

2. Here's my ShareViewController.swift

import Social
import MobileCoreServices

class ShareViewController: SLComposeServiceViewController {

    override func isContentValid() -> Bool {
        // Do validation of contentText and/or NSExtensionContext attachments here
        print("Something is not right")
        return true
    }

    override func didSelectPost() {
        // This is called after the user selects Post. Do the upload of contentText and/or NSExtensionContext attachments.
    
        // Inform the host that we're done, so it un-blocks its UI. Note: Alternatively you could call super's -didSelectPost, which will similarly complete the extension context.
        let sharedSuiteName: String = "group.com.thelogicalbeing.whatsappshare"
            let sharedDataKey: String = "SharedData"
            let extensionItem = extensionContext?.inputItems[0] as! NSExtensionItem
            let contentTypeText = kUTTypeText as String // Note, you need to import 'MobileCoreServices' for this
            for attachment in extensionItem.attachments! {
                print(attachment)
                if attachment.hasItemConformingToTypeIdentifier(contentTypeText) {
                    attachment.loadItem(forTypeIdentifier: contentTypeText, options: nil, completionHandler: {(results, error) in
                        if let sharedText = results as! String? {
                            if let userDefaults = UserDefaults(suiteName: sharedSuiteName) {
                                userDefaults.set(sharedText, forKey: sharedDataKey)
                            }
                        }
                    })
                }
            }

            self.extensionContext!.completeRequest(returningItems: [], completionHandler: nil)

    }

    override func configurationItems() -> [Any]! {
        // To add configuration options via table cells at the bottom of the sheet, return an array of SLComposeSheetConfigurationItem here.
        return []
    }

}

3. Here's my AppDelegate.swift

import UIKit
import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    let sharedSuiteName: String = "group.com.thelogicalbeing.whatsappshare"
    let sharedDataKey: String = "SharedData"

    let controller: FlutterViewController = window?.rootViewController as! FlutterViewController
    let methodChannel = FlutterMethodChannel(name: "com.thelogicalbeing.whatsappshare", binaryMessenger: controller.binaryMessenger)

    methodChannel.setMethodCallHandler({
        (call: FlutterMethodCall, result: @escaping FlutterResult) -> Void in
        if call.method == "getSharedData" {
            if let prefs = UserDefaults(suiteName: sharedSuiteName) {
                if let sharedText = prefs.string(forKey: sharedDataKey) {
                    result(sharedText);
                }
                // clear out the cached data
                prefs.set("", forKey: sharedDataKey);
            }
        }
    })

    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

What I'm trying to achieve is that I need to receive the phone number and display it in my app.

Don't know how to proceed. Any help will be appreciated.

Solution

1- Apple does not allow fetching call logs on iOS!

You can fetch all contacts with all their information. But not the calls log.

2- On Android you can use the pub.dev dependency plugin call_log to do that.

Can you share the blog post? Also might want to have a look at this -pub.dev/packages/receive_sharing_intent

Not interested in fetching call logs. From the phone app of the iPhone there is a share option using which I can share that contact to my app. I was able to get my app in that share option. I was just not able to get the card from there.
