Flutter open facebook link in facebook app android & ios

In my app i have stored Facebook url's. I want to open them in facebook app not in browser. I tried using flutter_url_launcher package but it open the link in default browser ... What i want is to open the link directly into the facebook app . Can anyone suggest any solution or package to help me out of this situation?

I also used the solution from the link @ruelluna mentioned.

Per current version, the below code worked for me:

String fbProtocolUrl;
if (Platform.isIOS) {
  fbProtocolUrl = 'fb://profile/page_id';
} else {
  fbProtocolUrl = 'fb://page/page_id';
}

String fallbackUrl = 'https://www.facebook.com/page_name';

try {
  bool launched = await launch(fbProtocolUrl, forceSafariVC: false);

  if (!launched) {
    await launch(fallbackUrl, forceSafariVC: false);
  }
} catch (e) {
  await launch(fallbackUrl, forceSafariVC: false);
}

Also, make sure Info.plist file contains the following:

 <array> 
        <dict>
            <key>CFBundleURLSchemes</key>
            <array>
                <string>fb[your_page_id]</string>
            </array>
        </dict>
    </array>
