facebook_sdk_flutter allows you to fetch deep links, deferred deep links and log facebook app events.

This was created using the latest facebook SDK to include support for iOS 14. The plugin currently supports app events and deeps links for iOS and Android.

First of all, if you don't have one already, you must first create an app at Facebook developers: https://developers.facebook.com/

Get your app id (referred to as [APP_ID] below)

• If your code does not have CFBundleURLTypes, add the following just before the final element:

 <key>CFBundleURLTypes</key>
    <array>
      <dict>
      <key>CFBundleURLSchemes</key>
      <array>
        <string>fb[APP_ID]</string>
      </array>
      </dict>
    </array>
    <key>FacebookAppID</key>
    <string>[APP_ID]</string>
    <key>FacebookDisplayName</key>
    <string>[DISPLAY_NAME]</string>
    <key>FacebookAutoLogAppEventsEnabled</key>
    <true/>
    <key>FacebookAdvertiserIDCollectionEnabled</key>
    <true/>

• Add the following to your strings.xml file

<string name="facebook_app_id">[APP_ID]</string>
<string name="fb_login_protocol_scheme">fb[APP_ID]</string>

• Add the following meta tag to the application element in AndroidManifest.xml

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>

• Add the following element in AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET"/>

• Don't forget to replace [APP_ID] with your Application ID
