Facebook App Events guides for Flutter

Flutter-specific answers to the problems that actually stop people. Meta's documentation is platform generic and never mentions Flutter. These pages fill that gap, and link to Meta for the canonical specification.

• Facebook "Please Upgrade SDK" warning in Events Manager (Flutter)

  Events Manager says to update to Facebook SDK 4.34.0 or higher when yours is already newer. Why the warning appears, and what to do instead.

• Facebook events not showing in Events Manager (Flutter)

  Your Flutter app logs events and Events Manager shows nothing. Work through the causes in order: delay, configuration, transport, attribution.

• Where the Facebook client token goes in a Flutter app

  The Facebook client token is not your app id, and on Android it needs two files rather than one. Where to get it and where it goes.

• What Facebook App Events covers in Flutter, and what it does not

  A reference for the facebook_app_events plugin: its 1:1 mapping to the native SDKs, the APIs it leaves out, and the rule that drops events.

• Which Facebook SDK version a Flutter app gets, and what controls it

  The plugin pins the Facebook SDK major and lets the minor float. The constraint on each platform, and the version floors you have to meet.

• Swift Package Manager setup for the Facebook SDK in Flutter

  The plugin ships a Swift package manifest whose library product uses hyphens where the plugin name uses underscores. What to check when it fails.
