Use case

This is similar to #185687

We track the connectionOptions in FlutterSceneLifecycle.mm:

flutter/engine/src/flutter/shell/platform/darwin/ios/framework/Source/FlutterSceneLifeCycle.mm

Lines 34 to 36 in c243752

@property(nonatomic, strong) UISceneConnectionOptions* connectionOptions;
@property(nonatomic, assign) BOOL sceneWillConnectEventHandledByPlugin;
@property(nonatomic, assign) BOOL sceneWillConnectFallbackCalled;

Proposal

FlutterSceneLifecycle.mm is associated with the scene delegate. However, connectionOptions should be associated per UIScene rather than UISceneDelegate.

About the other 2 flags (sceneWillConnectEventHandledByPlugin and sceneWillConnectFallbackCalled): I am not sure what they are used for yet. TBD
