FlutterViewController.engineAllowHeadlessExecution drives whether an implicitly-created FlutterEngine is createed with allowHeadlessExecution, which causes the engine to tear down its shell when its view controller deallocs. We didn't previously have any test coverage for this.

The property was added in flutter-team-archive/engine#19458 with the intent of being configured from a XIB, and since it's read-only, Interface Builder's User Defined Runtime Attributes reach it by setting the synthesized ivar through key-value coding. Declaring a getter, or marking it @dynamic, would leave storyboards unable to set it, which would break it for end-users.

We now check:

  • that the property can be set via setValue:forKey: (check KV support)
  • that an implicitly-created engine picks it up

I added allowHeadlessExecution from the extension in FlutterEngine.mm to the FlutterEngine (Test) category so we can check it in tests.

Issue: #112232

Code Review

This pull request adds the allowHeadlessExecution property to FlutterEngine and introduces unit tests to verify that engineAllowHeadlessExecution can be configured via Key-Value Coding (KVC) on FlutterViewController and is correctly inherited by implicitly created engines. The feedback suggests enhancing the KVC test by asserting that the lazily initialized engine also receives the updated allowHeadlessExecution value.

To fully verify the primary storyboard/XIB integration use case, we should also assert that the implicitly created engine actually receives the allowHeadlessExecution value set via Key-Value Coding (KVC). Adding an assertion for viewController.engine.allowHeadlessExecution ensures that the KVC-configured property correctly propagates to the lazily initialized engine.

  [viewController setValue:@YES forKey:@"engineAllowHeadlessExecution"];
  XCTAssertTrue(viewController.engineAllowHeadlessExecution);
  XCTAssertTrue(viewController.engine.allowHeadlessExecution);
}

This engine isn't "lazily initialised". initWithProject: calls sharedSetupWithProject: synchronously which builds the engine right there and immediately reads engineAllowHeadlessExecution.

Setting it later does nothing -- the engine was already created!

Added a note in the doc comment to make that clearer.
