Introduce the PipelineOwner tree #122231

goderbauer · 2023-03-08T20:47:14Z

Implements the PipelineOwner tree as specified in https://flutter.dev/go/multiple-views.

/// [PipelineOwner]s can be organized in a tree to manage multiple render trees,

/// [PipelineOwner]s are organized in a tree to manage multiple render trees,

Aren't they always arranged this way (even a single main view can have subviews).

I wanted to express here that the PipelineOwner class can also be used stand-alone. It fully functions if it is not part of a tree, for example for the use case mentioned above where you create another pipeline owner to manage off-screen objects. You are not required to turn them into a tree or attach them to any (existing) tree. Of course, one could argue, that just having a single node (the root) is also a form of tree...

Oh, OK, ignore my comment then.

We don't need to be as pedantic as all that. :-)

Suggested change

bool _debugDoingChildrenLayout = false;

bool _debugDoingChildLayout = false;

...because it just reads better. I'd either say "I'm doing child layout" or "I'm laying out children", but not "I'm doing children layout".

Maybe wrap this line

Why use adopt/drop? They're not really opposites of each other. Why not addChild/removeChild? If you want to use adopt, then the opposite is probably "abandon". Which feels a bit bleak. :-)

That's the terminology we use for every other tree node class in the framework:

https://master-api.flutter.dev/flutter/foundation/AbstractNode/adoptChild.html

https://master-api.flutter.dev/flutter/foundation/AbstractNode/dropChild.html

Sigh. Okay, consistency is important, but it's too bad that they aren't opposites.

All comments are addressed and all failing checks should pass now. PTAL @gspencergoog.
