Built-in controllers dispose

[busslina]

Is there a reason on built-in controllers (TextEditingController, FocusNode and FocusScopeNode) to not being auto-disposed?

For this purpose I also envision that would be helpful to have a built-in side effect that execute once (like callonce), return the value and also execute on disposing. Similar to use.effect but this last one is void.

They should be getting disposed; see https://github.com/GregoryConrad/rearch-dart/blob/main/packages/flutter_rearch/lib/src/side_effects/text_editing_controller.dart

After looking at the current FocusNode effect source they aren't getting disposed. That's a bug.

Yea, like a:

use.disposable(FocusNode.new, (node) => node.dispose());

Assuming Dart's type inference doesn't screw that up, that seems like a solid idea to me (and could be used to fix the FocusNode effects

use.disposable(FocusNode.new, (node) => node.dispose());

I like it.
