[Feature request] Watch() widget with finer grain control like ValueListenableBuilder

[scalz]

Hello,

Thank you for sharing your work. It shares some concepts with Mobx and Solidart. I like to use Mobx, or vanilla ValueNotifier etc but your implementation is interesting too :)

What do you think about adding finer grain control to Watch() widget, like ValueListenableBuilder can do ? They added this option recently in Mobx Observer() widget.

Watch((context, Widget? child) {
    return MyWidget('$counter', child: child!);
  },
  child: DoNotRebuildWidget(...),
)

or like these but currently, Watch builder is required

Watch(
  builderWithChild: (context, child) {
    return MyWidget('$counter', child: child!);
  },
  child: DoNotRebuildWidget(...),
)

Watch.withChild(
  builderWithChild: (context, child) {
    return MyWidget('$counter', child: child!);
  },
  child: DoNotRebuildWidget(...),
)

If you split your Widgets and logic into smaller parts this can perhaps be worked around. I can appreciate this for convenience and it is very useful and handy with animations that also have a child does not change during the animation.

However, I also like that currently I can just use IDE feature and the standard "Wrap with Builder" and change it to "Watch" with its current signature.

I like the proposal, but I would prefer an addition that does not to break Watch current signature, also for backwards API compatibility. Consider adding another watcher for this.

You can make any signal into a ValueListenable and use with ValueListenenableBuilder if you prefer: https://rodydavis.github.io/signals.dart/reference/value-listenable/

But the intention of the watch widget is to be as minimal as possible

Good point :) And I can make a custom watch widget if I really need it, that's fine too. Thx

I'm going to close this for now, but going to convert this to a discussion!
