Using functions as 'family' parameters correctly (operator==, hashCode)

[wujek-srujek]

Here https://riverpod.dev/docs/concepts/modifiers/family#parameter-restrictions it says that parameters need to implement operator== and hashCode for 'family' to work. How would I do this correctly if I wanted a family which receives a callback as its parameter?

final provider = Provider.autoDispose.family<String, void Function()>(
  (state, callback) => ...,
);

I think inline lambdas or member methods, won't work, but global functions (or static ones) would - is this correct? I.e. I need to use the latter if I want 'family' to work correctly?

You could try making sure that you're reusing an existing function instance.

So:

provider(() => ...)

is obviously a no-go.

But you could store that () => somewhere and reuse it in different places

Although I'd suggest finding a different approach.
