Cannot implement custom async runtime

[Tae Hagen]

Describe the bug

According to the docs, in v2 you should be able to implement your own BaseAsyncRuntime. However, I created a struct that implements it, but it is never called. I think I need to declare a new executor, but there appears to be no way to access all the types I need to do that because many of them are not exported. How can I provide a custom async runtime? I need to manage it's lifecycle outside of the context of this project for background work when the dart VM is not active.

Thank you!

Steps to reproduce

Hint: A simple way to reproduce is to clone and modify the https://github.com/fzyzcjy/flutter_rust_bridge/tree/master/frb_example/dart_minimal example package according to your needs.

Hi! Thanks for opening your first issue here! 😄

Hmm then that looks like a bug! Feel free to PR to fix it (export needed variables), or alternatively I will fix it in the (hopefully within a week) next batch.

P.S. #1848 is also working on async runtime

Could I instead change the DefaultExecutor type to have another type parameter, one for the async runtime?

Sure, you are free to use whatever executor you like.
