Higher-level Plugin api akin to flutter-rs

[maxjoehnk]

I'm working on an application written in rust with flutter as the UI and was using flutter-rs until now.
I've implemented some custom channels and flutter-rs has a nice abstraction for flutter plugins as well as the different channel types.

Do you have any intentions to implement something similar?

Have you taken look at the examples? There are rust channel handlers registered with message manager.

https://github.com/nativeshell/examples/blob/main/src/platform_channels.rs
https://github.com/nativeshell/examples/blob/main/src/file_open_dialog.rs

If you want to you can even package your handler as a crate, all you'd need as an entry point is for your plugin to register with message manager.

Yeah I've seen the examples. But if you compare the api to the flutter-rs api it's way more cumbersome to work with.
In flutter-rs all you need to do is implement the trait MethodCallHandler and then you can register it with the engine.
There is also a Plugin trait which allows registration of channels to the engine.

For reference here you can find the usage of the Plugin trait and here you can see how the usage of the MethodCallHandler trait looks like.

I see. Would something like this work?

The Plugin struct is fairly easy to implement on top of existing machinery, but I don't mind including it if it makes things more convenient.

So it could be something like this

https://github.com/nativeshell/nativeshell/blob/nativeshell_plugin/nativeshell/src/shell/method_channel.rs

and this is how it would be used:

https://github.com/nativeshell/examples/blob/nativeshell_plugin/src/file_open_dialog.rs
https://github.com/nativeshell/examples/blob/nativeshell_plugin/src/platform_channels.rs
https://github.com/nativeshell/examples/blob/nativeshell_plugin/src/main.rs
