How to generate proper asynchronous function bindings?

[mintsuku]

I am trying to build an async request with flutter_rust_bridge. Here is my code:

pub async fn greeting_from_rust() -> String {
    match reqwest::get("https://www.example.com").await {
        Ok(resp) => match resp.text().await {
            Ok(text) => text,
            Err(_) => "Error occurred while reading the response text.".to_string(),
        },
        Err(_) => "Error occurred while making the request.".to_string(),
    }
}

My problem is the generated code in bridge_generated.rs throws an error:

the trait bound `impl Future<Output = String>: IntoIntoDart<_>` is not satisfied
the following other types implement trait `IntoIntoDart<D>`:
  <bool as IntoIntoDart<bool>>
  <i8 as IntoIntoDart<i8>>
  <i16 as IntoIntoDart<i16>>
  <i32 as IntoIntoDart<i32>>
  <i64 as IntoIntoDart<i64>>
  <usize as IntoIntoDart<usize>>
  <u8 as IntoIntoDart<u8>>
  <u16 as IntoIntoDart<u16>>

The line this error occurs on is:

    FLUTTER_RUST_BRIDGE_HANDLER.wrap::<_, _,  _, _, String>(

How do i fix this error? What am i doing improper?

Just wait for v2 (which hopefully can be released within a week or two), with full support for async :)

Okay cool no problem, in the mean time ill just write non async code i won't die lmao
