spawn works as not expected

[NightBlaze]

Describe the bug

Still new to Rust so it's look like a bug in a wrapper of spawn.

In general Rust code I can write:

#[tokio::main]
async fn main() {
    let string = String::from("");
    tokio::spawn(async move {
        println!("{}", string);
        tokio::spawn(async move {
            println!("{}", string);
        });
    });
}

and it works as expected.

If I tried to write similar code in frb:

pub async fn foo() {
    let string = String::from("");
    flutter_rust_bridge::spawn(async move {
        // println!("{}", string); // Even if this line is commented
        flutter_rust_bridge::spawn(async move {
            println!("{}", string);
        });
    });
}

then I have an error use of moved value: "string" which is seems weird because I just move string to the second spawn's closure.

Steps to reproduce

pub async fn foo() {
    let string = String::from("");
    flutter_rust_bridge::spawn(async move {
        // println!("{}", string); // Even if this line is commented
        flutter_rust_bridge::spawn(async move {
            println!("{}", string);
        });
    });
}

Hmm interesting. frb's spawn

    fn spawn<F>(&self, future: F) -> JoinHandle<F::Output>
    where
        F: Future + Send + 'static,
        F::Output: Send + 'static,
    {
        self.0.spawn(future)
    }

calls tokio's spawn:

    pub fn spawn<F>(&self, future: F) -> JoinHandle<F::Output>
    where
        F: Future + Send + 'static,
        F::Output: Send + 'static,
    {
        ...
    }

A quick look does not reveal any differences... Indeed if there is any difference, we cannot write down self.0.spawn at all

Thus, could you please paste full error logs etc?

Found an issue. It's on my side. Sorry.

It's OK!
