Changing the flow from 1 to 2, what is wrong

[107295472]

lazy_static! {
    static ref SEND_TO_DART_LOGGER_STREAM_SINK: RwLock<Option<StreamSink<ResMsg>>> =
        RwLock::new(None);
}
fn cmd_msg(s: ResMsg) {
    if let Some(sink) = &*SEND_TO_DART_LOGGER_STREAM_SINK.read() {
        sink.add(s);
    }
}
pub fn create_msg(sink: StreamSink<ResMsg>) {
    let mut guard = SEND_TO_DART_LOGGER_STREAM_SINK.write();

    *guard = Some(sink);
}

this error originates in the macro $crate::frb_generated_stream_sink which comes from the expansion of the macro flutter_rust_bridge::frb_generated_boilerplate (in Nightly builds, run with -Z macro-backtrace for more info)

Hi, could you please check your ResMsg type? For example, if it is not of lifetime static, then it will not work, because stream items needs to live arbitrarily long.

#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct ResMsg<'a> {
    pub percentage: f32,
    pub count: i32,
    pub message: &'a str,
    pub code: i32,
}

Happy to see it is solved (closed)!
