[Bug] Issue with passing arguments from rust to flutter? #1431

Closed kljohnsonn closed 9 months ago

kljohnsonn commented 10 months ago

Describe the bug

When trying to pass an argument like (url: String) i seem to encounter an error on the flutter side of my code telling me that my .so, .dll or .dylib has no symbol: Screenshot from 2023-12-06 19-47-12

The rust code i used to generate this was:

use std::ffi::{CStr, CString};

use reqwest;
use tokio;

pub fn greeting_from_rust(url: String) -> String {
    match reqwest::blocking::get(url) {
        Ok(resp) => match resp.text() {
            Ok(text) => text,
            Err(_) => "Error occurred while reading the response text.".to_string(),
        },
        Err(_) => "Error occurred while making the request.".to_string(),
    }
}

I have no clue what the issue is, im very new so im not sure how i am suppose to pass arguments.

To Reproduce

Just reuse my code in your .api.rs file and use the codegen

Expected behavior

No error should appear and my code should display a http response

Firstly, maybe ensure your generated binary (.so/.dylib/whatever) is up-to-date.

Secondly, v2 will handle all these compilation for you :)

fzyzcjy commented 9 months ago

Hi, v2 has been released, and feel free to create issues if the error still exists (I guess it will be fixed since v2 handles the symbols etc by default)!
