Unhandled Exception: Bad state; out-of-sync code #1926

Closed dm107 closed 3 weeks ago

dm107 commented 3 weeks ago

Describe the bug

Running the flutter app results in an unhandled exception when using reqwest (async and sync). The reason is: content hash on Dart side (...) is different from Rust side (...) But the compilation of Rust passed without errors, as well flutter_rust_bridge_codegen generate After removing the reqwest client everything works fine.

Steps to reproduce

  1. Create a new app with flutter_rust_bridge_codegen create my_app
  2. Add the following code to simple.rs 
    
use reqwest::blocking::Client;

[flutter_rust_bridge::frb(sync)] // Synchronous mode for simplicity of the demo

pub fn greet(name: String) -> String { format!("Hello, {name}!") }

[flutter_rust_bridge::frb(init)]

pub fn init_app() { // Default utilities - feel free to customize flutter_rust_bridge::setup_default_user_utils(); }

pub struct SimpleApi { client: Client, }

impl SimpleApi { pub fn new() -> Self { Self { client: Client::new(), } } }

3. Add reqwest to dependencies

reqwest = { version = "0.12.4", features = ["blocking", "json"] }

4. Generate *flutter_rust_bridge_codegen generate*
5. Run *flutter run*

### Logs

```shell
E/flutter (17651): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Bad state: Content hash on Dart side (1147114678) is different from Rust side (-1918914929), indicating out-of-sync code. This may happen when, for example, the Dart code is hot-restarted/hot-reloaded without recompiling Rust code. (Note: This is just a sanity check. Even if content hash does not change, the code may still change and needs to be recompiled)

Hi! Thanks for opening your first issue here! :smile:

fzyzcjy commented 3 weeks ago

Hi, could you please share a minimal reproducible sample, and also show generate's log? That looks like a bug. In normal scenario, the content hash will be updated in both Rust generated code and Dart generated code, so they should be in sync.

Done!

What kind of reproducible sample do you need? Are my steps not sufficient?

And by the way. I've noticed that generate --watch doesn't seem to create any new files when I add a new Rust file. I have to restart generate

I must have been too tired and did not realize your full reproducible steps! I will check it now.

fzyzcjy commented 3 weeks ago

I cannot reproduce it, both have same hash:

(base) ➜  my_app cat rust/src/frb_generated.rs | grep HASH
pub(crate) const FLUTTER_RUST_BRIDGE_CODEGEN_CONTENT_HASH: i32 = 1147114678;
(base) ➜  my_app cat lib/src/rust/frb_generated.dart | grep ContentHash
  int get rustContentHash => 1147114678;

Could you please try to run generate again and flutter run?

dm107 commented 3 weeks ago

I have the same hash, so the my error confused me. (A hash error is still being reported) Now I have recreated the project and found the reason. It occurs when executing flutter run Its due openSSL

My standalone Rust is working, I need to find out why... So I think its not a flutter_rust_bridge problem.

fzyzcjy commented 3 weeks ago

I see, then it looks like maybe e.g. cargokit does not stop flutter run under compilation error.

So I think its not a flutter_rust_bridge problem.

Totally agree!
