[Bug] Unable to generate dart bindings with enums variants that contain other types #813

Closed justinmoon closed 1 year ago

justinmoon commented 1 year ago

Describe the bug

I have a flutter app where the actual app is in apps/<app-name>, which contains a package that uses flutter_rust_bridge in packages/api_client/lib/src/rust_bridge.

I have the following enum in api.rs:

pub enum Foo {
    bar(u64),
}

pub fn get_foo() -> Foo {
    Foo::bar(10)
}

From the rust_bridge folder, I attempt to generate bindings with the following command:

$ flutter_rust_bridge_codegen \
        -r src/api.rs \
        -d bridge_generated.dart \
        -c ../../../../../apps/something/ios/Runner/bridge_generated.h
...
Unhandled exception:
Bad state: Unable to generate package graph, no `/Users/justin/something/mobile/packages/api_client/.dart_tool/flutter_gen/pubspec.yaml` found.
#0      _pubspecForPath (package:build_runner_core/src/package_graph/package_graph.dart:232:5)

<asynchronous suspension>

If the enum isn't nested at all this doesn't happen. For example, the following works just fine:

pub enum Foo {
    bar
}

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

fzyzcjy commented 1 year ago

looks like flutter_gen not installed

fzyzcjy commented 1 year ago

hmm looks like build_runner throws error, so maybe it is a bug/misuse there

Hmmm. But I get this same error when comment out Foo and get_foo ... so maybe this method of installing flutter_gen isn't right?

The pubspec.lock file has changed since the .dart_tool/package_config.json file was generated, please run "flutter pub get" again.

I re-ran flutter pub get a few times from apps/app-name and packages/api_client and still get the same error.

fzyzcjy commented 1 year ago

hmm maybe output debug logs and see what command it runs and see what is the problem. feel free to PR after you find the bug!

justinmoon commented 1 year ago

The root problem was that I had a conflicting version ffigen installed by one of my dependencies.
