[Bug] The parameter 'ptr' of the method 'NativeWire.store_dart_post_cobject' has type 'int', which does not match the corresponding type #1339

Describe the bug

I am using the template from https://github.com/Desdaemon/flutter_rust_bridge_template Running flutter_rust_bridge_codegen works just fine. However, there is an issue with the generated code, which causes a compilation error when running flutter run

Integrating flutter_rust_bridge into an existing project yields the same result.

To Reproduce

Download the template and cd into it. Run flutter_rust_bridge_codegen --rust-input native/src/api.rs --dart-output ./lib/bridge_generated.dart --dart-decl-output ./lib/bridge_definitions.dart Followed by flutter run.

Expected behavior

The Flutter application compiles and runs.
