Cargokit

flutter_rust_bridge uses Cargokit for seamless integration of cargo build with flutter applications and packages.

Cargokit remains the default flutter_rust_bridge_codegen create/integrate backend for compatibility with existing projects and older Flutter/Dart SDKs. The Native Assets backend is available through --integration-backend native-assets.

Cargokit Details

Please refer to its documentation for how to use it. The original GitHub repository is https://github.com/irondash/cargokit. That repository has been archived; flutter_rust_bridge now uses the fork maintained by the flutter_rust_bridge team for template and submodule updates. In addition, it has a companion blog about how to integrate it at https://matejknopp.com/post/flutter_plugin_in_rust_with_no_prebuilt_binaries/.

The following links may also be useful for customizations:

• Configuration: https://github.com/irondash/cargokit/blob/main/docs/architecture.md#configuring-cargokit
• Use precompiled binaries (instead of default compile-on-the-fly): https://github.com/irondash/cargokit/blob/main/docs/precompiled_binaries.md

For new projects that can require a recent Flutter/Dart SDK, consider the Native Assets backend.
