Dart FFI: Binding C/C++/Go/Rust Libs For Dart
📖 Abstract:
- ✅ 基于
C FFI， 把C/C++/Rust库 binding 成 Dart 库， 供 Dart 调用。
💯 Related:
- ✅ #355
- ✅ #362
- ✅ #384
- ✅ #432
Dart FFI : 绑定其他语言(c/c++/go/rust)库使用
- ✅ dart 当前 lib 生态还不够丰富. 很多比较新的领域, 缺少 lib, 或者 lib 质量不够好.
- ✅ 需要借用其他语言的 lib 资源.
需求场景:
- ✅ 把成熟的 c/rust/zig/go 库 binding 给 dart 调用.
使用 Zig + FFI 配合 Flutter 方案:

- ✅ https://github.com/zigcc/forum/discussions/21
- ✅ 完整示例
dart 调用其他语言方案:
- ✅ 通用语言: https://dart.dev/guides/libraries/c-interop
- ✅ 针对 js: https://dart.dev/web/js-interop
原生插件:
- https://github.com/dart-lang/sdk/issues/45451
- https://juejin.cn/post/7005794537398337550/
- ✅ dart 官方已经在弃用 native extensions (method channel) 方式.
- ✅ 目前 flutter 还没完全废弃这个支持, 不过这个看起来是在日程上的了.
FFI(Foreign function interface):

官方工具:
- ✅ https://github.com/dart-lang/ffi
- ✅ https://pub.dev/packages/ffigen
- https://github.com/dart-lang/ffigen
- 辅助生成工具, 避免手写 c wrap 代码.

C++ + FFI => dart
问题:
- https://github.com/dart-lang/sdk/issues/42210
待实践的项目:
-
https://github.com/better-dart/wallet-core
-
https://developer.trustwallet.com/wallet-core/newblockchain
-
看起来, 已经用 c interface 包裹了 c++ 功能. 应该可以直接 binding 给 dart 使用.
项目使用列表:

https://developer.trustwallet.com/wallet-connect
Go + FFI => dart
- 不推荐使用 Go + CGo 的 FFI 方案.
- 尽量选择 Rust + FFI 方案.
一些讨论:

cgo: https://github.com/golang/go/wiki/cgo
方案:
mobile:
- https://medium.com/flutter-community/using-go-library-in-flutter-a04e3496aa05
- https://pkg.go.dev/golang.org/x/mobile/cmd/gomobile
- gomobile + jni + aar + platform channel(method channel)

Rust + FFI => dart
- 目前 rust 有些 FFI 的项目, 对 dart 比较友好.
- 可以优先了解+学习.

- 多谢提供这个 lib. 我学习一下哈.
- 顺便我又发现几个 rust ffi 支持 flutter 的 lib.
- 你可以了解一下.
- FFI 对 flutter 来说, 确实是非常重要的功能.

flutter 调用原生的另一种方案: platform channel
- ✅ 不推荐使用

- ✅ https://flutter.dev/docs/development/platform-integration/platform-channels
- ✅ https://api.flutter.dev/flutter/services/MethodChannel-class.html
一个非常好的实现 appflowy system design，目前看起来 rust 表现最好，但可惜我不会 rust，一直没发现 go 有很好的多平台方案，cgo 本身已经不简单了...
- 对. 这个项目, 是个不错的案例.
- rust + flutter 的典范.
- go + cgo 的模式, 不适合作 core lib 层, 给其他语言跨平台复用.
- core lib 跨平台, 还是建议使用 rust/c/c++.
