Flutter环境配置教程 | Rust环境配置教程

新建一个全新的Flutter项目并运行：

flutter create example && cd example && flutter run

在Flutter项目根目录新建一个Rust项目：

cargo new native --lib

目录结构大概是这样的：

接下来，将这两行添加到 Cargo.toml：

[lib]crate-type = ["staticlib", "cdylib"][dependencies]flutter_rust_bridge = "1.78.0"[build-dependencies]flutter_rust_bridge_codegen = "1.78.0"

 在native/src目录新建一个api.rs

添加以下示例代码：

//api.rspub fn hello() -> String {    format!("{}", "你好,Rust!")}

   lib.rs

//lib.rsmod api;

安装flutter_rust_bridge_codegen：

cargo install flutter_rust_bridge_codegen

修改Flutter项目的pubspec.yaml配置文件：

 pubspec.yaml 配置文件完整代码：
