MacOS环境下Flutter与Golang交互无响应问题求助

MacOS环境下尝试实现Flutter与Golang交互，让程序后台运行。已解决「Failed to load library」和「Failed to lookup symbol of Start and Stop」问题，但当前点击Flutter页面的Start/Stop按钮时，仅能打印Flutter的debugPrint内容，Golang代码中的日志完全无输出，二者未成功建立交互。已尝试官方Codelabs提供的方法，仍无法解决问题，寻求帮助。

Golang代码 #

package main

import "C"
import (
    "fmt"
    "log"
)

//export Start
func Start() {
    log.Println("My Go Code Start run successfully")
}

//export Stop
func Stop() {
    log.Printf("My Go Code Stop run successfully")
}

func main() {
    fmt.Printf("My Go Code Main run successfully\n")
    Start()
    Stop()
}

编译命令 #

使用以下命令编译Golang代码为动态库：

go build -o main.dylib -buildmode=c-shared main.go
