Answer 1

as the friendly doc mentions it, i believe you got to build your app.

https://flutter.dev/docs/get-started/web#build

Run the following command to generate a release build:

flutter build web

This populates a build/web directory with built files, including an assets directory, which need to be served together.

how golang code should look like?

like any other regular HTTP golang server.

http.Handle("/build/web/", http.StripPrefix("/build/web/", http.FileServer(http.Dir("build/web"))))

http.ListenAndServe(":8080", nil)

package main

import (
    "flag"
    "log"
    "net/http"
)

func main() {
    port := flag.String("p", "8181", "port to serve on")
    directory := flag.String("d", "web", "the directory of static file to host")
    flag.Parse()
    http.Handle("/", http.FileServer(http.Dir(*directory)))
    log.Printf("Serving %s on HTTP port: %s\n", *directory, *port)
    log.Fatal(http.ListenAndServe(":"+*port, nil))
}

Just copy web folder to your's go app.

Answer 3

Server will be hosted at http://localhost:8080/ and make sure you don't add slash/ in file path

package main

import (
    "log"
    "net/http"
)

func main() {
    // Serve Flutter app files from the build/web directory
    http.Handle("/", http.FileServer(http.Dir("client/build/web")))

    // Start the server on port 8080
    log.Fatal(http.ListenAndServe(":8080", nil))
}
