go - fyne GUI compile to Web Assembly failed

Question

i was checking the possibility to use fyne in browser using Web Assembly , but i am getting error ...
main.go :

package main

import (
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/container"
    "fyne.io/fyne/v2/widget"
)

func main() {
    a := app.New()
    w := a.NewWindow("Hello")

    hello := widget.NewLabel("Hello Fyne!")
    w.SetContent(container.NewVBox(
        hello,
        widget.NewButton("Hi!", func() {
            hello.SetText("Welcome :)")
        }),
    ))

    w.ShowAndRun()
}

i ran this command ,

GOOS=js GOARCH=wasm go build -o main.wasm main.go 

Output (error) :

    imports fyne.io/fyne/v2/app

    imports fyne.io/fyne/v2/internal/driver/common

Fyne does not yet support web assembly or delivering through a browser. You can watch our Tech Preview video from FyneConf last week to get an update on this work. https://youtu.be/t8gEzPujIVI
