Setup a Fyne project with Visual Studio Code

Make a directory for your project

mkdir fyne-example && cd fyne-example

Init with go mod

go mod init FyneExample

Get the dependencies

go get fyne.io/fyne/v2
go mod tidy

Paste code below into 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("Hi Mom!")

	hello := widget.NewLabel("Ya Mom :D ")
	w.SetContent(container.NewVBox(
		hello,
		widget.NewButton("Say Hi!", func() {
			hello.SetText("Welcome :)")
		}),
	))

	w.ShowAndRun()
}

Save and build binary, and run

# Build and manually execute binary file
go build
./FyneExample

# Run directly
go run main.go

Hope you enjoy it.

I plan release some tutorial by learning Fyne soon.

Something like a personal app for saving WIFI password for Coffee shop nearby my place.
