I don't understand what the error is that you are reporting.
Can you share the compile error?
Or runtime crash?

hey man
i Explain error better
fyne.dialog is really OK with windows platform i tested
but it have error with android device when i test there
for example

package main

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

func main() {
	a := app.New()
	w := a.NewWindow("Hello")
	hello := widget.NewLabel("fyne")
	dialog.ShowInformation("s", "sd", w)
	w.SetContent(container.NewVBox(
		hello,
		widget.NewButton("Hi!", func() {
			hello.SetText("sd")
		}),
	))

	w.ShowAndRun()
}

shows error when lunch on android device show error "app repeatly closing"
but is ok on windows
and i meant if it's bug on fyne or must use another way to show dialog on android please let me know

Please share the error from adb logcat | grep Fyne - it will show why there is an error.
