How to reduce wasm size

[heejit]

package main

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

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

    w.SetContent(widget.NewButton(
        "Click me",
        func() { println("Hello!") },
    ))

    w.ShowAndRun()
}

above code producce 35MB wasm by running -> fyne package --target=web --release

We should consider making some optimisations to the WASM build as the standard ones don't work.
