Go-flutter: It is recommended to add. The default position of the startup window is in the middle

Hey, can you add the window's default start position to the screen center in the flutter.WindowInitialLocation function?
I know that InitPluginGLFW is used to gain control over the glfw.Window

I'm not sure if initial location is something that we should force, or is something that maybe the systems' window manager should manage (keeping track of where it was last time). In any case, this could be something for a plugin, yes.

ok，Thank you

If you make such a plugin, please let us know, we could add it to the list of interesting plugins in go-flutter-desktop/plugins.

Hmm，no problem

This can be implemented without the use of a plugin.

This solution is better, thanks

Just in case anyone is looking for a quick way to use the above to have a specific initial window size but start the window center of the screen, you can use the following.

package main

// the file window-position-based-on-screen-size.go is used to set the initial
// location of the window regardless of screen resolution.
//
// The following example sets the window to the center of the screen

import (
    flutter "github.com/go-flutter-desktop/go-flutter"
    "github.com/go-gl/glfw/v3.3/glfw"
)

const windowHeight = 430
const windowWidth = 800

func init() {
    // Notice: Code in init() delays first frame!

    // Not best practice, you should let go-flutter make this call.
    err := glfw.Init()
    if err != nil {
        panic(err)
    }

    vidMoce := glfw.GetPrimaryMonitor().GetVideoMode()

    options = append(options,
        flutter.WindowInitialDimensions(
            windowWidth,
            windowHeight,
        ))
    options = append(options,
        flutter.WindowInitialLocation((vidMoce.Width/2)-(windowWidth/2), (vidMoce.Height/2)-(windowHeight/2)),
    )
}
