Running for web from macos got stuck

Description

Browser got stuck when trying to run this script from a macOS. Also flet opens the system default browser and should open Chrome as Flutter does as default.

Only happens when trying to run on web. Run normally when using:

flet.app(target=main)

Code example to reproduce the issue:

import flet
from flet import IconButton, Page, Row, TextField, icons


def main(page: Page):
    page.title = 'Flet counter example'
    page.vertical_alignment = 'center'
    txt_number = TextField(value='0', text_align='right', width=100)

    def minus_click(e):
        txt_number.value = int(txt_number.value) - 1
        page.update()

    def plus_click(e):
        txt_number.value = int(txt_number.value) + 1
        page.update()

    page.add(
        Row(
            [
                IconButton(icons.REMOVE, on_click=minus_click),
                txt_number,
                IconButton(icons.ADD, on_click=plus_click),
            ],
            alignment='center',
        )
    )


flet.app(
    target=main,
    view=flet.WEB_BROWSER,
    web_renderer="html",
    route_url_strategy="path",
)

I am not a Flutter guy, but can you please explain why this is explicitly required?

And btw, what if Chrome is not installed?

First, as dev I would want to run Flutter web on my MacBook as I do normally with Flutter apps. So maybe is a hidden bug that could appear in other base system

Flutter documentation says that u need chrome for debugging. So if no Chrome you should not be able to debug for web.

What do you have on Network tab then, what resources are being loaded?
