Thoughts on the cross-domain problem of images

[lrbmike]

I studied streamlit before, and when I wanted to migrate the function to flet, I found that the image had a cross-domain problem, and the same image address would not appear cross-domain in streamlit, but it would appear in flet, which made me very confused.

streamlit code:

flet error:

As far as I know, streamlit seems to handle cross-domain images through internal servers, so does flet have a similar processing mechanism? If not, can you refer to this method?

And now I'm using the FLASK framework to open a proxy server inside the flet to handle the cross-domain problem of images，the code is as follows

# proxy server
from flask import Flask, request, send_file
import threading
import requests
from io import BytesIO

# create Flask app
app = Flask(__name__)


# proxy router
@app.route('/proxy')
def proxy():
    url = request.args.get('url')
    response = requests.get(url)
    return send_file(BytesIO(response.content), mimetype='image/jpeg')


# run Flask thread
def run_flask():
    app.run(port=5000)


flask_thread = threading.Thread(target=run_flask)
flask_thread.daemon = True
flask_thread.start()

image proxy

image_url = "http://localhost:5000/proxy?url=" + image_url

Try using the html web renderer:

ft.app(main, web_renderer=ft.WebRenderer.HTML)

If I run as a web app (flet run --web main.py), it work. But if not, it doesn't.
So if I want to run as a desktop app, Is there any way to deal with it ?
