Local Images Not Rendering in Android App Using Flet

[analytko]

Description

Hello,

I started development using Flet. I created an ft.image component pointing to my local image. When I run it using "flet run" or "flet run main.py," everything works correctly, and the image appears. However, when using "flet run --android" and opening the application using the app from the Play Store, my image is not rendered.

If I host the image (e.g., on GitHub) and use an HTTPS link as the src, the image appears.

Debugging the code, I noticed that when pointing to a path, for example, "/images/man.png," it adds a "rootfolder/main.py" prefix in the GET request.

Example: if I set ft.image(src="images/man.png"), the debug shows it as "GET rootfolder/main.pyimages/man.png" (as shown in the image).

I have already tried adding the assets folder to assets_dir and using Unix and Windows absolute paths. But it doesn't work, only with a hosted file.

Code example to reproduce the issue:

Main.py

import flet as ft
from router import get_router_view
import os 
def main(page: ft.Page):
    page.vertical_alignment = ft.MainAxisAlignment.CENTER
    page.horizontal_alignment = ft.CrossAxisAlignment.CENTER
    page.expand=True
    page.bgcolor=ft.colors.BLACK

    def route_changer(route):
        
        page.views.clear()
        
        page.views.append(get_router_view(page)[page.route])
        page.update()
        

    page.on_route_change=route_changer
    
    page.go("/login")

ft.app(target=main,view=ft.AppView.FLET_APP,assets_dir="assets")

Login

import flet as ft
import os
import logging
logging.basicConfig(level=logging.DEBUG)

class Login(ft.Container):
    def __init__(self, page: ft.Page):
        super().__init__()

        self.bgcolor=ft.colors.BLACK
        self.expand = True
        self.alignment=ft.alignment.center

    
    
        self.content = ft.Stack(
            expand=True,
            
            controls=[
                
                ft.Container(
                    expand=True,
                    bgcolor=ft.colors.BLACK,
                    content=ft.Image(src="images/man.png",expand=True)
                ),
                ft.ElevatedButton("just a test",bgcolor=ft.colors.WHITE)
               
             
            ]
        )

Hello. This issue still occurs on Flet 0.27.6

Local images show on Windows execution, but not in Android execution.

Code example for replicating

import flet as ft
import logging
logging.basicConfig(level=logging.DEBUG)
logging.getLogger("flet_core").setLevel(logging.INFO)


def main(page: ft.Page):
    counter = ft.Text("0", size=50, data=0)

    def increment_click(e):
        counter.data += 1
        counter.value = str(counter.data)
        counter.update()

    page.floating_action_button = ft.FloatingActionButton(
        icon=ft.Icons.ADD, on_click=increment_click
    )
    page.add(
        ft.SafeArea(
            # ft.Container(
            #     counter,
            #     alignment=ft.alignment.center,
            # ),
            ft.Image(
                src=f"/fgc.png",
                width=300,
                height=300,
            ),
            expand=True,
        )
    )


ft.app(main, assets_dir="assets")

Result

Image route is not correct, it parses out the '/' on image's src path f"/fgc.png"
