Describe the bug

The example for locally hosted Lottie files produces this error Error loading Lottie: Unable to load asset:, the web-hosted one works fine.

It's not a malformed Lottie JSON, as I've tried with verified working Lottie files and get the same error.

Code sample

Code

import flet as ft
import flet_lottie as ftl


def main(page: ft.Page):
    page.add(
        ft.SafeArea(
            content=ft.Column(
                controls=[
                    ftl.Lottie(
                        src="https://raw.githubusercontent.com/xvrh/lottie-flutter/master/example/assets/Mobilo/A.json",
                        reverse=False,
                        animate=True,
                        error_content=ft.Placeholder(ft.Text("Error loading Lottie")),
                        on_error=lambda e: print(f"Error loading Lottie: {e.data}"),
                    ),
                    ftl.Lottie(
                        src="sample.json",
                        reverse=False,
                        animate=True,
                        enable_merge_paths=True,
                        enable_layers_opacity=True,
                        error_content=ft.Placeholder(ft.Text("Error loading Lottie")),
                        on_error=lambda e: print(f"Error loading Lottie: {e.data}"),

                    ),
                ],
            ),
        )
    )

Hi @Snak3Doc,
Did you have the local lottie file in the assets directory?
I tried to run your sample locally and everything works for me:

.
├── pyproject.toml
├── README.md
└── src
    ├── assets
    │   ├── sample.json
    │   ├── icon.png
    │   └── splash_android.png
    └── main.py

3 directories, 6 files

You can obtain this folder structure by creating your project with flet create command in the terminal.
Please try it and let me know :).

Maybe it's an issue with 0.82.2 then, cause I had them in the assets folder and used flet create

Can repro the issue on my Windows 11 VM, but code works normally on web and macOS.
