Flet Build APK Issue in New Release

[Muddassir-Farooq-official]

Duplicate Check

• I have searched the opened issues and there are no duplicates

Describe the bug

The bug is caused by a missing or incorrectly configured deep_linking attribute in the Flet project build process. Specifically, the build template you're using (flet-build-template) is trying to access a deep_linking configuration, but the attribute is either absent or improperly defined in the context of the project configuration.

The error occurs during the generation of the AndroidManifest.xml file, where deep linking permissions or configurations are required. The build system encounters an issue because it expects a deep_linking object in the context but can't find it, resulting in the following error:

'dict object' has no attribute 'deep_linking'

Code sample

Code

import flet as ft


def main(page: ft.Page):
    page.add(ft.SafeArea(ft.Text("Hello, Flet!")))


ft.app(main)

To reproduce

To reproduce the bug, follow these steps:

Prerequisites:
You need a system with latest pre release Flet installed.
Ensure you are using the Flet build template from flet-dev/flet-build-template.
You need to have Flutter, Android SDK, and Cookiecutter installed on your system.

What Android device do you have? Try running on Android simulator?

What Android device do you have? Try running on Android simulator?

I am using Techno Camon 19 Neo

[Muddassir-Farooq-official]

First app shows blank screen then showing unknown control webview but I didn't use webview in my code

[FeodorFitsner]

Honestly, it's impossible to tell whether your app is using WebView or not without looking at the sources, right? From "buildability" standpoint it looks like the app is running - Unknown control couldn't be displayed by its own. Maybe it's an old build, idk.
