Describe the bug

I attempted to run WebView on the Android platform, but found that it couldn't execute JavaScript. This issue doesn't exist on the web platform. Could you please tell me what might be the reason for this? flet==0.27.6 flet-webview==0.1.0 python==3.12 Android version 12

Code sample

Code

import flet as ft
from flet_webview import WebView

def main(page: ft.Page):
    wv = WebView(
        url="https://www.aixzzs.com/web/#/",
        enable_javascript=True,
        on_page_started=lambda _: print("Page started"),
        on_page_ended=lambda _: print("Page ended"),
        on_web_resource_error=lambda e: print("Page error:", e.data),
        expand=True,
    )
    page.add(wv)
      
ft.app(main)

To reproduce

1. Build the application as an APK(arm64-v8a). 2. Install the APK on an Android device or emulator.

Expected behavior

The expectation is that WebView on the Android platform can execute JavaScript and display interactive web pages.

@FeodorFitsner @ndonkoHenri Could you please help me with an answer?

@FeodorFitsner @ndonkoHenri - Guys we need help here. We're unable to run (or validate?) the JavaScript code in the WebViw. I'm trying to send JS code using a Text Field.

Hi team!

I found the fix for this. We need to edit the .dart file where the WebView controller is instantiated and add the Javascript mode to unrestricted.

Let me know if you need to know the specific file and code that you need to edit.

@ndonkoHenri @FeodorFitsner - I saw that you have made some changes in the Alpha release of the Webview. Let's also ensure that in the Dart file, the WebView controller is setting the Javascript mode to unrestricted.

Sure!
You can open a PR in the flet-webview repo with the modification and let's discuss from there.
If you can't, then just point the modifications to be done and we will have a look.
