How to solve this problem?

• Taking swift code from here and make it work on this Flutter plugin: https://github.com/cordova-rtc/cordova-plugin-iosrtc
• https://stackoverflow.com/questions/43916436/enable-camera-and-mic-access-in-wkwebview
• https://github.com/react-native-webrtc/react-native-webrtc

This is the unique solution I have found (this requires a lot of work).

After flutter upgrade, the project not building.

Break when target build version changed to 33 (Tiramisu on Android) Expected behavior: Build Complete Current behavior: Build Failed

Steps to reproduce

Nothing special to do. My project was able to build on targetSDK 32, but failed on targetSDK 33.

1. Create a simple project, set target SDK and compile SDK version to 33 in Android setting.
2. Depend on this library.

I am using this version flutter_inappwebview: ^3.3.0+3.

Below is my codes. The problem is that at some times it goes directly to this page only http://.../pay.php and stopped. I want direct to go this page and send the post value which will redirect to the payement gateway page. . Secondly at times this works perfectly but when I press the keyboard example to enter credit card details the page gets reload and I can never complete the form. How do I resolve this issue of keyboard and the proper redirection ? I have even put this line resizeToAvoidBottomInset: false,

webView.postUrl(
                      url: 'http://*.*.*.*/pay.php', 
                      postData: Uint8List.fromList(utf8.encode("detail=1&amount=200&order_id=A123&name=thiscustomer&email=[email protected]&phone=12345678"))

Description

Expected behavior: Website to load fast on 2nd or 3rd or above revisit.

Current behavior: Website doesn't load fast either 2nd, 3rd, or above revisit. I have test on my devices with good internet speed.

@pichillilorenzo Within CrossPlatform option, since the cacheEnabled is automatically set to True, I really want to know, whether it is working or not. And if it is working, then why is taking so much time. How to test caching part? Any other way to make site load faster without hampering or breaking the website.

@tneotia Did you know any other way or solution for this ?

Note- I have good and proper Internet speed.

@pichillilorenzo please fix it before next release of the plugin. Highly appreciated for the fix

This fixes an issue that I found while working on my app lrorpilla/jidoujisho#122 where I found that when a page is horizontally scrollable (typical when there is vertical text which can be found and used by CJK languages), the custom context menu does not show because it is rendered on the edge of the screen nowhere to be seen.

The solution is simply to add the offset so that the context menu is visible when horizontally scrolled.
