net:: ERR_SPDY_PROTOCOL_ERROR - Flutter webview app on android 6.0 Marshmallow

I created a flutter webview application and successfully tested on many emulator android api versions & a physical device running on Android 11. Lastly when I'm testing on my older android 6.0 device , I got an error message as mentioned below.

The webpage https://testsite.com could not be loaded because
 net:: ERR_SPDY_PROTOCOL_ERROR

If this error occurred to anybody / if anyone have solution for this, please help.

I found an article on internet said that this "ERR_SPDY_PROTOCOL_ERROR" can occur due to outdated web browser. So I tried to update the chrome browser on my phone. But it didn't solve my problem.

Finally I made it worked by updating the Android System WebView on google playstore. I think the error earlier happened is because of the very old Android System WebView.
