Unable to open a new window inside web_view

I am currently implementing a payment gateway(paypal) for an app using the web view plugin. problem we are currently facing is that when the web_view first loads with the initial url passed, it displays little info and a button. when this button is clicked it should open a new window. why i try to do this with the flutter app we get this
`W/Web Console( 671): ppxo_button_pre_template_click at https://www.newWindowLink.com/api/checkout.js:260`

for the native app we are able to open a new window when the button is clicked and everything works as expected..
and we were able to achieve this using
`webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);`

i was able to go through the plugin code and found the above setting was not included.

Start by searching the plugin code for the Android WebView settings and compare it with the reported JavaScript window-opening setting. Confirm the behavior with the PayPal checkout flow: clicking the button should open the new window as it does in the native app.
