Flutter InappWebView Pagkage question!

Currently I’m using webview_flutter:^2.1.1
On webview_flutter, I have applied tel and intent through navigationDelegate.

Writing code.

navigationDelegate: (NavigationRequest request) {
if (request.url.contains(“tel:”)) {
launch(request.url);
return NavigationDecision.prevent;
}else if (request.url.contains(“kakaolink:”)) {
launch(request.url);
return NavigationDecision.prevent;
} else {
return NavigationDecision.navigate;
}
},

Now, what I’m trying to do is that tranfering webview above to flutter_inappwebview: ^5.3.2 so that I can have more options.

I desire to get some advice how I should input webview in webview_flutter: ^2.1.1. above on flutter_inappwebview: ^5.3.2 .
I would really appreciate if you could give me some advice on this.
