Can not make pinch gesture in Android

[ber6789]

Flutter version: 1.12.13+hotfix.5
Plugin version: 2.1.0+1 ( now the latest on github)

Hi ,friend, glad to consult you again 🙂 , recently I have another problem of this plugin (only occured in Android ) , which also made me headache , here are the steps

===============================================================

1. start a InAppWebview page and load this url ( this is baidu map)
   https://map.baidu.com/mobile/webapp/index/index/foo=bar/vt=map

2. when loads complete , you 'll find that if you wanna pinch on the map , it won't work
   (even if I set supportZoom true ，still not work)

3. in the older version of this plugin ( previously , I choosed 1.2.1 ), it would work very fine

===============================================================

The followings are the screenshot and the option part of my codes like:

    ```
        initialOptions:InAppWebViewWidgetOptions(
                   
                    

                     crossPlatform: InAppWebViewOptions(
                        //debuggingEnabled: true,
                        //verticalScrollBarEnabled:false,
                        //horizontalScrollBarEnabled:false,
                        userAgent: Platform.isIOS?

                        transparentBackground:true,
                        preferredContentMode: InAppWebViewUserPreferredContentMode.MOBILE,
                        
                        


                    ),
                    android: AndroidInAppWebViewOptions(

                        textZoom: 100,
                        useWideViewPort: false,
                        supportZoom: true,
                        builtInZoomControls: true,
                        displayZoomControls: true,
                    ),
                    ios: IOSInAppWebViewOptions(

                        //suppressesIncrementalRendering: true
                        //enableViewportScale:true,
                    )
                 ),

So is there something to do with your updates , so that PINCH is forbidden for some reasons in Android ?

hope you can help me , best gratitude for you, and wish you a merry Christmas ！😀

We currently have the same problem as described above. We have tried in many ways and the problem persists.

It only seems to be working when you set mode to DESKTOP

Here is the sample code

Expanded(
child: InAppWebView(
initialUrl: "https://www.flutter.dev",

                initialHeaders: {},
                initialOptions: InAppWebViewWidgetOptions(  
                  crossPlatform: InAppWebViewOptions(
                      debuggingEnabled: true,
                      disableVerticalScroll: true,
                      preferredContentMode: InAppWebViewUserPreferredContentMode.DESKTOP
                    
                  ),
                  android: AndroidInAppWebViewOptions(
                    builtInZoomControls: true,
                    //displayZoomControls: true,
                    supportZoom: true
                  )
                
                ),
                onWebViewCreated: (InAppWebViewController controller) {
                  webView = controller;
                  
                  controller.addJavaScriptHandler(handlerName: "seataddl", callback: (args){
                    print(args);
                    
                    return;
                  });
                },
                onLoadStart: (InAppWebViewController controller, String url) {
                  setState(() {
                    this.url = url;
                  });
                },
                onLoadStop: (InAppWebViewController controller, String url) async {
                  setState(() {
                    this.url = url;
                  });
                },
                onProgressChanged: (InAppWebViewController controller, int progress) {
                  setState(() {
                    this.progress = progress / 100;
                  });
                },
              ),
          ),
