iOS WebView + Keyboard Crash on Date Picker and Dropdown Selection (iOS 17+)

Current Behavior

Our Flutter app using flutter_inappwebview experiences crashes when interacting with date picker and dropdowns inside a WebView on iOS 17+ devices. The issue does not occur on iOS 17.4 Simulator but is consistently reproducible on real devices.

When selecting a date input field (nbcalendar JavaScript picker), the keyboard unexpectedly opens, causing excessive memory usage, and eventually, the app is killed by the OS due to low memory (EXC_BAD_ACCESS).

Steps to Reproduce:
Use flutter_inappwebview to load a web page containing a JavaScript-based date picker (nbcalendar).
On an iOS 17+ real device, tap on the date picker.
The keyboard opens unexpectedly , Memory usage increases, and after multiple interactions, the app is terminated by iOS due to excessive memory usage.

Expected Behavior

The WebView should not crash when interacting with date picker or dropdown and similar type of input fields which doesn't require keyboard.

                            (controller, url, androidIsReload) {
                          _callBackListener(controller, url.toString());
                        },

                          _sendEventToGetCountOfPageInForm();
                        },
                        gestureRecognizers: _gestureRecognizers,
                      )

Is this a known issue in iOS WebView (WKWebView) on iOS 17+?
Could this be caused by memory leaks within flutter_inappwebview when handling form inputs?
Any suggestions on workarounds or fixes for production apps?
