Flutter 位于pdf（EasyWebView）顶部的窗口对话框（showDatePicker）的一部分不工作，也不响应

我使用两个插件：EasyWebView和showDatePicker。在EasyWebView中，我通过链接显示pdf。在某些情况下，我需要显示一个日期选择器对话框，使用showDatePicker，用户将在其中选择一个日期。问题是位于pdf（EasyWebView）顶部的窗口对话框（showDatePicker）部分不起作用。pdf侧面没有一个按钮不起作用。其余的按钮，不在表面上的pdf-工作

示例显示窗口对话框的A部分叠加在pdf上，不起作用，同时B部分工作正常

PDF（EasyWebView）小部件代码：

Expanded(
      flex: 2,
      child: new Container(
        padding: new EdgeInsets.only(left: 8.0, right: 8.0),
        child: Card(
          clipBehavior: Clip.antiAlias,
          child: SizedBox(
              height: 9000, // constrain height
              child: EasyWebView(
                src: widget.url, // API url
                isHtml: false,
                // Use Html syntax
                isMarkdown: false,
                // Use markdown syntax
                convertToWidgets: false,
                onLoaded: () {}, // Try to convert to flutter widgets
                // width: 100,
                // height: 100,
              )),
        ),
      ),
    );

    return Padding(
      padding: const EdgeInsets.only(top: 20.0),

              },

                ),
                child: TextFormField(

                    setState(() {

                        _endDate = endDatePicked;
                        _selectedDateText = getFormattedDateValue(_endDate);
                        endDataLog.comment = _endDate.toString();
                      }
                    });
                  },
                  validator: (val) => _selectedDateText == getFormattedDateValue(_endDate)

如何解决此问题？

解决方案是通过

showDataPicker（）的
TransitionBuilder
参数使用

例如：

final date = await showDatePicker(
    ...,
    builder: (ctx, child) => PointerInterceptor(child: child)
);
