android - 摆脱 android 虚拟键盘上的填充（颤振）

Question

当我在我的虚拟 android 设备上拉起虚拟键盘时，它看起来如下：

如您所见，键盘底部有大量黑色填充。我不知道如何摆脱这个。

我已经尝试过，它会在键盘未resizeToAvoidBottomPadding: false,显示时删除屏幕底部的填充，但在显示时无济于事。非常感谢任何输入！

代码：

Scaffold(
      backgroundColor:const Color(0xffFFF6E0),
      resizeToAvoidBottomPadding: false,
      child:GestureDetector(
          onTap: () {
            FocusScope.of(context).unfocus();
          },
          child:Container(
              child: Stack(
                  overflow: Overflow.clip,
                  children: <Widget>[
                        AnimatedPositioned(
                        duration: Duration(milliseconds: 400),
                        top:5,
                        bottom: (mode == 1)?MediaQuery.of(context).size.height*.18:MediaQuery.of(context).size.height,
                        left:5,
                        right:5,
                        child:Container(
                          decoration: BoxDecoration(

在返回之前的构建方法中添加这个

SystemChrome.setEnabledSystemUIOverlays([SystemUiOverlay.bottom]);
