试试这个

我的解决方案是

使用isScrollControlled: true 添加填充 填充:EdgeInsets。只有(底:MediaQuery.of(上下文).viewInsets.bottom) 在SingleChildScrollView中包装布局

示例代码

Future<void> future = showModalBottomSheet(
  context: context,
  isDismissible: true,
  isScrollControlled: true,
  backgroundColor: Colors.white.withOpacity(0.2),
  builder: (context) => SingleChildScrollView(
    child: GestureDetector(
      child: Padding(
        padding: EdgeInsets.only(
          bottom: MediaQuery.of(context).viewInsets.bottom
        ),
        child: Container(
          width: MediaQuery.of(context).size.width,
          height: MediaQuery.of(context).size.height,
          child: Column(
            children: <Widget>[
              // add your widget here
            ],
          ),
        ),
      )
    ),
  )
);

把它添加到你的底页的最后一个小部件之后

Padding(padding: EdgeInsets.only(bottom:MediaQuery.of(context).viewInsets.bottom))

为了专注于键盘在BottomSheet - Wrap TextField在Padding Widget如下:

showModalBottomSheet(
              context: context,
              builder: (context) {
                return Container(
                  child: Padding(
                    padding: EdgeInsets.only(
                        bottom: MediaQuery.of(context).viewInsets.bottom),
                    child: TextField(
                      autofocus: true,
                    ),
                  ),
                );
              }); 

给那些不能解决问题的人尝试所有的答案。这些答案是正确的，但不太清楚。

当使用

MediaQuery.of(上下文).viewInsets.bottom)

make sure your context variable is using the one provided by bottom sheet builder property.

c builder:(* * * *) = > MediaQuery.of (c * * * *)

试试这个。

showModalBottomSheet(
        isScrollControlled: true,
        context: context,
        builder: (context) {
          return AnimatedPadding(
              padding: MediaQuery.of(context).viewInsets,
              duration: const Duration(milliseconds: 100),
              curve: Curves.decelerate,
              child: Container(
                  child: Wrap(
                children: [
                  TextField(
                    decoration: InputDecoration(labelText: "1"),
                  ),
                  TextField(
                    decoration: InputDecoration(labelText: "2"),
                  ),
                  TextField(
                    decoration: InputDecoration(labelText: "3"),
                  ),
                ],
              )));
        },
      )

如果你有全屏或固定大小的showModalBottomSheet，不要使用填充，这不会解决你的问题。使用边距代替填充，就像这样:

  showModalBottomSheet(
          context: context,
          builder: (context) {
            return Container(
                marign: EdgeInsets.only(
                    bottom: MediaQuery.of(context).viewInsets.bottom),
                child: TextField()
            );
          });
