Flutter：AlertDialog内部堆栈

Question

我在堆栈内部有一个警报对话框，可以制作我的自定义对话框，如下所示：

源代码

onTap: () => showDialog(
                      context: context,
                      builder: (ctxDialog) => Scaffold(
                        backgroundColor: Colors.transparent,
                        body: Stack(
                          children: <Widget>[
                            AlertDialog(

                                height: sizes.height(context) / 7.5,
                                decoration: BoxDecoration(

                                backgroundColor: Theme.of(context).errorColor,
                                child: IconButton(
                                  icon: Icon(
                                    Icons.close,
                                    size: sizes.width(context) / 20,
                                  ),
                                  onPressed: () => print('close'),
                                ),
                              ),
                            )
                          ],
                        ),
                      ),
                    ),

一切都很好，但是问题是如果我将焦点放在文本字段上并且键盘显示出来，则关闭按钮的位置是固定的。如何使位置关闭按钮跟随警报对话框？

谢谢。

将您的AlertDialog小部件滑入SingleChildScrollView

SingleChildScrollView(
                padding: EdgeInsets.only(top: yourFocus.hasFocus ? 
                        MediaQuery.of(context).size.height / 2 - 250 // adjust values according to your need
                        : MediaQuery.of(context).size.height / 2 - 130),// adjust values according to your need
                child: AlertDialog(
                    title: Text("your Alert header text"),
                    content: TextField(
                             focusNode: yourFocus,
                             controller: yourTextController,
                             decoration: InputDecoration.collapsed(
                                        hintText: "your hint text."),
                             ),
                    actions: <Widget>[
                      FlatButton(
                          child: Text("Your button Title"),
                          onPressed: () {
                           yourFunction();
                          })
                    ]));
