键盘隐藏 TextField - Flutter

Question

我制作了一个包含 header、MessagesStream 和 Row 的聊天页面，其中包含 TextField 和 RaisedButton。我已经在 GitHub 和 Whosebug 中检查了关于此问题的每一页，但我无法找到任何解决方案。启动键盘时，该行不会上升，而是越过屏幕底部，隐藏所有内容。

谁能帮我解决这个问题？我真的什么都试过了。

这是我的 Scaffold:

  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: (){
        FocusScope.of(context).requestFocus(new FocusNode());
      },
      child: Scaffold(
        resizeToAvoidBottomInset: true,
        backgroundColor: Colors.lightGreenAccent,
        appBar: new AppBar(
          backgroundColor: Colors.lightGreenAccent,
          elevation: 0,
          leading: IconButton(
            icon: Icon(Icons.arrow_back_ios, color: Colors.white),
            onPressed: () => Navigator.of(context).pop(),
          ),
          centerTitle: true,
          title: Image(
            image: iconApp,
            height: 50,
            width: 50,
          ),
        ),
        body: SafeArea(
          child: Column(
            children: <Widget>[
              SizedBox(height: 10),
              Expanded(
                child: Container(
                  width: double.infinity,
                  decoration: BoxDecoration(
                      color: Colors.white,
                      borderRadius: BorderRadius.only(topLeft: Radius.circular(30.0),
                        topRight: Radius.circular(30.0)),
                  ),
                  child: Column(
                    mainAxisAlignment: MainAxisAlignment.start,

                        color: grayWhite,
                        elevation: 2,
                        child: Padding(

Answer 1

用 SingleChildScrollView 包裹你们 Column 中的任何一个（可能是外面的那个）。问题是简单地弹出键盘不会突然告诉布局它需要能够滚动。您已明确表示希望它能够滚动。
