Question

我创建了一个聊天页面，其中包含标题，一个MessagesStream和一个Row，其中包含TextField和RaisedButton。我已经在GitHub和StackOverflow中检查了有关此问题的每个页面，但是找不到任何解决方案。当启动键盘时，该行不会上升，而是越过屏幕的底部，隐藏所有内容。

有人可以帮我解决这个问题吗？我真的尝试了一切。

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,

                        topRight: Radius.circular(30.0)),
                  ),
                  child: Column(

Answer 1

用Column包裹您SingleChildScrollView中的一个（可能是外面的）。问题在于，仅弹出键盘并不会突然告诉布局它需要能够滚动。您已经明确表示希望它能够滚动。

Answer 2

您可以使用Scaffold并将文本字段放置为bottomSheet

键盘隐藏TextField-Flutter
