如何在颤动键盘和焦点TextField之间增加空间？

如何解决如何在颤动键盘和焦点TextField之间增加空间？

我在滚动时遇到这个问题，当我聚焦文本字段时，红色容器覆盖了我要写的文本字段。如何控制滚动，以使文本字段显示在红色容器上方？

我想在keabord上方显示红色的Container，当用户在Textfield中书写时，我要激活nect按钮。

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key}) : super(key: key);

  @override
  _MyHomePageState createState() => new _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  FocusNode _focusNode = new FocusNode();

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
        appBar: new AppBar(
          title: new Text("Focus Example"),),body: Stack(
          children: [
            Row(
              mainAxisAlignment: MainAxisAlignment.center,crossAxisAlignment: CrossAxisAlignment.center,children: <Widget>[
                Expanded(
                    flex: 9,// 90% of space => (6/(6 + 4))
                    child: LayoutBuilder(
                      builder: (context,constraint) {
                        return SingleChildScrollView(
                          child: ConstrainedBox(
                            constraints:
                                BoxConstraints(minHeight: constraint.maxHeight),child: IntrinsicHeight(
                              child: Column(
                                children: <Widget>[
                                  new Container(
                                      height: 800.0,color: Colors.blue.shade200),new TextFormField(
                                    focusNode: _focusNode,decoration: new Inputdecoration(
                                      hintText: 'Focus me!',new Container(
                                      height: 800.0,],);
                      },)),Expanded(
                  flex: 1,// 10% of space
                  child: Container(
                    color: Colors.purple,alignment: Alignment.center,Align(
              alignment: Alignment.bottomCenter,child: Container(
                padding: EdgeInsets.only(left: 10.0,right: 10.0),height: 60,color: Colors.red,child: Row(
                  crossAxisAlignment: CrossAxisAlignment.center,mainAxisAlignment: MainAxisAlignment.spaceBetween,children: [
                    GestureDetector(
                        child: Text("Back",style:
                                TextStyle(color: Colors.white,fontSize: 18.0)),onTap: () {}),Container(
                      width: 40,height: 40,child: FlatButton(
                        textColor: Colors.white,disabledColor: Colors.grey,disabledTextColor: Colors.white70,padding: EdgeInsets.only(top: 0.0,bottom: 0.0),splashColor: Colors.white,onpressed: () {},child: Icon(
                          Icons.navigate_next,size: 35,)
                  ],)
          ],));
  }
}

解决方法

我可以给你个主意。尝试这样的事情，

body: Column(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,children: [
          Container(
            height: MediaQuery.of(context).size.height * 0.9 - 60,child: Row( ..... ),// Include SingleChildScrollView too
          ),Container(
                padding: EdgeInsets.only(left: 10.0,right: 10.0),height: 60,child: Row( ... )
          )
        ]

希望能解决您的问题。
