Flutter textfield打开键盘颤振

从中可以看出，我对下面的文本字段有一个约束问题。一旦按下，键盘就会打开，但它会重叠并破坏整个视图。我如何解决和管理这个问题

问题可能在于qrima的维度设置不当

他们建议我在脚手架上管理所有东西，然后设置resizeToAvoidBottomInset:false，但我没有注意到任何改进

  @override
  Widget build(BuildContext context) {
    Size size = MediaQuery.of(context).size;
    _buttonHeight = size.height * .05;

    double splitPoint = size.height / 7;

    return Scaffold(
        resizeToAvoidBottomInset: false,
        body: Stack(
            children: [FutureBuilder<UserData>(
          future: contentManager.getUserData(),
          builder: (context, AsyncSnapshot<UserData> snapUserData) {
            if (snapUserData.hasError)
              return Container(
                child: Center(
                  child: Text("There was some error"),
                ),
              );
            if (snapUserData.connectionState != ConnectionState.done)
              return Container(
                child: Center(
                  child: CircularProgressIndicator(valueColor: new AlwaysStoppedAnimation<Color>(appColors.yellow)),
                ),
              );
            return Stack(
              alignment: AlignmentDirectional.center,
              children: [
                // SFONDO
                Positioned(
                  bottom: 0,
                  child: Container(
                    height: size.height,
                    width: size.width,
                    color: appColors.primaryColor,
                  ),
                ),
                // TITOLO
                Positioned(
                  top: size.height * .05,
                  child: Text(
                    localization.showQR,
                    style: Theme.of(context).primaryTextTheme.headline5.copyWith(
                      color: appColors.green,
                      fontWeight: FontWeight.bold,
                    ),
                  ),
                ),
                Positioned(
                  top: size.height * .10,
                  width: size.width * .8,

                      fontWeight: FontWeight.bold,
                    ),
                  ),
                ),

                        borderSide: BorderSide(color: Colors.white),

    ]),

  }

使用SingleChildScrollView小部件包装整个内容，如下所示：

Scaffold(
  body: SingleChildScrollView( 
    child: Stack( 

    )
  )
)
