When keyboard is shown, everything is pushed up and I get a error

Question

I have the following code:

    class _MyHomePageState extends State {
      @override
      Widget build(BuildContext context) {
        // This method is rerun every time setState is called, for instance as done
        // by the _incrementCounter method above.
        //
        // The Flutter framework has been optimized to make rerunning build methods
        // fast, so that you can just rebuild anything that needs updating rather
        // than having to individually change instances of widgets.
        return new Scaffold(
            body: new Column(
          children: [
            new Container(
              color: JBTheme.colorGreenBrand,
              height: 130.0,
              alignment: Alignment.bottomLeft,
              child: new Center(
                child: new Align(
                  alignment: Alignment.bottomCenter,
                  child: new Container(
                    color: JBTheme.colorOrange,
                    constraints: new BoxConstraints(maxWidth: 270.0),
                    child: new Row(
                      mainAxisAlignment: MainAxisAlignment.spaceEvenly,
                      children: [
                        new Column(

                            new Text("DKK")
                          ],
                        ),
                        new Expanded(child: new Image.asset("images/arrow.png")),
                        new Column(

                          mainAxisAlignment: MainAxisAlignment.center,
                          children: [
                            new Image.asset("flags/flag_us.png"),
                            new Container(
                              margin: const EdgeInsets.only(top: 4.0, bottom: 4.0),
                              child: new Text("USA"),
                            ),
                            new Text("USD")
                          ],
                        )
                      ],
                    ),
                  ),
                ),
              ),
            ),
            new Expanded(
                child: new Container(
              color: JBTheme.colorGreyMedium,
              child: new Column(
                children: [
                  new Expanded(child: new Container()),
                  new Padding(
                      padding: const EdgeInsets.only(bottom: 8.0),
                    child: new Card(
                      elevation: -8.0,
                      shape: RoundedRectangleBorder(
                        borderRadius: BorderRadius.circular(15.0),
                      ),
                      child: new Container(
                          width: 200.0,
                          height: 30.0,
                          color: JBTheme.colorWhite,
                          child: new Stack(
                            children: [
                              new TextField(
                                  textAlign: TextAlign.center
                              )
                            ],
                          )
                      ),
                    )
                  )
                ],
              ),
            )),
            new Container(
              height: 260.0,
              color: JBTheme.colorGreenMint,
            )
          ],
        ));
      }
    }

And it looks like this:

But when I click the TextField and the keyboard opens I get this:

I did not expect all of my layout to be moved up by the full keyboard height, I would like it to only move up enough so that the focused TextField is visible (and not to give a error). How can I fix this, and why is it happening?

Thank you

Answer 1

There are two solutions to this problem.

resizeToAvoidBottomPadding is now deprecated.

Below property of scaffold will work now. resizeToAvoidBottomInset set to false in scaffold widget.

1. Add resizeToAvoidBottomInset: false to your Scaffold

    Scaffold(
     resizeToAvoidBottomInset: false,
    body: ...)
   

2. Put your Scaffold body inside a scrollableView (like SingleChildScrollView or ListView)

    new Scaffold(
        body: SingleChildScrollView(child: //your existing body
    ...)
