 Widget build(BuildContext context) {
    return new Scaffold(
        body:
      Column(
        children: <Widget>[
          Row(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: <Widget>[
              IconButton(icon: Icon(Icons.search), onPressed: () {
                setState(() {

                });
              }),
              new Flexible(
                child: new TextField(
                  onChanged: (String value) {
                    onchange(value);
                  },
                  maxLines: 1,
                  autocorrect: true,
//                  decoration: const InputDecoration(helperText: "Search"),
                  style: new TextStyle(fontSize: 10.0, color: Colors.black),
                ),
              ),
              _text != null ? IconButton(
                  icon: Icon(Icons.close), onPressed: (){
              }) : new Container(),

              IconButton(icon: Icon(Icons.bookmark_border), onPressed: () {}),
            ],
          ),
          new Expanded(
              child: FilstList(searchtext: _text,)
          ),


        ],
      ),
    );
  }
}

Answer 1

There are two solutions to this problem.

1. Add resizeToAvoidBottomPadding: false to your Scaffold

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

2. Put your FilstList(searchtext: _text,) inside a scrollableView (like SingleChildScrollView or ListView)

Answer 2

Use Scaffold property "resizeToAvoidBottomPadding: false" and "SingleChildScrollView" as parent of Scaffold body:

      home: Scaffold(
          resizeToAvoidBottomPadding: false,
          appBar: AppBar(
            title: Text("Registration Page"),
          ),
          body: SingleChildScrollView(
            child: RegisterUser(),
          )),

this will solve issue.

Answer 3

You should use resizeToAvoidBottomInset

Scaffold(
  resizeToAvoidBottomInset: false, // set it to false
  ... 
)

---

If you're having issues with overflow error, use SingleChildScrollView with it.

Scaffold(
  resizeToAvoidBottomInset: false, // set it to false
  body: SingleChildScrollView(child: YourBody()),
)
