Create a Search bar widgets in flutter used below code.

// Search bar in app bar flutter
class SearchAppBar extends StatefulWidget {
  @override
  _SearchAppBarState createState() => new _SearchAppBarState();
}

class _SearchAppBarState extends State<SearchAppBar> {
  Widget appBarTitle = new Text("AppBar Title");
  Icon actionIcon = new Icon(Icons.search);
  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
          centerTitle: true,
          title:appBarTitle,
          actions: <Widget>[
            new IconButton(icon: actionIcon,onPressed:(){
              setState(() {
                if ( this.actionIcon.icon == Icons.search){
                  this.actionIcon = new Icon(Icons.close);
                  this.appBarTitle = new TextField(
                    style: new TextStyle(
                      color: Colors.white,

                    ),
                    decoration: new InputDecoration(
                        prefixIcon: new Icon(Icons.search,color: Colors.white),
                        hintText: "Search...",
                        hintStyle: new TextStyle(color: Colors.white)
                    ),
                  );}
                else {
                  this.actionIcon = new Icon(Icons.search);
                  this.appBarTitle = new Text("AppBar Title");
                }


              });
            } ,),]
      ),
    );
  }

after that create a list of items and filter data add a new list and How to Create Searching with ListView in Flutter?

class ListSearchState extends State<ListSearch> {

  TextEditingController _textController = TextEditingController();

  static List<String> mainDataList = [
    "Apple",
    "Apricot",
    "Banana",
    "Blackberry",
    "Coconut",
    "Date",
    "Fig",
    "Gooseberry",

    "Orange",
    "Papaya",
    "Peach",
    "Pineapple",
    "Pomegranate",
    "Starfruit"
  ];

  // Copy Main List into New List.
  List<String> newDataList = List.from(mainDataList);

  onItemChanged(String value) {
    setState(() {
      newDataList = mainDataList
          .where((string) => string.toLowerCase().contains(value.toLowerCase()))
          .toList();
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        children: <Widget>[
          Padding(
            padding: const EdgeInsets.all(12.0),
            child: TextField(
              controller: _textController,
              decoration: InputDecoration(
                hintText: 'Search Here...',
              ),
              onChanged: onItemChanged,
            ),
          ),
          Expanded(
            child: ListView(
              padding: EdgeInsets.all(12.0),
              children: newDataList.map((data) {
                return ListTile(
                  title: Text(data),
                  onTap: ()=> print(data),);
              }).toList(),
            ),
          )
        ],
      ),
    );
  }
}
