Search ListView In flutter

 Hello friends, today we will teach you how to search in list and listview.

Array List

List<Invoices> historyList = [];

if (response.statusCode == 200) {
  var responseData = json.decode(response.body);
  var orderHistory = responseData['invoices'];

  for (var coinJSON in orderHistory) {
    historyList.add(Invoices.fromJson(coinJSON));
    items.add(Invoices.fromJson(coinJSON));
  }

  print('---------------->${historyList.length}');

  print(responseData);

  setState(() {});
}

var items = <Invoices>[];

void filterSearchResults(String query) {
  List<Invoices> dummySearchList = <Invoices>[];
  dummySearchList.addAll(historyList);
  if (query.isNotEmpty) {
    List<Invoices> dummyListData = <Invoices>[];
    dummySearchList.forEach((item) {
      if (item.swiggyOrderId!.contains(query)) {
        dummyListData.add(item);
        print("yes");
      }
    });
    setState(() {
      items.clear();
      items.addAll(dummyListData);
    });
    return;
  } else {
    setState(() {
      items.clear();
      items.addAll(historyList);
    });
  }
}

Add method in Contoller

onChanged: (value) {
  filterSearchResults(value);
  setState(() {});
},
