   • List of String to List of StatefulWidget Flutter

     Top Answer

     Answered Jun 28, 2021 · 1 votes

     You cannot convert a String to a StatefulWidget.

     What you can do is use the string with NavigatorState to navigate to parts of the app.

     Global key for NavigatorState

     final GlobalKey<NavigatorState> navigatorKey = new GlobalKey<NavigatorState>();-

     main.dart

     class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Demo', debugShowCheckedModeBanner: false, theme: ThemeData( primarySwatch: Colors.blue, ), navigatorKey: navigatorKey, onGenerateRoute: (routeSettings) { switch (routeSettings.name) { //add more routes as needed case 'Home': return MaterialPageRoute(builder: (context) => Home()); default: return MaterialPageRoute(builder: (context) => Profile()); } }, home: MyHomePage(title: 'Flutter Demo Home Page'), ); }}

     Navigating to the page

     You can use this navigatorKey.currentState!.pushNamed(<Route Name>) to navigate to the page.

     Example : navigatorKey.currentState!.pushNamed('Home') This will navigate you to Home page.

     In your case, you can get the routes from an API and build a bottom Navigation bar and use the string to navigate to pages.

     Example:

     navigatorKey.currentState!.pushNamed(listStatefulWidget [index]);

   • List(of String()) contains String()

     Two arrays with the same contents are still not the same array. Something = Otherthing is false. That's why Contains doesn't work.

     You could instead use SequenceEqual

     to see whether any of the arrays in listStringArrays have the same contents as Otherthing.

     If listStringArrays.Any(Function(t) t.SequenceEqual(Otherthing)) Then

     You could use an immutable struct

     public struct Data{ public Data(int intValue, string strValue) { IntegerData = intValue; StringData = strValue; } public int IntegerData { get; private set; } public string StringData { get; private set; }}var list = new List<Data>();

     Or a KeyValuePair<int, string>

     using Data = System.Collections.Generic.KeyValuePair<int, string>...var list = new List<Data>();list.Add(new Data(12345, "56789"));-

     Depending on your needs, you have a few options here.

     If you don't need to do key/value lookups and want to stick with a List<>, you can make use of Tuple<int, string>

     :

     List<Tuple<int, string>> mylist = new List<Tuple<int, string>>();-// add an itemmylist.Add(new Tuple<int, string>(someInt, someString));-

     If you do want key/value lookups, you could move towards a Dictionary<int, string>

     :

     Dictionary<int, string> mydict = new Dictionary<int, string>();-// add an itemmydict.Add(someInt, someString);-

     With the new ValueTuple

     from C# 7 (VS 2017 and above), there is a new solution:

     List<(int,string)> mylist= new List<(int,string)>();-

     Which creates a list of ValueTuple type. If you're targeting .NET Framework 4.7+ or .NET/.NET Core, it's native, otherwise you have to get the ValueTuple package from nuget.

     It's a struct opposing to Tuple, which is a class. It also has the advantage over the Tuple class that you could create a named tuple, like this:

     var mylist = new List<(int myInt, string myString)>();-

     That way you can access like mylist[0].myInt and mylist[0].myString

   Nov 15, 2012 · List is just an interface, a definition of some generic list. You need to provide an implementation of this list interface. Two most common are: ArrayList - a list implemented over an array. List<String> supplierNames = new ArrayList<String>(); LinkedList - a list implemented like an interconnected chain of elements.

   Code sample

   List<String> supplierNames = Arrays.asList("sup1", "sup2", "sup3");

   System.out.println(supplierNames.get(1));
