SearchData
void SearchData() {
info = new List.from(data);
for (int i = 0; i < info.length; i++) {
Widget routed = info[i]['route'];
Navigator.push(context, MaterialPageRoute(builder: (context) => routed));
// Widget test = Gorod();
// Navigator.push(context, MaterialPageRoute(builder: (context) => test));
}
}
an error comes out
[VERBOSE-2:ui_dart_state.cc(148)] Unhandled Exception: type 'String' is not a subtype of type 'Widget'
file Gorod();

}
}
class GorodState extends State<Gorod> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
iconTheme: IconThemeData (
color: Colors.white,

)
);
}
}
page code where I want to go
I want to take the path from the array and then substitute it and go to the page.

As can be seen from your error you are receiving string from your List.
There is no method to convert string to widget directly, so you have to manually check what you are getting from string by comparing and then you can create widget from it.
I hope Following minimal example will clear your idea.
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
var info = [
{
'id': 1,
'section_name': 'Name1',
'route': 'Gorod()',
'icon': 'Icons.location_city'
},
{
'id': '2',
'section_name': 'Name2',
'route': 'Gorod()',
'icon': 'Icons.chat'
}
];
List<Widget> searchData() {
List<Widget> _list = [];
for (int i = 0; i < info.length; i++) {
print(info[i]['route']);
if (info[i]['route'] == "Gorod()") {
_list.add(RaisedButton(
onPressed: () {
Navigator.push(
context, MaterialPageRoute(builder: (context) => Gorod()));
},
child: Text("text"),
));
}
}
return _list;
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: Container(
child: Column(
children: searchData(),
),
),
);
}
}
class Gorod extends StatefulWidget {
#override
State<StatefulWidget> createState() {
return GorodState();
}
}
class GorodState extends State<Gorod> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
iconTheme: IconThemeData(
color: Colors.white,
),
title: Text('Title Gorod', style: TextStyle(color: Colors.white)),
),
body: Container(
child: Text('Text fdsf fds fdsf'),
));
}
}
