How to pass data to a widget inside of another widget - flutter

Question

I was able to pass the data widget.value from the FirstPage to SecondPage. There's a widget called thirdWidget inside SecondPage.
How do I pass widget.value to thirdWidget?
class FirstPage extends StatefulWidget {
#override
State<StatefulWidget> createState() => FirstPageState();
}
class FirstPageState extends State< FirstPage > {
final myController = TextEditingController();
#override
void dispose() {
myController.dispose();
super.dispose();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('First Route'),
),
body: Column(
children: <Widget>[
TextField(
controller: myController,
decoration: new InputDecoration(labelText: "Enter a number"),
keyboardType: TextInputType.number,
),
RaisedButton(
child: Text("show text"),
onPressed: () {
return Navigator.push(
context,
MaterialPageRoute(
builder: (context) => ThirdRoute(
selectedDate: selectedDate,
value: myController.text,
)),
);
},
);
},
),
],
),
);
}
}
class SecondPage extends StatefulWidget {
final String value;
ThirdRoute({Key key, this.value})
: super(key: key);
#override
SecodpageState createState() => SecodpageState();
}
class SecodpageState extends State< SecondPage > {
#override
void initState() {
super.initState();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Calendar Page"),
),
body: Column(
children: <Widget>[
Text("${widget.value}"),
Row(
children: thirdWidget(),
),
Center(
child: RaisedButton(
onPressed: () {
Navigator.pop(context);
},
child: Text('Go back!'),
),
),
],
),
);
}
}
List<Widget> thirdWidget() {
return Text("${widget.value}”)
}

Answer 1

Use this in your SecondPage
Row(
children: thirdWidget(widget.value),
)
And update your thirdWidget like:
List<Widget> thirdWidget(var data) {
// data is widget.value
return [];
}

Answer 2

Just pass that info into the state class. Something like that:
class SecondPage extends StatefulWidget {
final String value;
ThirdRoute({Key key, this.value})
: super(key: key);
#override
SecodpageState createState() => SecodpageState(value);
}
class SecodpageState extends State< SecondPage > {
final String value;
SecodpageState(this.value);
#override
void initState() {
super.initState();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Calendar Page"),
),
body: Column(
children: <Widget>[
Text("${widget.value}"),
Row(
children: thirdWidget(),
),
Center(
child: RaisedButton(
onPressed: () {
Navigator.pop(context);
},
child: Text('Go back!'),
),
),
],
),
);
}
}
List<Widget> thirdWidget() {
return Text(value);
}
