• Axel: Have you restarted the application?
• mohammad esmaili: I think restart and running project will help

Answer 1

You DataFromAPI has another MaterialApp without that parameter. I'd suggest to remove it there because now you have a MaterialApp inside a MaterialApp

• Aziz Lachkar: thank you i totally forgot about the material app insite the build widget

Answer 2

You have two material app in your code, remove this material app

 class MyApp extends StatelessWidget {
 @override
 Widget build(BuildContext context) {
 return MaterialApp(
 debugShowCheckedModeBanner:false,
 home: DataFromAPI(),
 );
 }
 }

and return

 DataFromAPI(),

Answer 3

Add debugShowCheckedModeBanner inside DataFromAPI MaterialApp widget.

 MaterialApp(
 debugShowCheckedModeBanner:false,
 home: new Scaffold( appBar: AppBar(
 title: Text(title_string),
 leading: IconButton(
 icon: Icon(Icons.arrow_back), onPressed: () { Navigator.push(
 context, MaterialPageRoute(builder: (context) => Home())); },
 ),
 ),
 .........

• Omi Shah: While your solution might work as intended but, it is not recommended to have two MaterialApp() widgets.
• Ravindra S. Patil: Yes ,we can remove MaterialApp widget inside MyApp class
