Flutter/Dart - Open a view after a delay

To open a view after some delay you can use Future.delayed:

Future.delayed(const Duration(milliseconds: 500), () {
  setState(() {
    // Here you can write your code for open new view
  });
});

You can do it in 2 ways:

• Using Timer class.

  import 'dart:async';
  
  // Go to Page2 after 5s.
  Timer(Duration(seconds: 5), () {
    Navigator.push(context, MaterialPageRoute(builder: (_) => Screen2()));
  });
  

• Using Future.delayed class:

  // Go to Page2 after 5s.
  Future.delayed(Duration(seconds: 5), () {
    Navigator.push(context, MaterialPageRoute(builder: (_) => Screen2()));
  });
  

The benefit of using Timer over Future is its ability to cancel.
