flutteralert

Start an Alert by opening page with Flutter web


Final Code which solved it

  @override
void initState() {
super.initState();

Future.delayed(Duration.zero, () {
  Alert(
    context: context,
    title: "JOJOJO",
    desc: "Flutter is more awesome with RFlutter Alert.",
  ).show();
});
}

I want to build an Flutter alert into my web app and when I open the website I want to pop it up immediately. The alert is build with the rflutter_alert package.

Does somebody have a solution to open this alert automatically?

Code of the Alert

_onBasicAlertPressed(context) {
Alert(
  context: context,
  title: "JOJOJO",
  desc: "Flutter is more awesome with RFlutter Alert.",
).show();
}

With the init State

Apparently it doesn't work when I just put it into the init state. However another function works with this way, the function that i want to activate for now only works by using onpressed in a button.

  @override
  void initState() {
    Alert(
  context: context,
  title: "JOJOJO",
  desc: "Flutter is more awesome with RFlutter Alert.",
).show();
super.initState();
callSendData();
}

Solution

  • Call your method in the initState()

    class StatefulWrapper extends StatefulWidget {
    
      @override
      _StatefulWrapperState createState() => _StatefulWrapperState();
    }
    
    class _StatefulWrapperState extends State<StatefulWrapper> {
    
     @override
      void initState() {
         Alert(
           context: context,
           title: "JOJOJO",
           desc: "Flutter is more awesome with RFlutter Alert.",
         ).show();
        super.initState();
      }
    
      @override
      Widget build(BuildContext context) {
        return Container();
      }
    }
    

    What is init state?
