Flutter showDialog(context) in initState method

Question

I'm trying to use the showDialog(context, builder) to display a greeting message when the user navigates to a certain page.

I tried this by calling the showDialog in the initState method of a stateful widget on that page. While it does work, it appears I don't have access to the actual context.

Is there a way in Flutter to access the context in the initState() method?

If not, is there another way to achieve this behaviour in a better way?

@override
void initState() {
  super.initState();
  new Future.delayed(Duration.zero, () {
    showDialog(context: context, 
    builder: (BuildContext context) {
      return new Container(child: new Text('foo'));
    });
  });
}

For newcomers, you have access to context in initState as others said. The only problem here in initState build function is not executed yet. So this context is kind of empty.

To solve this, you can use SchedulerBinding:

SchedulerBinding.instance.addPostFrameCallback((_) => doSomethingNextFrame(context));

addPostFrameCallback: Schedule a callback for the end of this frame.

Future.delayed(Duration.zero) will also work. But I think SchedulerBinding looks cleaner.
