Pass value when dialog closed

Question

I'm trying to create an app in Flutter.

When a particular button is pressed a Dialog shows up. In the dialog, the user can write to TextField. I want to use this text in the previous screen when the dialog is closed with pop().

Is there any way to do it?

Please add your code. So, we can tell you the changes. – Rohan Jariwala Aug 17 '22 at 14:14 — Rohan Jariwala, Aug 17 '22 at 14:14

try this:

showDialog(
  context: context,
  builder: (context) => Dialog(),
).then((result){
  // use the result here
});

and in dialog pop like this:

Navigator.pop(context, result);

You can await to get data from button. also You can pass data .pop(YourValue)

onPressed: () async {
  final data = await showDialog(
    context: context,
    builder: (context) {
      final TextEditingController controller =
          TextEditingController(); // this can be outside to get direct text from it
      return AlertDialog(
        content: TextField(
          controller: controller,
        ),
        actions: [
          TextButton(
              onPressed: () {
                Navigator.of(context).pop(controller.text);
              },
              child: Text("Close"))
        ],
      );
    },
  );
  if (data != null) {
    //your operation
  }
  print(data);
},
