I'm making a dialog containing a list of items, each of which includes an editable text field.

I'd like to save the contents of edited text fields to a SQLite database on dialog close.

How would I do that? There seems to be no such thing as an onClose listener in Flutter and once the dialog is closed, I won't be able to retrieve the text from text fields.

As You have not shared any code - so i share a minimal example of what you intend to do.

Data can be passed with the use of Navigator.

class DemoApp extends StatefulWidget 
 @override
 DemoAppState createState() 
 return new DemoAppState();
 


class DemoAppState extends State<DemoApp> 
 String val = 'Empty';

 TextEditingController cntrl = TextEditingController();

 @override
 void dispose() 
 cntrl.dispose();
 super.dispose();
 

 @override
 Widget build(BuildContext context) 
 return Scaffold(
 body: Container(
 child: Center(
 child: Column(
 mainAxisAlignment: MainAxisAlignment.center,
 children: <Widget>[
 Text('Value is -- $val'),
 RaisedButton(
 onPressed: () async 
 val = await showDialog(
 context: context,
 builder: (context) 
 cntrl.clear();
 return AlertDialog(
 title: Text('Enter Value'),
 content: TextField(
 controller: cntrl,
 ),
 actions: <Widget>[
 FlatButton(
 onPressed: () 
 Navigator.pop(context, cntrl.text);
 ,
 child: Text('Save')),
 ],
 );
 );
 setState(() );
 ,
 child: Text('Edit Value'),
 )
 ],
 ),
 )));

  Is there a way I can return that value without a button press? (Just closing the dialog by tapping the border around it)

  we actually need to pass value to - Navigator.pop - in the other case (Just closing the dialog by tapping the border around it) it's not happening. so no not directly. you can add - barrierDismissible: false, in showDialog so user do press button to close the dialog. @TinMan
