ContentDialog class
Dialog controls are modal UI overlays that provide contextual app information. They block interactions with the app window until being explicitly dismissed. They often request some kind of action from the user.
To display a dialog, use the function showDialog
:
showDialog(
context: context,
builder: (context) {
return ContentDialog(
title: Text('Delete file permanently?'),
content: Text(
'If you delete this file, you won\'t be able to recover it. Do you want to delete it?',
),
actions: [
Button(
child: Text('Delete'),
autofocus: true,
onPressed: () {
// Delete file here
},
),
Button(
child: Text('Cancel'),
onPressed: () => Navigator.pop(context),
),
],
);
}
)
