проблема появляется, когда я звоню любому из Flat Button, я уверен, что проблема связана с pop(), я уже пробовал эти две вещи,
, но без удачи до сих пор, поэтому Я был бы признателен за любую помощь, thx =)
showPickerDateRange(BuildContext context) {
Picker ps = new Picker(
hideHeader: true,
adapter: new DateTimePickerAdapter(type: PickerDateTimeType.kYM),
onConfirm: (Picker picker, List value) {
print((picker.adapter as DateTimePickerAdapter).value);
});
Picker pe = new Picker(
hideHeader: true,
adapter: new DateTimePickerAdapter(type: PickerDateTimeType.kYM),
onConfirm: (Picker picker, List value) {
print((picker.adapter as DateTimePickerAdapter).value);
});
List<Widget> actions = [
FlatButton(
onPressed: () {
Future.delayed(Duration.zero, () {
Navigator.of(context).pop();
});
},
child: new Text(PickerLocalizations.of(context).cancelText)),
FlatButton(
onPressed: () {
Future.delayed(Duration.zero, () {
Navigator.of(context).pop();
ps.onConfirm(ps, ps.selecteds);
pe.onConfirm(pe, pe.selecteds);
});
},
child: new Text(PickerLocalizations.of(context).confirmText))
];
showDialog(
context: context,
builder: (BuildContext context) {
return new AlertDialog(
title: Text("Select Date Range"),
actions: actions,
content: Container(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text("Begin:"),
ps.makePicker(),
Text("End:"),
pe.makePicker()
],
),
),
);
});
}
это вывод терминала
