Error from this code.
void _showDialog(DialogRequest request) {
var isConfirmationDialog = request.cancelTitle != null;
showDialog(
context: context,
builder: (context) => AlertDialog(
title: Text(request.title),
content: Text(request.description),
actions: <Widget>[
isConfirmationDialog == !null?
FlatButton(
child: Text(request.cancelTitle),
onPressed: () {
_dialogService
.dialogComplete(DialogResponse(confirmed: false));
},
) : Container(),
FlatButton(
child: Text(request.buttonTitle),
onPressed: () {
_dialogService
.dialogComplete(DialogResponse(confirmed: true));
},
),
],
));
}
var isConfirmationDialog = request.cancelTitle != null; output of this is true or false .
and isConfirmationDialog == !null? here we are verifying not null instead of true or false
below code solved my problem
isConfirmationDialog ? FlatButton(
child: Text(request.cancelTitle),
onPressed: () {
_dialogService
.dialogComplete(DialogResponse(confirmed: false));
},
) : Container(),
This line looks crazy
isConfirmationDialog == !null?
I'm still using the same implementation in the stacked_services and it still works the same.
