How to prevent AlertDialog from not closing by clicking outside?

Question

I built an AlertDialog to display Loading while i'm authenticating the user and when it finishes i pop it.

Widget loadingDialog = new AlertDialog( content: new Row(   children: <Widget>[     new CircularProgressIndicator(),     Padding(       padding: const EdgeInsets.only(left: 8.0),       child: new Text("Loading..."),     ),   ], ),); 

But, if the user taps outside the Dialog it closes. So when the auth finishes, it will still pop something (i guess the scaffol), breaking the app. How can i make Dialog not closable?

Answer 1

There is a property inside showDialog called barrierDismissible. Setting this value to false will make your AlertDialog not closable by clicking outside.

showDialog(    ...    barrierDismissible: false,    ...
