如何将AlertDialog设置为不关闭并在颤动中单击外部 [英] How to set AlertDialog to don't close clicking outside in flutter

问题描述

我建立了一个AlertDialog，以在验证用户身份时显示正在加载"，并在完成时弹出它.

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..."),
    ),
  ],
),);

但是，如果用户在对话框外部点击，它将关闭.因此，当身份验证完成时，它仍会弹出一些内容(我猜是scaffol)，从而破坏了应用程序. 如何使Dialog无法关闭?

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?

推荐答案

showDialog中有一个名为barrierDismissible的属性.将此值设置为false将使您的AlertDialog无法通过单击外部关闭.

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,
   ...
