如何消除抖动对话框？ [英] How to dismiss flutter dialog?

问题描述

我是新手，我想在任务完成后关闭对话框。我尝试过：

I am new to flutter, I want to dismiss my dialog after the task completion. I've tried with:

Navigator.pop(context, true); 

但是我的屏幕变黑了，对话框仍然在那里。这是我的对话代码。

But my screen is getting black and dialog is still up there. here is my dialog code.

Dialog _dialog = new Dialog(
  child: new Row(
    mainAxisSize: MainAsixSize.min, 
    children: <Widget> [
    new CircularProgressIndicator(), 
    new Text("Loading")]),     

); 

推荐答案

https://docs.flutter.io/flutter/material/showDialog.html 说

此方法创建的对话框路由被推送到根导航器。如果应用程序具有多个Navigator对象，则可能有必要调用 Navigator.of（context，rootNavigator：true）.pop（result）关闭对话框，而不是 Navigator.pop（上下文，结果）。

The dialog route created by this method is pushed to the root navigator. If the application has multiple Navigator objects, it may be necessary to call Navigator.of(context, rootNavigator: true).pop(result) to close the dialog rather just Navigator.pop(context, result).

所以我假设其中之一这两个应该可以做您想要的。

so I'd assume one of these two should do what you want.
