dialog - 如何关闭 flutter 对话框？

Question

我是 Flutter 的新手，我想在任务完成后关闭我的对话框。我试过了:

Navigator.pop(context, true); 

但是我的屏幕变黑了，对话框还在上面。这是我的对话代码。

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

); 

Answer 1

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

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).

所以我假设这两个中的一个应该做你想做的。
