How to dismiss an AlertDialog on a FlatButton click?
Navigator.pop() should do the trick. You can also use that to return the result of the dialog (if it presented the user with choices)
Navigator.of(context, rootNavigator: true).pop('dialog')worked with me.
Navigator.pop(_)worked for me, but the Flutter Team's gallery contains an example using:
Navigator.of(context, rootNavigator: true).pop()which also works, and I am tempted to follow their lead.
