如何将数据发送到 Flutter 中的匿名 class？

Question

How do I send data back to a view when the view is anonymous (I am writing a library that takes a user from his present view to another, then return the users back to the initial view but also with a payload/data). In my code I go back to the anonymous previous view using:

Navigator.pop(context);

but how do I send data (string or object) along with it? or does flutter have a message dispatcher that is received by all views who listen for it?

Answer 1

Use

Navigator.pop(context, data);

The caller needs to listen it using

var data = await Navigator.push(...);
