how to pass a variable value from one flutter page to another

Question

suppose, I have a file body1.dart where I created a variable "hello" which was initially empty!

String hello = "";

Now, in the same file, I have created a loop which will set and update the value of hello after every iteration!

Now the thing is whenever the value of "hello" get changed, I want to display that inside a Text Field which is in a different file body2.dart. I want to retrieve the real-time value at that exact moment! (Not the final outcome at the end of the loop)

Answer 1

Can you provide code snippet for this? So that we can best assist you.

Otherwise the best option would be to use a stream. You can have multiple dart classes subscribed to the same stream.

Streams provide an asynchronous sequence of data. Data sequences include user-generated events and data read from files. You can process a stream using either await for or listen() from the Stream API
