I have temperature sensor and I am getting the current temperature data from the API. What I want to do is updating the temperature value in the screen whenever it changes. To do that do I have to send request periodically or is it possible to subscribe to API ? Thanks in advance.
...ANSWER
Answered 2022-Mar-13 at 18:37That would depend on your API. If it can keep sending data when it changes, then sure you can use a StreamBuilder to rebuild on a changed state. Otherwise, you'll probably have to deal with a StreamBuilder with a Stream.periodic that sends the request every so many seconds (and still only rebuilds when the data has actually changed, of course).
