When can you really say that an app is reactive?

While I'm working trying to summarize the most important parts of this video, I noticed that it's mentioned that Flutter builds Reactive applications, when you can say that an application is reactive ?

So any interaction the user makes with the application makes the application a reactive application ? 💭

[nelsonic]

Indeed. it's just a fancy way of saying that the UI reacts to user interaction. But it's worth understanding flutter as "reactive" as in reactive programming: https://en.wikipedia.org/wiki/Reactive_programming Flutter is a declarative UI framework which just means you describe the whole layout in the code.

So in a few words I understood the purpose of each of the language types. 👍

Yeah, that's a good summary. 💡
