How many people are in space right now?

'How many people are in space right now?' is an iOS and Android app, built with Flutter. In collaboration with, this app has similar functionality to Space Viewer. Additionally, the app's main screen shows the number of people, that are in space right now.

Flutter is a framework to build cross platform native apps in the Dart programming language. It has similar goals as React Native (fully native applications, not based on web views). I have documented my experience and made a comparisonhere.
