Flutter FutureBuilder Widget
The FutureBuilder is a Widget that builds itself from the latest snapshot of interaction of a certain Future. If we create the future at the same time that we build the Future Builder, then the FutureBuilder's parent will be rebuilt everytime, the async task will eventually be restarted. It's a great what to wait for value before removing the Circular Procgress Indicator and show a different widget after. You can also handle errors coming from the Future if needed.
