A simple calculator in flutter

Hi there.

I published a simple calculator made in my spare time. It is written in flutter+dart and then uploaded to the store.

Is a simple calculator (no keystrokes supported yet) to test the flutter framework.

If you want to check out to use as an example, you can get the code in https://github.com/almejo/flutter-calculator and download from the store in https://snapcraft.io/flutter-calculator
