A Flutter App calculate your body mass index (BMI).
My intention in creating this app was understating how the widgets work in Flutter and how can you structured the application. Also, learn more about Flutter.
The file Components have all the reusable widgets that I use on the screens.

Well, let´s start with the calculator_brain.dart, there I created a class CalculatorBrain that receives two parameters height and weight and with them, calc the BMI. The CalculatorBrain also has the methods 'getInterpretation and getResults' for return a message to the user and the result of the calc like 'Normal or Overweight'.
