The Body Mass Index Calculator.

Hello and welcome back. My latest Flutter and Dart project is my body mass index calculator or as some know it BMI. Body mass index is a somewhat out of vogue way of assessing if someone is of a healthy weight for their height and quite rightly so, many a professional Rugby player will have a BMI of 35 or above, particularly those forwards who are all muscle and muscle weighs more than fat. A safer option would be to assess %fat content but that is more difficult so I think that BMI calculation will be around for a bit longer yet so this app may well prove helpful. The calculation for body mass index is:-

BMI = weight in kilograms / (height in metres x height in metres) (substitute * for x if you prefer!).

My app also has a calculator for conversion of imperial weights (stones and pounds – British not US) to metric (kg), and another for imperial height or length (feet and inches) to metric (metres) which can them be used for the BMI calculator. I have included a calculate button for each calculation and a reset button to clear all of the boxes.

The Flutter Version of the BMI Calculator app.

It is the Flutter version of part of a previous Android app with several calculators within it. My intention is to ask those to whom I show all of these Flutter calculation apps which ones they would like to see as a suite and which would not be useful to them. I intend to have several sites; perhaps a paediatric suite and an adult based suite and target them at appropriate audiences. If you have any thoughts on the matter, please feel free to share them with me. Thank you.
