![]() ",ĭouble height = double.parse(_heightController.text) / 100 ĭouble weight = double.parse(_weightController. It will help us in getting the value from the field. Now we will bind the input controller with the weight and height field. ![]() The above Code UI WILL BE ADDED HERE Step 3 Let's convert the skeleton to the flutter app. Let's build the basic scaffold firs then we will move into depth. These are the widget which I will be using in the application. Let's start the app by building the UI and it's easy but I will break into small part so that it will be more clear. Here is the video tutorial of building the BMI calculator, If you prefer watching video then you should watch this. This is again simply possible because all that is needed is the height and weight of a person.This was orignally published at nstack.in Get Started Another major reason the BMI is still used is that it has the ability to compare many groups of people and even entire countries by their BMI. Question: Body Mass Index Calculator App) The formulas for calculating the BMI are or Create a BMI calculator app that allows users to enter their weight. BMI Calculator: Easy and free app to calculate and monitor your body mass. Since then it has spread across the world and has thus already has amassed a great deal of data, not just people’s BMIs’ but in scholarly articles that use the simple BMI to link it to different health problems and diseases. UI/UX,Interaction Design,Adobe XD,Adobe Photoshop. The body mass index was developed in the 1800’s and has been widely used after World War 2 when it was used to link body weight with cardiovascular disease. Not only that but the fact that there are many different indices and formulas for these methods, it makes comparing them more difficult as well. Since each and every health index has its limitations, the BMI is still used because it is the broadest and by far simplest index to calculate: just weight divided by height squared.Įven though different health indices exist such as Body Fat Percentage that are more accurate in predicting whether a certain person has a healthy body weight or not, the problem with those is that they require slightly more effort in obtaining the appropriate measurements for each individual. These same limitations still arise in many different health indices and frankly will always have limitations, to different degrees, because for the simple reason that every person is different and thus no single index can comprise all people. Why is the BMI still used?ĭespite all the downfalls and limitations shown above that come with the body mass index, ironically those same limitations play a role in why it is still widely used. ![]() ![]() This means that for bodybuilders and very fit people, sometimes it’s better being "overweight" because to them the BMI is stating they are heavier than "normal" people, which is in fact the goal most bodybuilders want to obtain. One last thing to remember is that the "overweight", "underweight" readings shown in this BMI Calculator are relative to a pre-defined average "normal" body weight. Thus it is important to take all this into account when trying to understand your BMI reading and also speak with a doctor or nutritionist before undergoing any new fitness routine or diet. In reality, the "normal" body weights for people vary from age, gender, and population.Having high muscle mass can result in a higher BMI because muscle is more dense than fat and thus for the same height someone with a lot of muscle can weigh as much as someone with high body fat.Even though taller people tend to be thinner on average, their larger bone mass usually skews their BMI to slightly larger values.The "normal" proportion is used for all heights and weights even though not everyone has the same body type.Several issues arise with this method and those are listed below: It is used to screen for weight categories that may lead to health problems. With this BMI Calculator you can calculate and evaluate your Body Mass Index (BMI) based on the relevant information on body weight, height, age and sex. Basically the BMI assumes a "normal" body weight for men and women of average height and average fitness or activity level. BMI is a reliable indicator of body fatness for most people. It is important to note that the Body Mass Index is to be used as a general tool for determining a healthy body weight.
