A mobile application, developed with Flutter, the function is to calculate the body mass index, according to the height and weight of the person, in addition to having a little more information on the subject.
I think the most important part of the application is the lib and assets folder. Under assets, you will find the fonts and images used by the application. About the lib folder:
-
themes: Files containing the application theme.
-
constant: Texts I use in the
info_screen.dartfile. -
screen: The screen that the user can see.
-
widget: They are like components, the
screenfolder depends on them. -
route: The routes of the mobile application.
-
helper: Here is the logic of the application, like the formula.
-
class: Here are the texts and images that will be displayed based on the result.
I had a bit of difficulty with this project as I am very new to Flutter, so the communication between parent and child Widgets was confusing for me, I fixed it by passing functions as parameters. In other words, everything moves through the home_screen.dart file. Another problem was with the text themes, they gave me too many errors, but I managed to fix it, thanks to StackOverflow.
You can see the app running, just open the terminal and enter the following commands:
git clone https://github.com/YerikAH/calc-IMC
cd calc-IMC
flutter run
