+# BMI Calculator 💪
+
+## Our Goal
+
+The objective of this tutorial is to look at how we can customise Flutter Widgets to achieve our own beautiful user interface designs. If you have a designer on board, no matter how unconventional their designs are, we can create them using Flutter. 
+
+
+## What you will create
+
+We’re going to make a Body Mass Index Calculator inspired by the beautiful designs made by [Ruben Vaalt](https://dribbble.com/shots/4585382-Simple-BMI-Calculator). It will be a multi screen app with simple functionality but full-on custom styling. 
+
+![Finished App](https://github.com/londonappbrewery/Images/blob/master/bmi-calc-demo.gif)
+
+## What you will learn
+
+- How to use Flutter themes to create coherent branding. 
+- How to create multi-page apps using Flutter Routes and Navigator.
+- How to extract and refactor Flutter Widgets with a click of the button. 
+- How to pass functions as parameters and fields.
+- How to use the GestureDetector Widget to detect more than just a tap.
+- How to use custom colour palettes by using hex codes.
+- How to customise Flutter Widgets to achieve a specific design style.
+- Understand Dart Enums and the Ternary Operator.
+- Learn about composition vs. inheritance and the Flutter way of creating custom UI.
+- Understand the difference between const and final in Dart and when to use each.

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
