How to Add a QR Code Scanner to a Flutter App for Android and iOS

Hi everyone!

Today I want to show you use the qr_code_scanner package to add a QR code scanner to your apps. There is a bit of configuration that goes into this so if you want to skip past this you can go to this timestamp:

0:00 - Package Installation
0:45 - Android Configuration
1:29 - iOS Configurations
1:51 - Show me the code!
11:01 - Demo time

Flutter is a cross platform app development framework that is growing rapidly in popularity, so if you're interested in mobile development it's time to start familiarising yourself!

You can find all my code for this flutter navigation tutorial on GitHub:

And the official documentation on flutter qr_code_scanner can be found here:

// ABOUT ME
My name is Chelsea and I started studying software engineering in 2010. I have been working commercially full time since 2014 and have been in various positions from graduate developer to tech lead to solution architect.
I'm a full stack developer with a lot of experience in C# and Javascript but my passion is for mobile development; specifically native iOS development and cross platform using React Native.

I always have many things on the go and am always trying out a new side hustle and failing at it; perhaps you can learn from my mistakes!

// PRODUCTS USED
I use the following products in the creation of my videos:

A reasonable quality and reasonably sturdy but cost effective microphone that can be used by both DSLR cameras, mobile phones and laptops

A kit lens but a decent quality lens for beginners getting used to a DSLR

This is the kit I started with it includes the lens linked above and is a great starter camera.

I love Apple devices... These are the ones I use for my channel content creation:

A good all round phone, good for Apple development and recording videos with enough high quality features but at a cheaper price point than the pro versions.

A nice portable computer for working from anywhere and perfect for iOS development

Really easy to use for graphic design if required for logos as part of my app development or editing the videos on the go.

For logo and icon design in Affinity Designer app for iPad

Adds keyboard and touchpad to iPad Air, making it easier to use for writing code/eBooks etc. on the go!
