How to Save Key Value Pairs Locally for a Flutter App using Shared Preferences Inc. Objects as Json

Hi everyone!

Today I want to show you how to get started with saving key value pairs locally in your Android and iOS cross platform app using Flutter's share preferences package which is similar to async storage of react native. I will show you how to save an integer to shared preferences and how to encode an object as JSON to save as a string in shared preferences, and then decode to get the object's values back out. This will be useful if you need to persist small amounts of data between different app sessions.

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 shared preferences tutorial on GitHub:

// 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!
