Calling an HTTP GET API from Flutter App with Future and FutureBuilder

Hi everyone!

Today I am going to show you how to make a GET request to an API from a Flutter app. I will also show you how to use FutureBuilder to show a progress indicator to the user while the API call is being made, and then display the api call data or error when the api call completes.

My code is available 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!

Thanks for this super simple tutorial. Please delete the default counter app and create just a basic scaffold from next time as the comments makes it difficult to follow along.

The video was exactly what I was looking for. Thanks a lot!!! 😃😃

Thanks for the example, very easy for people that are learning, I find a lot of this samples on the YouTube, but I wanted a basic one, the others are more complicated, and that's makes it harder to follow for a person that can make a simple mistake just by mistyping, or not writing a coma, or semicolon.
Same suggestion following Maruf Hassan.
Question, you created the integer for the "length", but is it necessary?, even thought it's not shown on the App. Also I made a little change to make the app to display another fact calling a function I created by pressing a FloatingActionButton I placed at the bottom center of the screen.
