TL;DR: I built a tool that lets you inspect app-state in real-time and allows you to do even more in the future. Visit www.detective.dev for instructions on how to use it.
This is a widget builder for Flutter. At first, it might look like just another layout builder, but this is going to be so much more.

These are the features I feel are the core of the whole project.
Keep in mind, most of these features are not implemented yet.
There is not going to be any copy paste. You can work with the drag and drop interface while simultaneously modifying the code.
Have you ever thought about how cool it would be if you could just make this quick change in your app without opening your laptop? Or you simply thought about the idea of writing Flutter apps on your phone.
I did some experimenting and I might have something for you!
If you want to try it out, head over to this Github repository which has a detailed setup guide.
This article will take a look at the hows and whys.
It’s probably simpler than you thought.
The compilation is still being done by a PC.
What is happening is that…
At its core, Flutter is a standalone, binary executable; making it a game-changer not only on mobile, but on desktop as well.
Writing once and deploying natively on Android, iOS, Windows, Mac and Linux and additionally sharing all the business logic to the web (using AngularDart) is a big deal.
Let’s explore this idea!
But before taking a look at actual native desktop apps, let’s see what running Flutter on desktop can do for people developing for mobile.
The first thing that happens before anything productive can be done is starting the android emulator and running Gradle.
In the following…
It has been a long time since I last posted here on medium. Interestingly my follower count kept growing — so thanks for that! :)
When I started posting on Medium back in February. I didn’t really know what I was doing (I still don’t).
My first post “Flutter: How I built a simple app in under an hour from scratch. And how you can do it too.” got featured on AndroidProDev and got pretty big.
I wrote it because I saw a YouTube video about Flutter and tried it out. I was so amazed, that I thought “Why not…
Villains allow you to add page transition like the one above with just a few lines of code.
One of the most awesome parts of flutter is having such a nice and clean API for everything. I just love the way you can use Heroes. Two simple lines of code, and it just works. …
Ever wondered how Flutter takes those widgets and actually converts them to pixels on the screen? No?
Understanding how an underlying technology works makes the difference between a good developer and a great one.
You can create custom layouts and special effects more easily when you know what works and what doesn’t; and knowing this will save you a few long nights at the keyboard.
The goal of this post is to introduce you to the world beyond the surface of flutter. We will take a look at different aspects of flutter and understand how it actually works.
Usually your entry point to the app looks like this:
If you want to change the theme of your app at compile time you can modify
ThemeData. There is an attribute called
Brightness which changes a bunch of colors from light to dark if set to
We want it to dynamically change that variable during runtime. We therefore introduce state to the top level widget.
Now, we have to access this state. Either by passing down a callback, writing a custom
InheritedWidget or using the
BuildContext to walk up the tree.
Passing down a callback is…
Taking the bookshelf app from demo to a real app.
“Collecting books as you read them, virtually”
It isn’t rare that people don’t own the physical book but instead read them on an e-reader, listen to them as an audio books or simply lend them a from friend. The books have been read but the shelf stays empty. There is no sense of accomplishment and more importantly no collection of books to show your grandchildren.
There are two aspects to the app: collecting books and discovering new books.
In this post I’m am going to discuss a good way to store/ cache/ and load data. Most of today’s apps rely on a server to display information. In combination with a cache, a database and error handling, this can become pretty messy. Luckily there is a design pattern which makes accessing data very convenient and easy.
