animation
Adding a curve to animations in Flutter
Chaining transformation matrices
In a previous article, I showed how to do a slide-in animation. Each widget slid into place from below (or the side) using a Transform Widget in an AnimatedBuilder.
But what if you want to add a curve to the slide?
And that is what chaining transformation matrices is for.
If you have knowledge of transformation matrices already, you don’t need this article. Go read a good book with a cup of your beverage of choice next to you :)
Enjoy. [Created using Dall-E]
If not, you’ve come to the right place.
Slide-in animation in a column in Flutter
As we all know, a functional app is great…but it’s not enough. It needs to be easy to use; it needs to be intuitive; and it needs to be cool.
So it’s not enough to show the data in a column. It would be so much cooler to have it slide in:
But… how to do that?

Animating Widgets in Flutter Grids: Part III - Flow
Sometimes, you need to transition between two different kinds of grids in your app. For example, you have a grid of images and the user wants to see only the user’s favorites. Some widgets may stay the same, while others change. How can you animate this transition, making existing widgets smoothly move and resize within the grid?
In the first article of the series, we explored transitioning between different pages using the Hero widget. However, Hero widget is only triggered by push and pop actions, so it isn’t suitable using another method e.g. a TabBar.
In the second article, we transitioned between tabs using AnimatedPositioned widget. It is more complex to use, but works with TabBars and allows more fine-tuning in the animation parameters.
In this article, we will explore the Flow widget:

Private-Convert: Free private online tool to convert files
It sounds like an oxymoron — if it’s online, it obviously can’t be private, right?
Wrong.
This site does everything on the client’s side, which means everything is done locally on your computer. Your files are not uploaded to a server at any time, they never leave your computer at all. This makes the conversion:
- Private
- Fast
That fast.

Write, view and share files in Flutter
Many apps need to save files that the user can afterwards view such as log files, data files, etc. I used to create the files and save them in Downloads or Documents. However, as Android becomes more security and privacy conscious, Android is using storage scoping, and saving csv files to Downloads has become difficult. Each app has its own folder for app files, where it can save whatever it wants without additional permissions needed. However, this is typically not accessible to the user. The solution is to have from within the app a page that allows the user to view the app files, select them, and share them. But how to do this in Flutter?

Space clouds
My original plan was to create a simulation of ink spreading in water (spoiler: I didn’t succeed). I figured that I was looking at diffusion, so I used the following model: start with 50 points at one position (a Diffusing Drop). Each of these points now execute a random walk. What would it look like? You can see the results below and play with the parameters.

How to convert Medium to Markdown using VSCode keybindings
I have my own website (this site!), using GitHub and Jekyll. Originally, I just linked to my Medium articles from my website, but this is not good practice — no one wants to enter a website and see a bunch of links.
As Medium does not yet support my country in the Partner program, I don’t lose money by posting the same article on my site. But copying manually is tedious and boring.
So here is how to copy the article into Markdown in VSCode, using some handy shortcuts.

Whether you are a beginner or an experienced Arduino user, this tutorial will provide you with the knowledge you need to start using hardware triggers in your projects.

Slide-in animation in a column in Flutter
As we all know, a functional app is great…but it’s not enough. It needs to be easy to use; it needs to be intuitive; and it needs to be cool.
So it’s not enough to show the data in a column. It would be so much cooler to have it slide in:
But… how to do that?

Adding a curve to animations in Flutter
Chaining transformation matrices
In a previous article, I showed how to do a slide-in animation. Each widget slid into place from below (or the side) using a Transform Widget in an AnimatedBuilder.
But what if you want to add a curve to the slide?
And that is what chaining transformation matrices is for.
If you have knowledge of transformation matrices already, you don’t need this article. Go read a good book with a cup of your beverage of choice next to you :)
Enjoy. [Created using Dall-E]

How to convert Medium to Markdown using VSCode keybindings
I have my own website (this site!), using GitHub and Jekyll. Originally, I just linked to my Medium articles from my website, but this is not good practice — no one wants to enter a website and see a bunch of links.
As Medium does not yet support my country in the Partner program, I don’t lose money by posting the same article on my site. But copying manually is tedious and boring.
So here is how to copy the article into Markdown in VSCode, using some handy shortcuts.

Private-Convert: Free private online tool to convert files
It sounds like an oxymoron — if it’s online, it obviously can’t be private, right?
Wrong.
This site does everything on the client’s side, which means everything is done locally on your computer. Your files are not uploaded to a server at any time, they never leave your computer at all. This makes the conversion:
- Private
- Fast
That fast.

How to test GPS in Flutter using Android emulator
In the app I’m currently developing, I need to save the users’ current location. In addition, I need to check if the user is driving.
The excellent geolocator plugin is easy to use and has extensive documentation and examples. Creating a simple class that returns the current location and checks the current speed is trivial.
