Flutter Widgets Explorer: An app to learn and showcase your Flutter Widgets on the mobile and web.

The Web version of the Flutter Widgets Explorer finally released to production at fluwix.com.

You see a word “finally” in the sentence above as the efforts required to web-enabled a Flutter mobile apps is greatly underestimated by me. I initially thought that I just need to make the layout of the app responsive, then it should run on the web automatically. The current stage of Flutter web support prove me wrong.

I wouldn’t like to bore you with…

Deploy scikit-learn, spaCy and Keras models to AWS

I just completed the Udemy course with the same title of the blog post.

The course cover three machine learning examples using different library:

  1. scikit-learn: Using regression model from scikit-learn trained on California housing dataset for house price prediction.
  2. spacy: Using a small English model from spaCy NLP framework for named entity recognition.
  3. keras: Using ResNet50 computer vision deep learning model from Keras framework to create for image recognition.

Let’s me tell you the following value-added changes of my code from the original source code from the course:

  • The examples are using Python 3.8 instead of…

I wrote this article to inform Flutter developers for a lesser known feature of Flutter: Multi-modules support in a Flutter project. Thanks for inspiration from an article A Flutter BLoC + Clean Architecture journey to release the #1st Idean Flutter app published on Medium.com. It mentioned about “Dart modules”, I not sure whether we are referring to the same thing here.

After gone through the article above, I perform a google search for Flutter module and I found many articles and videos on how to create modular Flutter project, or how to structure Flutter…


The Neumorphism Design showcase the example of the flutter_neumorphic package created by Idean.com. There are 6 categories of showcase such as Neumorphic Playground, Text Playground, Samples, Widgets, Tips and Accessibility.

You can see the following showcase live powered by Fluwix.com:-


I’m glad to inform you that Flutter Widgets Explorer is rebranded to Fluwix. Start from now the mobile apps and the web app under one brand name.


Thanks for sharing a great article. I published a similar article, but I'm using flutter modules instead of melos at https://limcheekin.medium.com/flutter-multi-modules-support-57e9acd21c7a


The Percent Indicator display animated progress widgets based on percentage, can be Circular or Linear, you can also customize it to your needs.. It was created by Diego Velásquez.

Let’s say you’re a ML practitioner working in start up, small company or any company that had limited budget and you would like to explore the use of MLflow to manage your team’s machine learning life cycle, but you don’t want to take the hassle of setup your own instance of MLflow. Then, the good new is “You can have your own MLflow tracking server and MLflow UI running on the cloud for $0.01 only”, that’s sound unbelievable, right?

I found the following great deal from AWS Marketplace:

These 4 stages also being structured in 4 parts of the book

These four stages is defined by Emmanuel Ameisen in his recent book Building Machine Learning Powered Applications. As I think it is an important piece, I created a process diagram above and note down few important points for each stage. You can considered this is a study note.

1. Identifying the Right ML Approach

The best approach for a given problem (product goal) will depends on success criteria, data availability, task complexity and model choice.

2. Building an Initial Prototype

Start by building an end-to-end prototype before working on a model which aim to tackle the product goal with no ML involved and will allow you to…

Start from now, you can treat Flutter Widgets Explorer as a platform to showcase your widget with README, codes and licensing information. The Flutter Widgets Explorer supports Android devices at the moment and will support Web in a week or two.

That’s made possible by the Showcase View widget, let’s me show you how it looks:
