Understanding dependencies: and dev_dependencies: in Flutter

If you develop in Flutter, you might remember seeing the dependencies: and dev_dependencies: sections in the pubspec.yaml file. Here is how they work.

Courses in June 2019

Learn Cross Platform Mobile Apps Development

There are a couple of frameworks available for developing cross-platform mobile apps - apps that run on iOS and Android with a single code base. In the month of June, we have the following courses available:

• MOB105 Cross Platform Mobile Apps Development using React Native and ECMAScript 
• MOB107 Cross Platform Mobile Apps Development using Flutter 

To make it easier to test your applications on the Android platform (for iOS you can use the Simulator), both courses come with an AndroidOne device. At the end of the training, you will be able to bring the device back home.

Programming Internet of Things (IoT)

In the month of June we will run three different IoT courses:

• IOT104 Programming Internet of Things (IoT) using Arduino 
• IOT107 Programming the micro:bit 
• IOT101 Programming Internet of Things (IoT) using Raspberry 

We have added new modules and lab exercises to all these courses. In particular, we are covering:

• Fingerprint scanning in IOT101 and IOT104
• Using Blynk and ThingSpeak in IOT101
• Touchscreen in IOT101
• Controlling relays using ESP-01 in IOT104

Blockchain and Smart Contract Programming

Blockchain technology is in high demand in the year 2019. Talk about Blockchain and people start to associate it with Bitcoin. But Blockchain is more than just cryptocurrencies. In particular, a programmable Blockchain like Ethereum is more useful. We have a course in June that shows you how to program the Ethereum blockchain and create your smart contract. Using Smart contract, you can build applications that:

• require decentralised trust (such as OpenCerts)
• automate the transfer of crypto-assets automatically
• automate transactions and eliminate costly third party agents

The Blockchain course in June:

• IOT301 Fundamentals of Blockchain and Smart Contracts Programming using the Ethereum Network 

Programming Courses

The recent Stackoverflow Developer Survey 2019 reveals that Python has “edged out Java” and is the second most loved language. Stack Overflow refers to Python as the “fastest-growing major programming language”.

Python is used for many different tasks - automation, desktop and web, scientific, as well as artificial intelligence. If you have not started programming Python, now is a good time!

• IOT201 Applied Python Programming 

Node.js is an open source, cross-platform runtime environment for creating Web apps and Web services. Node.js apps are written using JavaScript, and it provides an event-driven architecture and a non-blocking I/O API that enhances an application’s throughput and scalability.

In our Node.js course, you will learn how to:

• Write REST APIs
• Use nvm to install different versions of Node.js
• Use npm to manage your packages
• Use npm to publish your own modules and libraries to the Node.js repository 

Here is the run in June:

• WEB106 Programming Server Apps using Node.js

Introduction to Coding using the micro:bit (for kids 7 to 13)

Want to get your child started in programming? In this one day code camp, your child can learn how to get started with programming using the micro:bit. 

This course comes with a micro:bit and a couple of sensors, and it is the perfect way to get them interested in programming. 

Instead of learning programming through theory, your child will learn programming through doing. 

Date: 15 June 2019 (Saturday)
Time: 9am to 5pm
Lunch provided
Course Fee: S$395

Python Machine Learning - Wiley

What could be more exciting than receiving the advance copies of the book that you spent 6 months writing? #PythonMachineLearning

Dart Cheat Sheet

Learning a new framework is a daunting task. And it is totally nightmarish if a new language is used. Such is the case for learning Flutter, where the language used is Dart. To ease your Flutter learning curve, I have prepared the Dart Cheat Sheet so that you can focus on the Flutter framework, rather on the language syntax. 

Check it out here - http://bit.ly/2uCSLE3.

Kotlin Cheat Sheet

I have just updated the Kotlin Cheat Sheet. It is now 4 pages long! Includes the language basics as well as topics on OOP, Extension methods, Lambda functions and more.

Article - Implementing Push Notifications in Progressive Web Apps (PWAs) Using Firebase

Progressive Web Apps (PWAs) are Web applications that behave like native mobile applications. PWAs leverage Google technology to deliver an extremely engaging mobile experience. PWAs live within the Web browser and have the ability to work even if the device is offline. At the same time, PWAs exhibit the behavior that you’ve come to expect from native mobile apps: They support background content updating, push notifications, and more. More importantly, PWAs can be updated without needing to resubmit your applications to the app stores (both Apple and Google’s). 

In this article, I’ll discuss one of the most interesting and important features of PWA: Push Notifications. I’ll show you how to enable push notifications in your PWA application using Firebase Cloud Messaging (FCM). And, as a bonus, I’ll show you how to host your PWA on Firebase Hosting, as well as how to host your REST API as a serverless app through Firebase Functions. Keep your seat belt on, as this is going to be a very fun (and exciting) journey!
