Asynchronous operations are a core part of any programming language and play a huge role in the development of modern mobile apps.

The Flutter team has put together a great mini-series on this topic. I highly recommend watching it.

What is the Future?

First of all, let’s understand what a Future is. From the docs:

A Future is used to represent a potential value, or error, that will be available at some time in the future.

In other words, a Future is an object that will at a certain point hold some value, but not currently. One example that you can think of it is like an oven that’s cooking something— an oven cooks something and eventually, you hear a “ding”. You look inside and what you wanted to cook is finally ready. The same thing goes for the Future — until you hear that “ding” your Future is in an uncompleted state. …

While working in the tech industry we’re constantly bombarded with information of various sorts. We always need to keep up with the new technologies, frameworks, new versions of the languages that we work with, etc.

Here are some tips that have worked for me and I hope they will be equally as valuable to you. Also, I highly recommend that you take this course to understand how we learn and how our brain functions. The points below are a mix of my personal experience and the useful tips I’ve amassed on this topic.

1. Pick what you really need to learn. I know that this sounds obvious but a lot of the time we get overwhelmed by the sheer amount of information we need to process. As programmers and perfectionists, we want to understand every bit of the topic that we need to get a grasp of. Very often this leads us going down a rabbit hole that effectively has no end. One topic transitions into another one and soon enough you find yourself learning stuff that you didn’t intend to. Don’t get me wrong — the more you know, the better, and I applaud people that are experts in a certain domain, but most of the time we need to just get a high-level understanding of something to do our job effectively. In terms of software engineering, my advice is to focus on learning the fundamentals of computer science instead of trying to learn every new framework that comes out. All of the latest frameworks are built on top of fundamentals. So get a good grasp on that and you will find it easier to get familiar with new stuff. …
