  7 Years of Software Engineering Advice in 18 Minutes  The Essence of Software Engineering The core of software engineering can be broken down into three principles: Create Solution To a Problem The problem you’re solving doesn’t always have to be technical; it could be any kind of issue. Software engineering is simply about applying technical skills to solve real-world problems. 1. What Makes a Good Software Engineer? – Communication Skills Surprisingly, programming isn’t the most important skill for a software engineer. Here’s why: Most software engineers can solve a problem when given the right directions. They’ve already proven their technical abilities by passing interviews.

 Yes, understanding lists is very important when working with Dart, especially in Flutter. Let me guide you through the core concepts of lists in Dart. What is a List in Dart? In Dart, a list is an ordered collection of elements. Lists are very similar to arrays in other programming languages. They allow you to store multiple values in a single variable, and the values are indexed, starting from zero. Types of Lists in Dart Fixed-Length List : The length of the list is defined when the list is created and cannot change later. Growable List : The length of the list is not fixed and can change dynamically as you add or remove elements. By default, Dart lists are growable, but you can also create fixed-length lists if needed. Core Concepts of Lists Declaring and Initializing a List : You can create a list using either literals or constructors. dart // Using list literals List<int> numbers = [1, 2, 3, 4, 5]; // Using the List constructor (growable) List<String> fruits = L...
