Building the Layout When building the layout, an important step is to know what they layout should look like first. You can sketch the layout on paper, or use a tool which helps build layouts. When looking at your sketch, you will want to identify all of the rows. There may be columns within the…
Today we’re going to work with some of the layout code to see how we can modify/create our own layouts. If you’ve not gone through Learning about Flutter Layouts, you may want to do that first. We’ll start by creating the basic application. We’ll then modify the title so we know what app we’re building….
Functions in Dart are very similar to function definitions in most C style languages. In addition to the main function, you can create your own function. To define a function, you will need to define a return type, a function name, and a parameter list. Now a function in Dart is a form of an…
Dart also allows you to store different types of collections of data. Just like primitive data types, you can either create your variables with implicit data types, or allow Dart to infer them. We’ll look at the three main types: Lists List are similar to arrays in Python, Java, C++, and C#. They are an…
Dart has some basic variables types that are available for you to use. Inferred Definitions Dart doesn’t require you to define the data type when you define a variable. You can use the var keyword and Dart will infer the data type based upon what it sees. Implicit Definitions Likewise, you can define the data…
Flutter is a framework built on top of the Dart programming language. If you’ve not heard of the Dart language, you are not alone. Dart is a newer language. It is an open source language, however it was initially developed by Google. It is designed to allow someone to write code for both native applications…
Once we’ve installed Flutter, and built the test app, we now want to look at what is in the source code, to get an idea of how we’re going to be building applications. For such a simple app, there is actually, quite a bit going on, but it’s simple enough to understand. Let’s look at…
Once you have installed Flutter, you will want to create a test application to verify. Sure, your probably ran Doctor, but an extra layer of testing won’t hurt. In VSC, on the PC press CTRL-SHIFT-P (On Mac CMD-SHIFT-P) to open the command. Start typing flutter, and click on Flutter: New Application Project. This will create…
