As you’ve seen in the UML class relationships, there is the ability to define a class, and a subclass. The subclass will get all of the properties and methods of the parent class, and can then add additional properties and methods that are not available in the parent. Consider two classes, a Shape2D and a…
There are a couple of new features we want to add to our Name Generator. These include saving our favorite names, changing the UI etc. Getting Ready to Display Favorites To save a favorite, we need to have a way to keep track of them. So in our state object, we’re going to add a…
In this example we’re going to look at loading external libraries, adding additional widgets and more, all to create a name generator. Our first step is to create a new Flutter App in VSC. We’ve done this before several times. This will setup all of the libraries and connections we need initially, however we do…
Building off of the concepts of animation within Flutter, now we want to look at how we’ll create animations within Flutter. Creating a New Basic App Let’s look at a simple example. To do so, we’re going to create a new Flutter app. Next, we are going to replace the code generated with the following…
In this section we’re going to look at how to perform some basic animations in Flutter to help enhance our UI (User Interface). The Flutter SDK provides you with some built-in animations which you can use to perform actions such as fading, sliding, and resizing. The animation system in Flutter is based on typed Animation objects. Widgets…
In this tutorial, we’ll be learning how to add interactivity to an object when I user clicks/taps on it. This is assuming you have completed the previous tutorial on Working with Layouts in Flutter. When we get done, we’ll have learned about responding to taps, creating a custom widget, and the differences between a stateful…
Loops in Dart a similar to loops in the C style languages. You have conditional loops (the while and do while) and counting loop (for). Additionally you have a for…in loop (like a for each). The For Loop This is identical to your for loop in C/C++/Java. This loop is good for going through a…
In addition to the standard conditional operators, Dart has a couple which, while standard are not used as often as used forms of conditions, such as the switch and the Ternary operator which we’ll see in a minute. The Switch The switch is a tool which when it can be applied allows for efficient checking of…
