Description

In this video tutorial, we build and talk about a Temperature Conversion application with Dart's Flutter Mobile Framework. We look at some of the widgets and features that we haven't talked about yet. This includes various input and feedback widgets such as the basic input box, the checkbox, the slider and the radio button. We look at how each of these widgets work in the context of our application and choose one that works the best for this application.

We also look at a different way to refactor flutter widget trees. This method was highlighted specifically because some people have mentioned that they believe flutter to be too verbose and confusing. By refactoring the widgets into smaller components and variables, we are able to isolate the behavior into chunks. This method also gives us an easier to reason about the spacial layout of the widgets in a flutter user interface. We take a quick look at the Visual Studio Code Flutter paint debug mode which lets us look at our applications and see how the flutter framework is rendering and painting each of our widgets.
