What is Provider in FlutterĪs the name suggests, Provider is a Flutter architecture that provides the current data model to the place where we currently need it. We do not have direct references to other views in the tree, from which we could gain their current state. Data available in one place in the application are not so easy to obtain in another. This completely changes the approach to managing the sate that native Android or iOS developers were familiar with, writing the code imperatively. Brief introduction to Flutter architectureĬhoosing the architecture for a Flutter project is of great importance, primarily due to the fact that we are dealing with a less commonly used, declarative programming paradigm. As a result, we will learn the pros and cons of each solution, which will help us choose the right Flutter architecture for our next module or application. In this article, we will go through the most popular screens in mobile applications and implement them in the two most popular Flutter architectures: Provider and BLoC. When you get that answer, you can be sure you found an expert in programming. As is often the case, the best answer to the question “Which one should I choose?” is “It depends”. Writing apps with Flutter creates great opportunities for choosing architecture.
