This course is designed to guide you through the process of building your first app using Flutter, a popular cross-platform framework for mobile application development. The course assumes that you are familiar with the object-oriented programming paradigm, which is a fundamental programming approach used in many modern programming languages, including Dart (the language used in Flutter).

In this course, you will learn how to build a Todo app, which will have CRUD functionality. You will also learn how to design the user interface of the app using Flutter widgets and handle user input and data storage using Firebase, a popular backend-as-a-service platform. Moreover, you understand how to monetize your app by integrating AdMob and InAppPurchases. 

By the end of the course, you will have a working Todo app that you can publish on the Google Play Store. You will also have a solid foundation in using Flutter, Firebase, AdMob, and InAppPurchases to build and monetize your mobile applications.

Build and Publish Your First Mobile App Using Flutter

# State management

All modern app developments require some kind of state management. The bigger the app is, the more sophisticated a state management solution is required to be. Previously, we discussed [how stateful and stateless widgets function](https://www.educative.io/courses/build-and-publish-your-first-mobile-app-using-flutter/stateful-and-stateless-widget) in Flutter. The most common way to update a state is to use stateful widgets and the `setState` function.

# Usecase
When we build apps on the frontend, there are various states that keep changing because of user interactions. Some of them reside on a single page, like a radio button switch that is set to an on or off state. Some of these reside globally, like how the theme of the app can be switched from a light theme to a dark theme.

Flutter is a declarative language. Flutter's user interface is designed to represent the current status of our program. When the state of our app changes, we modify the state, which causes the user interface to redraw.

There are various third-party packages out there that tackle this problem, each with a unique approach. We can find a [list of third-party packages](https://docs.flutter.dev/development/data-and-backend/state-mgmt/options) in Flutter's documentation.

In our course, we'll use the provider package to manage our app's state.
