Flutter SDK is an excellent tool for developing cross-platform applications from a single codebase. So, it's no surprise that many professionals and learners have decided to gain mastery over Flutter concepts.

One such concept is state management, and many, despite having intermediate-to-advanced proficiency in Flutter, still struggle with this concept. This course will help you learn and master the best practices for state management in Flutter.

You will learn to use the two best Flutter libraries, Riverpod and Provider, for state management. You will even learn about reducing widget rebuilds by managing their state.

What is a map in Flutter? How do you map a list in Flutter?

Before exploring these questions, we should know how to use lists in Flutter. Moreover, we must understand the primary concepts of data structure in the Dart programming language. The same applies to the map.

Once we understand how to use a list in Dart, it becomes easier to understand maps.





# A state management concept

**We cannot change the state of a stateless widget through its property, but we can change the condition externally.** Especially when we pass the external data through its constructor.

We have created two custom widgets, `Answers` and `Questions` based on that assumption. We pass two parameters through the `Answers` constructor: a function and a string data type.

At the same time, we have also created another custom widget, `Questions`, with only one piece of external data to be passed, which is a string.

# Introduction to a map in Flutter

A map is a list of elements where we arrange the elements in a key-value pair. In a list, there is always an index that starts from 0, and that index allows us to get the value. In a map, the key allows us to get the value. As a result, we use different types of methods in maps. Moreover, we can also include a map in our list and vice versa.
We do exactly that here.

Let us see two custom widgets first.
