Provider - Flutter Advanced State Management

What is Flutter Provider ?

• In Flutter State Management of variables is difficult, so people started using BLoC .

But BLoC is not easy to understand and there is a lot of Boilerplate code.

So Flutter introduces a new way to Manage State using Providers.

How Provider Works?

• So there are basically three things:

1. ChangeNotifierProvider Widget

2. Model Class with ChangeNotifier

3. The Wigdets(in seperate class) for which the state to be managed

• So the widgets for which the state to be managed are wrapped inside the ChangeNotifierProvider Widget

• then the Model class is provided for the ChangeNotifierProvider

• So whenever there is a state change in model class, it will send notification to each widget(only changed ones)

• And the widgets then rebuild their ui

What's this Provider Demo App do?

• So it is implementation of flutter Providers State Management Concept.

• The App on Start fetches data from a api

And shows image and title from that data.

• By clicking that fab(refresh) button it fetches new data from the same api with a random generated id...
