Description
In the Flutter Provider Essential course, you can learn in depth about Provider, the most basic and widely used among Flutter state management solutions.
If you want to deepen your understanding of the Flutter Provider and put all the concepts into practice, then this course is for you.
The lecture was carefully composed to ensure a balance between theory and practice.
And under the belief that repetition is the most important learning method, whenever there is a new concept, we will test the concept by making a small app, and through real-world apps such as TODO, Weather, and Firebase Authentication app, the concepts will come together comprehensively.
In particular, we will repeatedly practice combinations of different Providers when creating TODO, Weather, and Firebase Authentication apps.
- TODO App (3 Implementations): 1. Combination of ChangeNotifierProvider, ChangeNotifierProxyProvider, 2. Combination of ChangeNotifierProvider and ProxyProvider, 3. StateNotifierProvider
- Weather App (3 Implementations): 1. Combination of ChangeNotifierProvider, ChangeNotifierProxyProvider, 2. Combination of ChangeNotifierProvider and ProxyProvider, 3. StateNotifierProvider
- Firebase Authentication App (2 Implementations): 1. Combination of StreamProvider , ChangeNotifierProvider, and ChangeNotifierProxyProvider, 2. Combination of StreamProvider and StateNotifierProvider
In addition, I will talk about StateNotifier and StateNotifierProvider, which allow you to use the Provider as a more advanced State Management Solution, and there will be opportunities to practice through apps, so you will have even more options.
I can proudly say that this course is the most in-depth course on Flutter Provider.
This is a quick look at everything covered in the course.
