Description
During this course, you can learn more about Provider, which is the most common and basic Flutter state management tool.
If you want to learn more about the Flutter Provider and put what you learn into practice, this course is for you.
The lecture was carefully planned to make sure there was a good mix of theory and practice.
And because we believe that repetition is the best way to learn, whenever we learn a new thing, we’ll make a small app to test it out. Then, through apps like TODO, Weather, and the Firebase Authentication app, the concepts will come together completely.
When we make apps like TODO, Weather, and Firebase Authentication, we’ll practice combining different providers over and over again.
TODO App has 3 implementations: 1. ChangeNotifierProviderProxyProvider 2. ChangeNotifierProxyProvider 3. In this case, the ChangeNotifierProvider and ProxyProvider are combined. This is the third service that notifies you when your state changes.
Weather App: 3 implementations: 1. ChangeNotifierProviderProxyProvider 2. ChangeNotifierProxyProvider 3. ChangeNotifierProxyProvider In this case, the ChangeNotifierProvider and ProxyProvider are combined. This is the third service that notifies you when your state changes.
– Firebase Authentication App: There are 2 ways to use this app. 1. A StreamProvider, a ChangeNotifierProvider, and a ChangeNotifierProxyProvider. 2. A StreamProvider and a StateNotifierProvider together.
StateNotifier and StateNotifierProvider will also be talked about. These are two tools that let you use the Provider to manage your state in a more advanced way, and there will be opportunities to practice with applications so you have even more ways to do this.
