+title: MobX versus Inherited Model
+---
+
+`MobX` and [`InheritedModel`](https://api.flutter.dev/flutter/widgets/InheritedModel-class.html) are both state management solutions for Flutter apps, but they have different strengths and weaknesses.
+
+**`MobX` is a more complex library, but it offers a number of advantages over InheritedModel, including:**
+
+- Reactivity: MobX uses a reactive programming model, which means that changes to state are automatically reflected in the UI. This can simplify your code and make it easier to maintain.
+- Centralized state management: MobX allows you to manage all of your app's state in one place, which can make it easier to debug and reason about your code.
+- Performance: MobX is highly optimized and can provide significant performance benefits for complex apps.
+
+**`InheritedModel` is a simpler library, but it also has some limitations:**
+
+- Manual updates: InheritedModel does not automatically update the UI when state changes. You must manually call the notifyListeners() method to notify the UI of changes.
+- Decentralized state management: InheritedModel is a decentralized state management solution. This means that state can be scattered throughout your app, which can make it difficult to debug and reason about.
+- Performance: InheritedModel can be less performant than MobX for complex apps.
+
+### When to use MobX:
+
+- You are building a complex app with a lot of state.
+- You want to use a reactive programming model.
+- You want to centralize state management.
+- You need high performance.
+
+
+### When to use InheritedModel:
+
+- You are building a simple app with a little bit of state.
+- You want to use a decentralized state management solution.
+- You need a simple solution that is easy to learn and use.
+- You are not concerned about performance.
+
+
+### Which one should you use?
+
+It depends on your specific needs. If you are building a complex app with a lot of state, you should use MobX. If you are building a simple app with a little bit of state, you can use InheritedModel.
+
+### Can the Inherited Model completely replace MobX?
+
+Yes, the Inherited Model can completely replace MobX. However, it is important to note that the Inherited Model is a more manual solution. You will need to manually update the UI when state changes, and you will need to manage state yourself.
+
+If you are looking for a more powerful and automated state management solution, then MobX is a better choice. However, if you need a simple solution that is easy to learn and use, then the Inherited Model is a good option.
