Describe a situation where understanding the widget lifecycle is crucial for avoiding memory leaks in Flutter.
- Handling large lists without proper lifecycle management
- Handling stateful widgets with asynchronous operations
- Not managing subscriptions in initState()
- Using controllers or listeners with dispose()
Understanding the widget lifecycle is crucial for avoiding memory leaks, especially when using controllers or listeners. When these objects are used, it's essential to dispose of them properly to release resources and prevent memory leaks. This is typically done in the dispose() method, which is called when the widget is removed from the tree. Neglecting to dispose of controllers or listeners can lead to memory leaks, affecting the app's performance and stability over time.
