In Blazor, components go through a lifecycle that includes various stages from initialization to disposal. The key methods that define this lifecycle are:

  1. OnInitialized: This method is called when a component is initialized, allowing you to perform initialization logic.

  2. OnParametersSet: Invoked when parameters are set for the component, enabling you to react to parameter changes.

  3. OnAfterRender: Executes after the component has been rendered, useful for interacting with the DOM or JavaScript.

  4. OnDispose: Called when a component is about to be removed, giving you a chance to clean up resources.

Understanding these methods and their respective stages in the component lifecycle is crucial for managing state, handling updates, and optimizing performance in Blazor applications.
