State Management Development Tutorials, Guides & Insights

Closures are essential because they enable powerful and flexible programming techniques. They allow you to:

• Encapsulate private data: Closures can help you create data that cannot be accessed directly from outside the function.
• Create factory functions: Closures can generate functions with specific behaviors or data preloaded.
• Maintain state across function calls: Closures allow you to maintain and manipulate the state of variables across multiple function calls.

Test the app by entering different city names and observing the weather data displayed.

In this tutorial, we built a more advanced Flutter app that fetches real-time weather data using an API and displays it with a user-friendly interface. We covered:

• lib/main.dart: The main entry point for your Flutter application.
• pubspec.yaml: The configuration file where you specify dependencies.
• android/ and ios/: Platform-specific code.

Let’s create a simple counter app to understand Flutter’s basic concepts.

   npx create-react-app my-react-app

This command will create a new directory called my-react-app with all the necessary files and dependencies.
