Error handling
Understand how to handle errors in Dart using try, catch, and finally blocks to maintain app stability. Explore strategies for managing asynchronous failures in Flutter by safely catching exceptions during network calls to ensure responsive and reliable applications.
We'll cover the following...

When Dart encounters a severe problem that it does not know how to resolve, it throws an exception. If your code does not actively anticipate and "catch" this exception, the entire program will crash. To provide a good user experience, we must handle these errors gracefully so the application can recover or display a helpful message instead of freezing.
The try, catch, and finally blocks
We manage unpredictable code using a specific architectural structure consisting of up to three distinct ...
