Can you explain what is meant by configuration in the context of software systems?

Configuration in software systems is a set of parameters and settings that determine the application's behavior without changing the source code. This can include:

• Configuration files (e.g., JSON, YAML, XML).
• Environment variables.
• Command-line parameters.

In Flutter, configuration may include API keys, server addresses, theme settings, and other values that the application reads at startup. This allows for flexible changes to the application's behavior across different environments (development, testing, production) without recompilation.
